Comparison of Postoperative Seizures Between Burr-Hole Evacuation and Craniotomy in Patients With Nonacute Subdural Hematomas: A Bi-Institutional Propensity Score-Matched Analysis.

Postoperative seizures are a common complication after surgical drainage of nonacute chronic subdural hematomas (SDHs). The literature increasingly supports the use of prophylactic antiepileptic drugs for craniotomy, a procedure that is often associated with larger collections and worse clinical status at admission. This study aimed to compare the incidence of postoperative seizures in patients treated with burr-hole drainage and those treated with craniotomy through propensity score matching (PSM). A retrospective cohort analysis was conducted on patients with surgical drainage of nonacute SDHs (burr-holes and craniotomies) between January 2017 to December 2021 at 2 academic institutions in the United States. PSM was performed by controlling for age, subdural thickness, subacute component, and preoperative Glasgow Coma Scale. Seizure rates and accompanying abnormalities on electroencephalographic tracing were evaluated postmatching. A total of 467 patients with 510 nonacute SDHs underwent 474 procedures, with 242 burr-hole evacuations (51.0%) and 232 craniotomies (49.0%). PSM resulted in 62 matched pairs. After matching, univariate analysis revealed that burr-hole evacuations exhibited lower rates of seizures (1.6% vs 11.3%; P = .03) and abnormal electroencephalographic findings (0.0% vs 4.8%; P = .03) compared with craniotomies. No significant differences were observed in postoperative Glasgow Coma Scale (P = .77) and length of hospital stay (P = .61). Burr-hole evacuation demonstrated significantly lower seizure rates than craniotomy using a propensity score-matched analysis controlling for significant variables.

Microsurgical treatment of ophthalmic artery aneurysm, a case series of 55 patients with long-term follow-up

BackgroundOphthalmic artery aneurysm (OAA) can be secured in endovascular or microsurgical approaches. Still there are controversies in technique selection and their long term outcomes.MethodsAll the patients with OAA were treated microsurgically and followed. Demographic data, neurological status, physical examination findings, angiographic data, operation details, and intraoperative and postoperative events were recorded and analyzed. P < 0.05 was considered significant.ResultsAmong 55 patients, 38 were females (69.1%). Median preoperative glasgow coma scale (GCS), Fisher Grade, and Hunt and Hess(HH) scores were 15, 1 and 1, respectively. The most common neurologic manifestation was visual problems (n = 15). The most common anatomical projection was medial (43.6%) oriented lesions. 85.5% of them only had 1 ophthalmic aneurysm while multiple aneurysms were reported in 14.6%. In 52 patients temporary clip was used. in 21 patients (38.2%) intraoperative aneurysm rupture occurred. Larger aneurysm size and preoperative hydrocephalus were associated with higher rates of aneurysm rupture (P = 0.003 and 0.031). 28.5% of the patients with visual problems had clinical improvement in the postoperative period. The mean follow-up period was 5 years. Follow-up angiography showed a 100% obliteration rate with a 0.0% recurrence rate. Median values for follow-up glasgow outcome scale and modified Rankin scale were 5 and 0, respectively. favorable neurological outcomes were associated with better primary GCS and HH scores.ConclusionOAA microsurgery is an effective and safe procedure with significant improvement in both visual and neurological status. Low recurrence rate and excellent clinical recovery are the most important advantages of microsurgery in OAA treatment.

Endoscopic Management of Chronic Subdural Hematoma Using a Novel Brain Retractor

Endoscopic procedures are useful in chronic subdural hematoma especially when there are septations, solid/organized hematoma, and the presence of bridging or neovessels in the cavity. Visualizing the distal hematoma cavity by a rigid scope is challenging in large and curved ones due to the hindrance by the brain surface. Combining rigid endoscopy and brain retractor can overcome this limitation. A retrospective study of 248 patients managed by endoscopic technique was performed and the relevant literature was reviewed. The brain retractor was used in all patients. Average operative time, subgaleal drainage duration, and hospital stay were 56minutes, 3.1days, and 4.6days, respectively. The average preoperative Glasgow coma scale (GCS) score was 12, which improved to 14 and 15 in 223 and 23 patients, respectively at discharge. There were solid clots, septations, bridging vessels, curved hematoma cavities, rapid expansion of the brain after partial hematoma removal, and recurrences in 59, 52, 15, 49, 19, and 2 patients, respectively. There were 2 deaths, without any procedure-related mortality. Endoscope was very effective and safe in the management of chronic subdural hematoma, especially in about 51% patients with solid clots, septations, and bridging vessels which could have been difficult to treat by conventional burr hole. It can avoid craniotomy in such patients. Good visualization and complete hematoma removal were possible with the help of an endoscope and brain retractor in about 27% of patients which could have been difficult with a rigid endoscope alone.

