Epidural Hematoma Following Lumbar Puncture in a Child with Pycnodysostosis and Intracranial Hypertension: A Case Report

Abstract Pycnodysostosis (PDO) is a rare genetic skeletal dysplasia. Due to its rarity and clinical heterogenicity, information about its uncommon features and complications is limited. One such complication is intracranial hypertension (IH), which can be managed acutely through lumbar drainage of cerebrospinal fluid (CSF). In this report, we present the case of a 12-year-old boy with known PDO and IH who presented with worsening headache and dizziness and underwent a therapeutic lumbar puncture (LP). Two days after the LP, he experienced increasing headache and nausea. A brain computed tomography (CT) scan revealed a left frontal epidural hematoma (EDH). He was managed expectantly, and a follow-up CT scan confirmed hematoma resolution. This case presents IH as a rare complication of PDO and presents an instance where an EDH developed following an LP, which is a rare occurrence. We conclude that if LP is considered for such patients, physicians should be vigilant for the possible occurrence of intracranial hemorrhage.

Leakage Sign Is a Reliable Predictor of Hematoma Expansion in Acute Epidural Hematoma

Hematoma expansion (H-Ex) in small-/medium-sized acute epidural hematoma (AEDH) cases upon emergency admission is critical. Predicting H-Ex can lead to early surgical interventions, improving outcomes, and eliminating the need to check for expansion via computed tomography (CT). This study aimed to identify the most reliable predictors of AEDH expansion. We retrospectively collected data from patients with pure AEDH not requiring surgical treatment upon emergency admission from 2012 to 2022. We assessed clinical and laboratory data, time from injury to the first CT, and time to follow-up CT. Factors predictive of H-Ex on the second follow-up CT, including the leakage sign (LS), were analyzed. A total of 23 patients with pure AEDH without surgery at admission were included, and LS was positive in 18. Thirteen patients showed H-Ex. The H-Ex group showed a significantly higher rate of positive LS and a lower mean platelet count than the group without H-Ex. LS's predictive value for AEDH expansion showed 100% sensitivity and 50% specificity. All patients with negative LS and normal platelet counts showed no H-Ex. Analyzing the time from injury to the first CT suggested that LS (+) within 120minutes strongly predicted H-Ex. Reconstructed three-dimensional images of the leakage point on the skull revealed multiple mottled bleeding points on the dural surface. LS can predict H-Ex in patients with pure AEDH for whom emergency surgery is unnecessary at admission. The time from injury and platelet counts must also be considered.

Clinical outcome after surgical management of spontaneous spinal epidural hematoma

PurposeSpontaneous spinal epidural hematoma (SSEH) is a rare pathology characterized by a hemorrhage in the spinal epidural space without prior surgical or interventional procedure. Recent literature reported contradictory findings regarding the clinical, radiological and surgical factors determining the outcome, hence the objective of this retrospective analysis was to re-assess these outcome-determining factors.MethodsPatients surgically treated for SSEH at our institution from 2010 – 2022 were screened and retrospectively assessed regarding management including the time-to-treatment, the pre-and post-treatment clinical status, the radiological findings as well as other patient-specific parameters. The outcome was assessed using the modified McCormick Scale. Statistical analyses included binary logistic regression and Fisher’s exact test.ResultsIn total, 26 patients (17 men [65%], 9 women [35%], median age 70 years [interquartile range 26.5]) were included for analysis. The SSEHs were located cervically in 31%, cervicothoracically in 42% and thoracically in 27%. Twenty-four patients (92%) improved after surgery. Fifteen patients (58%) had a postoperative modified McCormick Scale grade of I (no residual symptoms) and 8 patients (31%) had a grade of II (mild symptoms). Only 3 (12%) patients remained with a modified McCormick Scale grade of IV or V (severe motor deficits / paraplegic). Neither time-to-treatment, craniocaudal hematoma expansion, axial hematoma occupation of the spinal canal, anticoagulation or antiplatelet drugs, nor the preoperative clinical status were significantly associated with the patients’ outcomes.ConclusionEarly surgical evacuation of SSEH generally leads to favorable clinical outcomes. Surgical hematoma evacuation should be indicated in all patients with symptomatic SSEH.

Predictive Factors for Regression versus Progression of Nonevacuated Posttraumatic Acute Extradural Hematoma.