Cisternostomy is not beneficial to reduce the occurrence of post-traumatic hydrocephalus in Traumatic Brain Injury.

The Cisternostomy is a novel surgical concept in the treatment of Traumatic Brain Injury (TBI), which can effectively drain the bloody cerebrospinal fluid from the skull base cistern, reduce the intracranial pressure, and improve the return of bone flap, but its preventive role in post-traumatic hydrocephalus (PTH) is unknow. The purpose of this paper is to investigate whether Cisternostomy prevents the occurrence of PTH in patients with moderate and severe TBI. A retrospective analysis of clinical data of 86 patients with moderate and severe TBI from May 2019 to October 2021 was carried out in the Brain Trauma Center of Tianjin Huanhu Hospital. Univariate analysis was performed to examine the gender, age, preoperative Glasgow Coma Scale (GCS) score, preoperative Rotterdam CT score, decompressive craniectomy rate, intracranial infection rate, the incidence of subdural fluid, and incidence of hydrocephalus in patients between the Cisternostomy group and the non-Cisternostomy surgery group. we also analyzed the clinical outcome indicators like GCS at discharge,6month GOS-E and GOS-E ≥ 5 in two groups.Additionaly, the preoperative GCS score, decompressive craniectomy rate, age, and gender of patients with PTH and non hydrocephalus were compared. Further multifactorial logistic binary regression was performed to explore the risk factors for PTH. Finally, we conducted ROC curve analysis on the statistically significant results from the univariate regression analysis to predict the ability of each risk factor to cause PTH. The Cisternostomy group had a lower bone flap removal rate(48.39% and 72.73%, p = 0.024)., higer GCS at discharge(11.13 ± 2.42 and 8.93 ± 3.31,p = 0.000) and better 6month GOS-E(4.55 ± 1.26 and 3.95 ± 1.18, p = 0.029)than the non-Cisternostomy group However, there was no statistical difference in the incidence of hydrocephalus between the two groups (25.81% and 30.91%, p = 0.617). Moreover, between the hydrocephalus group and no hydrocephalus group,there were no significant differences in the incidence of gender, age, intracranial infection, and subdural fluid. While there were statistical differences in peroperative GCS score, Rotterdam CT score, decompressive craniectomy rate, intracranial infection rate, and the incidence of subdural fluid in the two groups, there was no statistical difference in the percentage of cerebral cisterns open drainage between the hydrocephalus group and no hydrocephalus group (32.00% and 37.70%, p = 0.617). Multifactorial logistic binary regression analysis results revealed that the independent risk factors for PTH were intracranial infection (OR = 18.460, 95% CI: 1.864-182.847 p = 0.013) and subdural effusion (OR = 10.557, 95% CI: 2.425-35.275 p = 0.001). Further, The ROC curve analysis showed that peroperative GCS score, Rotterdam CT score and subdural effusion had good ACU(0.785,0.730,and 0.749), with high sensitivity and specificity to predict the occurrence of PTH. Cisternostomy may decrease morbidities associated with removal of the bone flap and improve the clinical outcome, despite it cannot reduce the disability rate in TBI patients.Intracranial infection and subdural fluid were found to be the independent risk factors for PTH in patients with TBI,and the peroperative GCS score, Rotterdam CT score and subdural effusion had higher sensitivity and specificity to predict the occurrence of PTH. And more importantly, no correlation was observed between open drainage of the cerebral cisterns and the occurrence of PTH, indicating that Cisternostomy may not be beneficial in preventing the occurrence of PTH in patients with moderate and severe TBI.

Clot removAl with or without decompRessive craniectomy under ICP monitoring for supratentorial IntraCerebral Hemorrhage (CARICH): a randomized controlled trial.

Decompressive craniectomy, a surgery to remove part of the skull and open the dura mater, maybe an effective treatment for controlling intracranial hypertension. It remains great interest to elucidate whether decompressive craniectomy is beneficial to intracerebral hemorrhage patients who warrant clot removal to prevent intracranial hypertension. The trial was a prospective, pragmatic, controlled trial involving adult patients with intracerebral hemorrhage who were undergoing removal of hematoma. Intracerebral hemorrhage patients were randomly assigned at a 1:1 ratioto undergo clot removal with or without decompressive craniectomy under the monitoring of intracranial pressure. The primary outcome was the proportion of unfavorable functional outcome (modified Rankin Scale 3-6) at 3 months. Secondary outcomes included the mortality at 3 months and the occurrence of re-operation. A total of 102 patients were assigned to the clot removal with decompressive craniectomy group and 102 to the clot removal group. Median hematoma volume was 54.0 mL (range 30-80mL) and median preoperative Glasgow Coma Scale was 10 (range 5-15). At 3 months, 94 patients (92.2%) in clot removal with decompressive craniectomy group and 83 patients (81.4%) in the clot removal group had unfavorable functional outcome (P=0.023). Fourteen patients (13.7%) in the clot removal with decompressive craniectomy group died versus five patients (4.9%) in the clot removal group (P=0.030). The number of patients with re-operation was similar between the clot removal with decompressive craniectomy group and clot removal group (5.9% vs. 3.9%; P=0.517). Postoperative intracranial pressure values were not significantly different between two groups and the mean values were less than 20mmHg. Clot removal without decompressive craniectomy decreased the rate of modified Rankin Scale score of 3-6 and mortality in patients with intracerebral hemorrhage, compared with clot removal with decompressive craniectomy.