Study Design This study was a retrospective study conducted from October 2020 to October 2022 on 106 posttraumatic patients with acute extradural hematomas (EDHs) who were initially planned for conservative treatment. 74 patients had spontaneous EDH regression (EDHR), while 32 patients developed EDH progression (EDHP) and were shifted for surgery. The two groups were statistically compared regarding the different demographic, clinical, and radiographic factors to identify the significant predictors for regression versus progression of acute posttraumatic EDH. Objectives Conventionally, urgent evacuation is the accepted management for EDH. However, several recent reports have described successful conservative management in selected patients. There are no adequate clues to verify patients who will have spontaneous EDHR from those at risk for EDHP and delayed surgery. The main objective of this study was to identify the significant predictors for possible regression versus progression of acute posttraumatic EDH initially planned for nonsurgical treatment. Materials and Methods A retrospective study conducted over 2 years, included 106 head trauma patients with acute EDH, who were admitted to our department and were initially planned for conservative treatment. Various demographic, clinical, and radiographic factors were analyzed to verify the significant predictors for spontaneous EDHR (EDHR group) versus EDHP and subsequent surgical evacuation (EDHP group). Results The mean age was 20.37 ± 12.712 years and the mean Glasgow Coma Scale score (GCS) was 12.83 ± 2.113. Total 69.8% of patients showed spontaneous EDHR, while 30.2% developed EDHP and were shifted for surgical evacuation. Statistical comparison showed that higher GCS ( p = 0.002), frontal location ( p = 0.022), and concomitant fissure fracture ( p = 0.014) were the significant predictors for EDHR, while younger age ( p = 0.006), persistent nausea/vomiting ( p = 0.046), early computed tomography (CT) after trauma ( p = 0.021), temporal location ( p < 0.001), and coagulopathy ( p = 0.001) were significantly associated with EDHP. Conclusion Patients with traumatic EDH fitting the criteria of initial nonsurgical treatment necessitates 48 hours of close observation and serial CT scans at 6, 12, 24, and 48 hours to confirm the regression or early detect the EDHP. Patients with high GCS, frontal hematomas, and associated fissure fracture are at low risk for EDHP. Increased alertness is mandatory for young age and patients with persistent nausea/vomiting, early CT scan, temporal hematomas, or coagulopathy.

Acute synchronous bilateral extradural hematoma, a scarcely reported, rare entity

Objective: Extradural hematomas (EDHs) are contact injuries resulting from blunt trauma to the skull. It may be unilateral or bilateral. Bilateral acute extradural hematoma (EDH) was rarely reported before the advent of computed tomography. Mortality rates vary from 10.0%-40.0% and are an index of alertness and efficiency of health care and hospital set-up. EDH is an injury with preventable mortality in most cases. Bilateral acute extradural hematomas no longer confer high mortality of pre-CT era because of early diagnosis on CT, and prompt neurosurgical intervention. We present our experience with Bilateral EDH cases with an aim to investigate clinical, GCS score, and radiological features and also to analyse outcomes in these patients. Material and methods: We analyzed cases of EDH who presented at our centre from January 2023 to December 2023 and further investigated ten cases of bilateral EDH. All the patients were examined clinically and a plain computerized tomography scan of the head was performed. The clinical details of all patients, GCS at admission and discharge, radiological findings on CT and neurosurgical intervention performed, and GOS (Glasgow outcome score) were noted. Results: Road traffic accident was the reason for traumatic brain injury in all the cases. The GCS at admission was between 13–15 in 2 patients, 8–12 in 6 and 3–7 in 2 patients. Bilateral EDH was found in all of our patients .9 out of 10 cases were males. On CT head underlying fracture was seen in all cases. The localization of epidural hematomas in CT scans was bifrontal in four of the cases. All cases were treated with surgical management. The GOS Score was 5 in eight of the patients. Conclusion: Posttraumatic bilateral acute extradural hematoma is a rare entity, but now does not show the high mortality previously seen in the preCT era. This is due to early radiological diagnosis on CT and profuse monitoring combined with expeditious operative procedures.

Epidural Blood Patch in Subdural Hematoma Due to Spontaneous Intracranial Hypotention: A Case Report and Literature Review

Spontaneous intracranial hypotension (SIH) is an orthostatic headache syndrome with variable symptoms and complications which is often misdiagnosed at initial manifestations. SIH results from spontaneous CSF leakage leading to brain sag. The typical findings on cranial MR imaging consist of subdural fluid collections, enhancement of the pachymeninges, engorgement of venous structures, pituitary hyperemia, and sagging of the brain. Subdural hematoma may occur as a result of tearing of bridging veins and usually develop into chronic subdural hematoma. The majority of patients with SDH due to SIH have chronic DSH and, therefore, rarely present with neurological deficits. Evacuation of SDH may be performed for large SDH with ME (mass effects), or when dilated or asymmetric pupil is present. However in most cases, evacuation of the hematoma is not necessary and may result in worsened outcomes. The epidural blood patch (EBP) is a treatment of choice. Fortunately, most of these subdural hematomas can be handled with treatment directed at the underlying spinal CSF leak without the need for surgery. We report the case of 42-year-old man with the chief complaint of orthostatic headache. He was admitted to neurology ward and after imaging studies, it was found that he has bilateral subdural hematoma. Due to the lack of history of trauma, underlying disease, and coagulation disorder, and considering the imaging findings, the patient was referred to the pain department to perform an epidural blood patch. After performing the epidural blood patch, the patient's pain was relieved immediately, and during a three-month follow-up period, the epidural hematoma was completely absorbed. Spontaneous intracranial hypotension (SIH) is a highly misdiagnosed and underdiagnosed disorder and requires a high index of suspicion for diagnosis. During the last decades, a much larger number of spontaneous cases are identified. Literature is a bit confusing, with some authors recommending evacuation of subdural fluid in cases of deteriorating consciousness and few others recommending EBP first even in patients with comatose state but epidural patch is often an important part of treatment.

The safety of perioperative antiplatelet continuation without selection biases in microsurgical decompression surgery for single level lumbar spinal stenosis and lumbar disc herniotomy.

Each institution or physician has to decide on an individual basis whether to continue or discontinue antiplatelet (AP) therapy before spinal surgery. The purpose of this study was to determine if perioperative AP continuation is safe during single-level microsurgical decompression (MSD) for treating lumbar spinal stenosis (LSS) and lumbar disc hernia (LDH) without selection bias. Patients who underwent single-level MSD for LSS and LDH between April 2018 to December 2022 at our institute were included in this retrospective study. We collected data regarding baseline characteristics, medical history/comorbidities, epidural hematoma (EDH) volume, reoperation for EDH, differences between preoperative and one-day postoperative blood cell counts (ΔRBC), hemoglobin (ΔHGB), and hematocrits (ΔHCT), and perioperative thromboembolic complications. Patients were divided into two groups: the AP continuation group received AP treatment before surgery and the control group did not receive antiplatelet medication before surgery. Propensity scores for receiving AP agents were calculated, with one-to-one matching of estimated propensity scores to adjust for patient baseline characteristics and past histories. Reoperation for EDH, EDH volume, ΔRBC, ΔHGB, ΔHCT, and perioperative thromboembolic complications were compared between the groups. The 303 enrolled patients included 41 patients in the AP continuation group. After propensity score matching, the rate of reoperation for EDH, the EDH volume, ΔRBC, ΔHGB, ΔHCT, and perioperative thromboembolic complication rates were not significantly different between the groups. Perioperative AP continuation is safe for single-level lumbar MSD, even without biases.

Usefulness and Safety of Gelatin-Thrombin Matrix Sealants in Minimally Invasive Microscopic Discectomy.