Prediction of functional outcome in supratentorial intracerebral hemorrhage patients treated with stereotactic computed tomographic-guided aspiration and recombinant tissue plasminogen activator (rt-PA)

Background and purposeMinimally invasive surgery for ICH has shown a significantly improved functional outcome for selected ICH patients. This study aimed to evaluate the factors influencing the outcome of supratentorial ICH patients treated with stereotactic computed tomographic (CT) guided recombinant tissue plasminogen activator (rt-PA). MethodsWe retrospectively evaluated data from 80 consecutive supratentorial ICH patients between December 2017 and July 2020, analyzing their 180-day outcomes, and identifying clinical, radiological factors for good prognosis within 180 days. ResultsThe mean age was 55.6 years (SD 11.4). The median preoperative Glasgow Coma Scale (GCS) score was 9 (interquartile range - IQR 6–12). The mean final ICH volume was 26.5 ml (SD 27.5), with ICH volume reduction by an average of 66.7 %. Six months after the procedure, 40 patients (50 %) had favorable outcomes (modified Rankin Scale [mRS]) score 0–3). In multivariate analysis, age (odds ratio [OR] = 0.939, 95 % confidence interval (CI) = 0.894 – 0.986; p = 0.012), the GCS score before operation (OR = 1.525, 95 % CI = 1.008 – 2.309; p = 0.046), the initial midline shift (OR = 0.808, 95 % CI = 0.661 – 0.988; p = 0.038), and the residual volume hematoma (OR = 0.949, 95 % CI = 0.908 – 0.992, p = 0.020) were the significant predictors of a favorable 180-day outcome. Receiver operating characteristic curve analysis confirmed that the best cut-off point for predicting the good functional 180-day outcome was a GCS score of 9 before the procedure [area under the curve: 0.721, 95 % CI = 0.608 – 0.833, p = 0.001]. ConclusionCT-guided thrombolysis and aspiration can be safe and effective in reducing ICH volume. A preoperation GCS score above or equal to 9 and younger age were associated with improved long-term outcomes in patients with supratentorial ICH.

Emergency decompressive surgery in patients with transtentorial brain herniation and pupillary abnormalities: the importance of improved pupillary response after osmotherapy and surgery.

The predictors of survival and functional recovery following emergency decompressive surgery in patients with transtentorial brain herniation, particularly those with pupillary abnormalities, have not been established. In this study, the authors aimed to assess the outcome of patients with intracranial mass lesions, transtentorial brain herniation, and nonreactive mydriasis, following emergency surgical decompression. A retrospective chart review was performed of all patients with transtentorial herniation and pupillary abnormalities who underwent craniotomy or craniectomy at two trauma and stroke centers between 2016 and 2022. The functional outcome was determined using the modified Rankin Scale (mRS). Forty-three patients, 34 men and 9 women with a mean age of 47 years (range 16-92 years), were included. The underlying etiology was traumatic brain injury in 33 patients, hemorrhagic stroke in 8 patients, and tumor in 2 patients. The median preoperative Glasgow Coma Scale score was 3 (range 3-8), and the median midline shift was 9 mm (range 1-29 mm). Thirty-two patients (74.4%) had bilaterally fixed and dilated pupils. The median time to surgery (from pupillary changes) was 133 minutes (mean 169 minutes, range 30-900 minutes). Eighteen patients (41.9%) died postoperatively. After a median follow-up of 12 months (range 3-12 months), 11 patients (26.8%) had a favorable functional outcome, while 10 remained severely disabled (mRS score 5). On univariate analysis, younger age (p < 0.001), less midline shift (p = 0.049), and improved pupillary response after osmotic therapy (p < 0.01) or decompressive surgery (p < 0.001) were associated with favorable outcomes at 3 months. With aggressive medical and surgical management, patients with transtentorial brain herniation, including those with bilaterally fixed and dilated pupils, may have considerable rates of survival and functional recovery. Young age, less midline shift, and improved pupillary response following osmotic therapy or decompressive surgery are favorable prognosticators.

Comparison of the decompressive craniectomy results in patients with ischemic stroke and acute subdural hematoma and determination of prognostic markers

Aims: This study aimed to investigate the therapeutic effectiveness of decompressive craniectomy in patients with traumatic acute subdural hematoma and stroke patients and to determine the parameters that could predict the risk of mortality in these patients. Methods: Patients diagnosed and operated on with acute subdural hematoma (ASH) or stroke between January 2022 and September 2023 were grouped into the ASH group and the CVO group. The patients were also divided into DEAD and SURVIVED groups according to mortality. Age, gender, anisocoria, the area of the craniectomy field, length of stay in the intensive care unit (ICU), length of stay in the hospital, and Glasgow Outcome Scale scores were recorded. In addition, Glasgow Coma Scale (GCS) scores, the amount of midline shift, and the blood biochemistry results were recorded pre-and postoperatively. Results: This study consisted of 11 (5 male and 6 female) patients. Sex, preoperative GCS score, anisocoria, postoperative sedation anesthesia time, postoperative GCS score, duration of stay in the ICU, preoperative serum blood urine nitrogen, preoperative serum C-reactive protein (CRP), postoperative neutrophil-to-lymphocyte ratio, and postoperative CRP values were different between the ASH and CVO groups (p&lt;0.05). Furthermore, the preoperative GCS score, postoperative GCS score, postoperative sedation anesthesia duration, postoperative serum aspartate aminotransferase (AST), and postoperative serum CRP level values were different between the DEAD and SURVIVED groups (p&lt;0.05). The correlation analysis results revealed a positive correlation between mortality and preoperative GCS score and a negative correlation between mortality and anisocoria (p&lt;0.05). The ROC-curve analysis revealed that preoperative GCS and postoperative GCS score, postoperative midline shift, postoperative serum AST level value, and postoperative serum CRP level value could predict mortality risk (p&lt;0.05). However, Logistic Regression analysis showed that any study parameter could be used as the best marker for prediction of the postoperative mortality risk (p&gt;0.05). Conclusion: This study showed that decompressive craniectomy may offer more satisfactory results in severe head trauma patients. It was also argued that preoperative and postoperative GCS scores, postoperative midline shift values, and postoperative serum AST and CRP level values could be used to predict mortality risk.

Prevalence of Low Back Pain and Its Related Risk Factors and Disability Following Lumbar Discectomy: A Single-Center Study.

Background Lumbar disc herniation is considered the most common cause of sciatica, which is a contributing factor to disability. Surgical management of lumbar disc herniation in the form of discectomy is superior to conservative management in terms of better recovery and pain relief. However, recurrence, residual back pain, and disability are common expected complications following surgery. Therefore, this study aims to determine the prevalence of low back pain and its related risk factors and disability following discectomy at King Fahad Hospital in the Al-Ahsa region. Methodology A cross-sectional study was conducted at King Fahad Hofuf Hospital in the Al-Ahsa region among patients who were admitted and underwent lumbar spine discectomy in the last six years either due to traumatic or degenerative causes. The study used an anonymous questionnaire consisting of the patient's sociodemographic data, medical and surgical history, spine disease history, and surgical history. The preoperative Glasgow Coma Scale score, neurological status, and American Spinal Cord Impairment Scale score were noted. In addition, immediate postoperative neurological status and minor complications were recorded. Moreover, more than six months postoperatively, the Numeric Analogue Scale and the Oswestry low back pain disability index questionnaire were administered. Results A total of 201 patients were included in the study. The majority of the patients were male (59.7%), with ages ranging from 41 to 60 years (51.7). Most patients underwent one surgery (83.6%) in the form of discectomy alone (90.5%) at L3-L4 (58.7%), for which the intervertebral disc was the most common degenerative indication for surgery. All patients (100%) had low back pain preoperatively, and most patients (50.7%) had no back pain six months postoperatively. Preoperatively, 58.2% had diminished neurological status, while only 29.9% showed a deficit postoperatively. Postoperative low back pain was significantly associated with office-based jobs (p = 0.021, 60.5%) and a high number of surgeries (p = 0.004, 74.1%). The following factors were observed to be risk factors for having lower back pain: six months postoperatively, being unemployed (p = 0.024, odds ratio = 4.38, 338% increased risk), having an office-based job (p = 0.012, odds ratio = 3.98, 298% increased risk), and the underlying cause of the problem being degenerative (p = 0.003, odds ratio = 3.34, 234% increased risk). Low back pain-related severe disability postoperatively was significantly associated with increased age >40 (28-50%; p = 0.045), female gender (p = 0.012, 44.4%), and being unemployed (p = 0.002, 51.4%). The level of disability six months postoperatively was moderate in 40.4% of the patients. Conclusions Lumbar discectomy is a successful procedure for relieving low back pain among patients with degenerative spine disease, with an improvement that involves neurological status. However, residual back pain may still occur in less than half of the patients despite appropriate management, such as being unemployed or office-based employees and having multiple spine surgeries. However, low back pain-related disability is often moderate, with increasing severity seen with increased age, being female, and being unemployed.