Objective This study aimed to evaluate the usefulness and safety of gelatin-thrombin matrix sealants (GTMSs) in minimally invasive microscopic discectomy, a surgical procedure commonly used to treat lumbar disc herniation. Materials and Methods Out of 484 patients who underwent minimally invasive microscopic discectomy between April 2018 and December 2022, 35 patients with a history of surgery at the same level were excluded, resulting in a total of 449 patients included in the study. Among them, 316 patients were treated using GTMS, whereas 133 were treated using collagen-based absorbable local hemostatic agents. Patient characteristics, surgical duration, intraoperative blood loss, postoperative drainage volume, intraoperative dural injury, and incidence of postoperative epidural hematoma were analyzed and compared between the two groups. Results No significant differences in patient demographics were observed between the two groups, except for activated partial thromboplastin time and prothrombin time. Although there were no significant differences in the mean surgical time and intraoperative blood loss between the two groups, they tended to be shorter and less in the GTMS group (56.3 ± 20.2 vs. 58.2 ± 20.4 minutes [ p = 0.36] and 10.0 ± 15.4 vs. 11.8 ± 8.3 g [ p = 0.20]). The volume of postoperative drainage was significantly lower in the GTMS group than that in the comparison group (35.3 ± 21.8 vs. 49.5 ± 34.1 g [ p < 0.01]). There was a trend indicating a difference in the number of intraoperative dural injuries and the need for reoperation due to postoperative epidural hematoma (2 vs. 3 ± 20.4 minutes [ p = 0.21] and 1 vs. 2 [ p = 0.16]). Conclusion The use of a GTMS in minimally invasive microscopic discectomy appears to be beneficial in reducing postoperative drainage volume. It has also been shown that it may improve clinical outcomes such as intraoperative dural injury and postoperative epidural hematoma. Furthermore, further consideration of the medical economic impact is required.

Optimal Ensemble Transfer Learning Espoused Detection and Classification of Intracranial Haemorrhage

The injury of blood vessels in brain tissues known as intracranial haemorrhage (ICH) is a major cause of stroke. Computed tomography (CT) and X-ray images are frequently used to estimate the location and size of haemorrhages. Radiologists segment CT scan pictures manually using planimetry, which takes a lot of time. To overcome this issue, an optimal ensemble transfer learning espoused detection and classification of intracranial haemorrhage (CIH-V16-V19-R50-DN121-IV3-XN) is proposed in this paper. Initially, the images are gathered via the Radiological Society of North America (RSNA) ICH dataset. Afterwards, the images are fed to pre-processing. The pre-processed output is fed into a classification segment. The model used for classification is the ensemble transfer learning model such as VGG16, VGG19, Resnet50, InceptionV3, Desnet121, and XceptionNet. With the help of ensemble transfer learning techniques, the image is classified into subdural haemorrhage, epidural haemorrhage, subarachnoidal haemorrhage, intraventricular haemorrhage, intraparenchymal haemorrhage, and normal. With the help of voting classifier the best learning model with accuracy is identified. The proposed CIH-V16-V19-R50-DN121-IV3-XN algorithm is implemented in MATLAB using dataset of the RSNA ICH dataset. The performance metrics, such as accuracy, precision, sensitivity, F1-score, specificity, ROC, and error rate, are examined to analyse the efficiency of the proposed method. The performance of the CIH-V16-V19-R50-DN121-IV3-XN approach attains 10.12%, 22.33%, 21.45% high accuracy and 10.09%, 13.65%, 29.87% high specificity compared to the existing methods.

Traumatic Delayed Posterior Cranial Fossa Epidural Hematoma: A Rare Entity

AbstractPosterior fossa epidural hematomas (EDHs) are much rarer entities than supratentorial EDHs which are reported only 4 to 7% in the literature. Due to the tight space and critical structures in posterior fossa, only a few cases can go with the conservative management but even then patients can deteriorate anytime with enlargement of hematoma and compression effects on brain stem and require urgent evacuation. This letter aims to provide a case of a young kid who presented initially with less-volume EDH and later required urgent evacuation because of hematoma expansion.

Impact of Time from Injury to Surgery on Postoperative Functional Recovery in Large Volume Traumatic Extradural Hematomas

Abstract Background In traumatic brain injury (TBI) patients, the time from trauma to cranial surgery is always of great concern to patients and neurosurgeons. Patients and Methods A retrospective study conducted on 93 TBI patients presented with Glasgow Coma Scale from 4 to 13 and were operated for large volume (≥ 40 cm3) extradural hematoma (EDH) from July 2020 to December 2022. Surgery was done either within 6 hours following trauma (group A) or later than 6 hours (group B). We evaluated the impact of time from injury to surgery on postoperative clinical recovery, survival, and hospital stay. Results Fifty patients (53.8%) were operated upon within 6 hours after trauma and 43 patients (46.2%) had operations later than 6 hours. No significant difference was found between the two study groups regarding any of the preoperative clinical or radiological factors except for the mean time from injury to surgery (p &lt; 0.001). Delayed surgery &gt; 6 hours was significantly associated with higher postoperative mortality (p = 0.014). Hospital stay was significantly shorter in patients operated ≤ 6 hours (p = 0.006). Patients operated ≤ 6 hours showed significantly favorable functional recovery both at discharge (p = 0.010) and after 1 month of follow-up (p = 0.023). Conclusion Timely surgical intervention for large volume traumatic EDH is the gold standard. Early surgery “within 6 hours from trauma” not only can save patients' life but also is significantly associated with postoperative favorable clinical recovery, low morbidity, and short hospital stay.