Intraoperative ultrasonographic-guided surgery of intracerebral hemorrhage

Abstract Background The location of the cortical incision and maximum evacuations of parenchymal intracerebral hematoma are crucial points. Intraoperative ultrasonography is a real-time tool with great benefit at these points Methods A retrospective study of patients with parenchymal intracerebral hemorrhage that underwent evacuation using intraoperative ultrasound guidance was included. Preoperative clinical and radiological assessments were studied. The postoperative imaging and clinical outcome were assessed. A late follow-up after 6 months was done. Results The age of study patients ranged from 9 to 73 (mean 45.3 ± 20.4 years). There were 14 males (58.3%). The mean preoperative Glasgow Coma Scale (GCS) was 9.8 ± 2.9. The preoperative hematoma volume ranged from 32 to 135 cm3 with a mean of 68.5 ± 30.5 cm3. The rate of evacuation ranged from 90 to 100%. The mean postoperative GCS was 11.7 ± 2.5. None of the patients had a recurrent hemorrhage. There was a significant rate of evacuation of the hematomas (P value &lt; 0.001*). Also, there was a marked improvement in postoperative GCS and the late modified Rankin Scale (P value &lt; 0.001*). Conclusion Ultrasonography is a useful, efficient, real-time tool for the localization and evacuation of parenchymal intracerebral hemorrhage. It maximizes evacuation and decreases parenchymal insult. It is an important aid to the neurosurgeon.

Perioperative Outcomes following Surgery of Brain Tumors: Assessment and Analysis of Risk Factors

Introduction: Cranial neurosurgery carries significant morbidity and mortality. Hence it is imperative to combine the latest available technological equipment with surgeon’s experience to prevent or reduce perioperative complications. It is also equally important to have a preoperative general assessment of the patient with functional status in particular to predict postoperative outcomes. Methods: This is a prospective study consisting of 122 patients selected over a period of 5 years (March 2017-March 2022). The patient database was retrieved from the medical record department, Nobel Institute of Neurosciences, Nobel Medical College Teaching Hospital, Biratnagar, Nepal and the approval of Institutional review committee was obtained. Age, gender, tumor related factors (site, extent and size), preoperative Glasgow Coma Scale (GCS) score, Karnofsky Performance Status (KPS) score and Modified Rankin scale (mRS) grade and their correlation with patient’s perioperative outcome were assessed. Results: Significant correlation was found between preoperative KPS score, mRS grade and patient’s perioperative outcome (low KPS score &lt;70 and high mRS grade was associated with adverse outcomes). There was no positive correlation between age, gender and tumor related factors with outcomes. Conclusion: Low KPS score &lt;70 and a high Modified Rankin scale score were associated with adverse perioperative outcomes in patient’s undergoing elective craniotomy for brain tumor surgery.

Early Clinical Outcome of Mini-Craniotomy in Mixed Density Subdural Hematoma

Objective: To determine the efficacy of mini-craniotomy for evacuation of mix-density subdural hematoma in terms of early clinical outcome.&#x0D; Study Design: Quasi-experimental study.&#x0D; Place and Duration of Study: Neurosurgery Department, Combined Military Hospital, Rawalpindi Pakistan, from Jan to Dec 2020.&#x0D; Methodology: Eighty patients with mixed-density subdural hematoma were included in the study. All were subjected to minicraniotomy under general anaesthesia. Post-operative Glasgow Coma Scale (GCS) was monitored and compared with the preoperative Glasgow Coma Scale (GCS) to see the early clinical outcome of the patients.&#x0D; Results: Out of 80 patients with mixed-density subdural, 38(47.5%) were females, whereas 42(52.5%) were males. The mean age of the patients was 70.9±6.98 years. Improvement in Glasgow Coma Scale (GCS) after 24hrs showed that 68(85%) patients had a favourable outcome, while 12(15%) had the same condition post-operatively.&#x0D; Conclusion: Mini-craniotomy is a suitable surgical procedure for the treatment of mixed-density subdural hematoma.

Traumatic Cranial Dural Venous Sinus Injury

Purpose: The study's objective is to elucidate and discuss the causes of traumatic dural venous sinus injury and make comparisons between these causes. The aim is also to assess the susceptibility of dural sinuses to injury in descending orders. Additionally, the research examines the relationship between types of fracture and the challenges in controlling bleeding in patients with traumatic dural venous sinus injury. Furthermore, the study analyzes the factors that influence the morbidity and mortality rate among patients with traumatic dural venous sinus injury. Methodology: Between January 2021 and October 2022, a prospective study was carried out, involving 22 patients diagnosed with dural venous sinus injury. The study encompassed both surgically and conservatively treated patients. For each participant, demographic information, such as age, sex, causative trauma, preoperative GCS, preoperative deficit, image findings, name, and part of the injured sinus, as well as the presence and absence of a fracture and its relation to the sinus were recorded. The intraoperative method employed to control bleeding and the amount of blood transfusion were also documented, along with postoperative GCS and postoperative complications. The Glasgow Coma Scale (GCS) score was utilized to assess the neurological outcome. Findings: The most frequently injured dural venous sinus was the superior sagittal sinus, accounting for 77.3% of cases (8).Among patients with a linear skull fracture crossing the venous sinus, 83.3% had bleeding that could be easily controlled by placing Gelfoam over the injured sinus . However, in patients with a skull fracture parallel to the sinus over the venous sinus and those with depressed fractures (with/without penetration), we encountered greater difficulty in controlling bleeding (14). Only 16.7% and 10% of these cases, respectively, were easily controlled by placing Gelfoam over the injured sinus, necessitating additional techniques to control bleeding in the remaining patients. Out of the total patients, 20 were managed surgically, while two were managed conservatively due to a Glasgow Coma Scale (GCS) score of 3 and signs of brain death. Unique Contributions to Theory, Policy and Practice: The superior sagittal sinus was identified as the most commonly injured sinus. Road traffic accidents (RTAs) accounted for the most frequent cause of dural sinus injury, representing 40.9% of cases. Bleeding control proved more challenging when dealing with linear fractures parallel to the sinus or depressed (and/or penetrating) fractures over the sinus, compared to linear fractures crossing the sinus. The most significant factor influencing the mortality rate was the Glasgow Coma Scale (GCS) score on admission. Mortality and morbidity rates were highest in cases involving injury to the posterior part of the superior sagittal sinus, sigmoid sinuses, and combined injury to the anterior and middle parts of the superior sagittal sinus. Furthermore, the mortality rate was notably higher among military-injured patients than civilian-injured patients

Impact of perioperative factors on short-term outcomes after emergency surgery for acute traumatic extradural hematoma – A retrospective cohort study

BackgroundPreoperative clinical and imaging findings predict neurological outcomes in patients with traumatic brain injury (TBI). Similarly, intraoperative factors such as blood loss and hypotension can also affect outcomes. However, there is not much data regarding the influence of perioperative variables on clinical outcomes in patients with extradural hematoma (EDH). This study aimed to understand the effect of perioperative factors on short-term neurological outcomes in patients operated for acute traumatic EDH. MethodsAfter obtaining institutional ethical approval, we collected data retrospectively from records of patients who underwent emergency surgery for acute traumatic EDH over a two-year period. Data regarding age, gender, preoperative Glasgow coma scale (GCS) score, clinical and imaging findings, surgical and anesthetic details, blood loss and transfusion, duration of hospital stay, and GCS score at discharge were collected. Patients with discharge GCS score of 14–15 were considered to have favorable outcome and <14 as unfavorable outcome. Regression analysis was performed to examine the association between predictors and outcomes. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated. ResultsData of 501 patients were analyzed. Outcome was favorable in 343 (68.5 %) and unfavorable in 158 (31.5 %) patients. On multivariate logistic regression analysis (OR, 95 % CI, p value), age (1.03, 1.01–1.05, 0.01), preoperative GCS score (0.68, 0.61–0.76, <0.001), signs of basal skull fracture (1.9, 1.02–3.61, 0.043) and intraoperative blood loss (2.23, 1.2–4.16, 0.01) were independently associated with unfavorable outcome. Pneumonia, neurological deficits, inotrope use and duration of hospital stay was more in this group. ConclusionsOlder age, poor pre-operative GCS score, signs of basal skull fracture, and intraoperative blood loss were associated with lower discharge GCS score, increased neurological deficits and longer hospital stay in patients operated for acute traumatic EDH.

Utility of Pre-operative Glasgow Coma Scale and SKALE Scoring System to Predict need for Post-operative Ventilator Support in Intracranial Tumour Patients

Objective: To evaluate the feasibility of GCS and SKALE in predicting post-operative requirement of ventilator support in intracranial tumour patients. Methods: Seventy patients undergoing intracranial tumour resection surgery were assessed pre-operatively using GCS and SKALE scoring systems to predict their post-operative requirement of ventilator support. The data was analysed using SPSS software and ShapiroWilk test and Chi-Square tests were apllied to compare the obtain data. Results: The study included 70 patients, of whom 88.6% had good GCS of 13-15 and 72.9% had good SKALE score of &gt;8. We found that all patients with poor GCS ≤8 required post -operative ventilator support, while only 4 out 62 patients with GCS 13-15 required ventilator support post-operatively (p value &lt;0.05). Patients with SKALE score ≤8 also had higher incidence of post-operative ventilator requirement (31.6%) as against those with SKALE score &gt;8 (11.8%). Conclusion: GCS is a good predictor of post-operative ventilator requirement. SKALE scoring system requires further studies to prove its utility.

Analysis of Factors Affecting Outcome of Acute Extradural Hematoma—Our Observation in Dhaka Medical College and Hospital

Abstract Background Extradural hematoma (EDH) is a leading cause of death in young population. Timely intervention gives dramatic recovery but often fatal if not treated in time. The surgical outcome of EDH depends on many variables that strongly affect the prognosis of the disease, which are preoperative Glasgow coma scale (GCS), overlying skull fracture, time interval between injury and surgery, other associated intracranial injuries (like cerebral contusion, subdural hematoma, or intracerebral hematoma), pupillary abnormalities (anisocoria), and hematoma volume. But no correlation was found between surgical outcome of EDH and age, sex, etiology, and site of hematoma. Objective We want to identify the factors affecting the surgical outcome of EDH that will help us in preoperative prioritization of the cases for intervention, adequate resuscitation, and counselling the attendant regarding the outcome. Our ultimate goal was to reduce the mortality and morbidity from this disease. Methods This study was conducted on the patients admitted through neuroemergency and diagnosed as EDH by computed tomography scan of head, in the department of Neurosurgery of Dhaka medical college and hospital from January 1, 2017 to December 31, 2019. This is three-year prospective interventional study where all the patients underwent surgical evacuation of EDH on emergency basis and outcome was measured by Glasgow outcome scale (GOS) after 48 hours of admission and at discharge. Results Outcome was divided into good (GOS 4,5) and poor (GOS 1–3) groups. Pre-operative GCS, overlying skull fracture, time interval between injury and surgery, associated intracranial injuries, anisocoria and hematoma volume were the factors affecting the surgical outcome significantly. Conclusion Good surgical outcome is associated with EDH volume less than 40cc, preoperative GCS more than 8, absence of anisocoria, overlying skull fracture, no associated intracranial injury and surgery within 12 hours of injury. But age, sex and site of EDH has no definite correlation with outcome.

Clinical application of 3DSlicer and Sina in minimally invasive puncture drainage of elderly patients with spontaneous intracerebral hemorrhage under local anesthesia

BackgroundDecreased organ function and poor physical compensatory capacity in elderly patients diagnosed with spontaneous intracerebral hemorrhage (ICH) can make surgical treatment procedures challenging and risky. Minimally invasive puncture drainage (MIPD) combined with urokinase infusion therapy is a safe and feasible method of treating ICH. This study aimed to compare the treatment efficacy of MIPD conducted under local anesthesia using either 3DSlicer + Sina application or computer tomography (CT)–guided stereotactic localization of hematomas in elderly patients diagnosed with ICH. MethodsThe study sample included 78 elderly patients (≥ 65 years of age) diagnosed with ICH for the first time. All patients exhibited stable vital signs and underwent surgical treatment. The study sample was randomly divided into two groups, either receiving 3DSlicer+Sina or CT-guided stereotactic assistance. The preoperative preparation time; hematoma localization accuracy rate; satisfactory hematoma puncture rate; hematoma clearance rate; postoperative rebleeding rate; Glasgow Coma Scale (GCS) score after 7 days; and modified Rankin scale (mRS) score 6 months after surgery were compared between the two groups. ResultsNo significant differences in gender, age, preoperative GCS score, preoperative hematoma volume (HV), and surgical duration were observed between the two groups (all p-values > 0.05). However, the preoperative preparation time was shorter in the group receiving 3DSlicer + Sina assistance compared to that receiving CT-guided stereotactic assistance (p-value < 0.001). Both groups exhibited significant improvement in GCS scores and reduction in HV after surgery (all p-values < 0.001). The accuracy of hematoma localization and puncture was 100% in both groups. There were no significant differences in surgical duration, postoperative hematoma clearance rate, rebleeding rate, postoperative GCS and mRS scores between the two groups (all p-values > 0.05). ConclusionsA combination of 3DSlicer and Sina is effective in accurately identifying hematomas in elderly patients with ICH exhibiting stable vital signs, thus simplifying MIPD surgeries conducted under local anesthesia. This procedure may also be preferred over CT-guided stereotactic localization in clinical practice due to its ease of use and accuracy in hematoma localization.

The Swirl Sign and Its Relationship to Patient Outcomes in Extradural Hematomas: A Retrospective Investigation

Introduction:" Swirl sign" is a relatively uncommon sign, seen on non-contrast CT scans in patients with head trauma who develop extradural hematoma the prognostic significance of which is controversial. This research aims to evaluate the predictive significance of the swirl sign in patients with an extradural hemorrhage. Material and Methods: It was a retrospective study and included 145 patients, with traumatic brain injury, who underwent surgical treatment at the Department of Neurosurgery Holy Family Hospital, Rawalpindi, Pakistan, between January 2022 and January 2023 and had traumatic EDH identified by computed tomography scan. Patients who did not undergo surgery or had combined or open craniocerebral injuries were eliminated. A Glasgow Outcome Scale score was used to evaluate outcomes after three months of traumatic brain injury. Mann-Whitney U test, the Chi-square test, and multivariate logistic regression were applied for descriptive and inferential analysis. Results: A total of 145 cases were evaluated, 19 (13.1%) demonstrated the sign on a CT scan of the brain. Analysis displayed a notable association between the incidence of the swirl sign and pupillary size, preoperative Glasgow Coma Scale score, time between trauma and first CT scan, and volume of hematoma measured intraoperatively. Patients displaying the swirl sign showed an increased mortality rate (25%) compared to patients without the swirl sign (5%) and worse outcomes at 3 months. Conclusion: The presence of the swirl sign on the CT scan had a significant association with worse outcomes. Early detection and prompt surgical evacuation are important for patients with this sign.

Mortality of Surgically Treated Neurotrauma in Elderly Patients and the Development of a Prediction Score: Geriatric Neurotrauma Mortality Score

As the population worldwide is aging, the need for surgery in elderly patients with neurotrauma is increasing. The aim of this study was to compare the outcome of elderly patients undergoing surgery for neurotrauma with younger patients and to identify the risk factors for mortality. We retrospectively analyzed consecutive patients undergoing craniotomy or craniectomy for neurotrauma at our institution from 2012 to 2019. Patients were divided into two groups (≥70 years or <70 years) and compared. The primary outcome was the 30-day mortality rate. Potential risk factors for 30-day mortality were assessed in a uni- and multivariate regression model for both age groups, forming the basis of a 30-day mortality prediction score. We included 163 consecutive patients (average age 57.98 ± 19.87 years); 54 patients were ≥70 years. Patients ≥70 years showed a significantly better median preoperative Glasgow Coma Scale (GCS) score compared with young patients (P < 0.001), and fewer pupil asymmetry (P= 0.001), despite having a higher Marshall score (P= 0.07) at admission. Multivariate regression analysis identified low pre- and postoperative GCS scores and the lack of prompt postoperative prophylactic low-molecular-weight heparin treatment as risk factors for 30-day mortality. Our score showed moderate accuracy in predicting 30-day mortality with an area under the curve of 0.76. Elderly patients after neurotrauma present with a better GCS at admission despite having more severe radiographic injuries. Mortality and favorable outcome rates are comparable between the age groups.

Outcomes of decompressive craniectomy for large territory cerebral infarction with and without prior reperfusion: a multicentre retrospective review.

Reperfusion therapy has greatly improved outcomes of ischaemic stroke but remains associated with haemorrhagic conversion and early deterioration in a significant proportion of patients. Outcomes in terms of function and mortality are mixed and the evidence for decompressive craniectomies (DC) in this context remains sparse. We aim to investigate the clinical efficacy of DC in this group of patients compared to those without prior reperfusion therapy. A multicentre retrospective study was conducted between 2005 and 2020, and all patients with DC for large territory infarctions were included. Outcomes in terms of inpatient and long-term modified Rankin scale (mRS) and mortality were assessed at various time points and compared using both univariable and multivariable analyses. Favourable mRS was defined as 0-3. There were 152 patients included in the final analysis. The cohort had a mean age of 57.5years and median Charlson comorbidity index of 2. The proportion of preoperative anisocoria was 15.1%, median preoperative Glasgow coma scale was 9, the ratio of left-sided stroke was 40.1%, and ICA infarction was 42.8%. There were 79 patients with prior reperfusion and 73 patients without. After multivariable analysis, the proportion of favourable 6-month mRS (reperfusion, 8.2%; no reperfusion, 5.4%) and 1-year mortality (reperfusion, 26.7%; no reperfusion, 27.3%) were similar in both groups. Subgroup analysis of thrombolysis and/or thrombectomy against no reperfusion was also unremarkable. Reperfusion therapy prior to DC performed for large territory cerebral infarctions does not affect the functional outcome and mortality in a well-selected patient population.