Middle Meningeal Arterial Embolization Combined With Drilling in the Treatment of Acute Epidural Hematoma.

The purpose of this study was to determine the technical feasibility and safety of middle meningeal arterial (MMA) embolization combined with drilling drainage in the treatment of acute epidural hematoma (AEDH) by comparing it with traditional craniotomy in the treatment. One hundred seventeen patients with AEDH treated for MMA embolization combined with drilling and drainage or craniotomy hematoma removal from January 2017 to September 2020 were retrospectively analyzed and divided into a craniotomy group (n=85) and a minimally invasive group (n=32). Hematoma removal was performed in the craniotomy group, and MMA embolization combined with drilling and drainage was performed in the minimally invasive group. The general clinical data, imaging data, surgery, and follow-up of the 2 groups were compared and analyzed. Compared with the craniotomy group, the residual hematoma volume in the minimally invasive group was higher than in the craniotomy group. The average postoperative drainage duration in the minimally invasive group was longer than in the craniotomy group. Compared with the craniotomy group, the minimally invasive group was associated with shorter operative time, less intraoperative bleeding, and lower rates of postoperative rebleeding. In addition, the incidence of postoperative complications and length of hospitalization in the minimally invasive group were significantly shortened. Middle meningeal arterial embolization combined with drilling and drainage in the treatment of AEDH caused by MMA active bleeding is safe, effective, and more minimally invasive, and can be promoted and applied.

Intracranial hemorrhage in glioblastoma: Incidence, risk factors, and outcome.

2074 Background: The incidence and clinical implications of intracranial hemorrhage (ICH) in patients with glioblastoma have not been well studied. Risk factors for ICH and associations with therapy and outcome remain unknown. It has been speculated that prior radiotherapy, chemotherapy-associated thrombocytopenia, steroid medications as well as age, other comedications and comorbidities contribute to the risk of ICH in this patient population. Methods: We identified consecutive patients with glioblastoma per WHO 2021 definition from the electronic charts of the University Hospital in Zurich, Switzerland and explored the incidence, putative risk factors, management and outcome of ICH in patients with glioblastoma. ICH was identified on central MRI and imaging report review. The study has been approved by Swissethics (2023-00532). Results: Among 387 patients diagnosed between 2010 and 2019, 6 patients presented with ICH, and 22 patients experienced ICH in the further disease course, after a median time of 153 days (IQR 79-323 days). Of the 6 patients with ICH at diagnosis, 2 patients were on anti-platelet agents and 1 was on anticoagulation. ICH occurred in the tumor region in all these patients. There were no specific features in their history compared with patients that did not present with ICH at diagnosis. Among 22 patients with ICH after diagnosis, 9 patients (41%) experienced ICH prior to first progression. ICH were not restricted to the tumor region, but included subdural hematomas in 7 patients and an epidural hematoma in one patient. Fifteen patients (68%) were hospitalized for ICH, and 5 patients (23%) had a craniotomy. Thirteen patients (59%) had no change in management, 4 patients (18%) started a new intervention, and 5 patients (23%) went to palliative care. Compared with patients without any ICH ever documented, the 28 patients with ICH were more often male, but not older, did not have a history of arterial hypertension, diabetes, chronic kidney disease or smoking, and did not have larger tumors at diagnosis. At the timepoint of intracranial hemorrhage, six patients (27%) had been preexposed to bevacizumab, yet, 188 patients (53%) of the reference cohort received bevacizumab across the disease trajectory without experiencing an ICH. Three patients (14%) had platelet counts below 100,000/µl. Overall survival in the 28 patients who experienced an ICH was not inferior to survival in the population of patients without an ICH. Conclusions: ICH at diagnosis is rare in glioblastoma and its etiology remains to be identified. It may be related to intrinsic features of the tumor and its blood vessels since no other patient-related risk factors were identified. Overall, male sex was the only risk factor associated with ICH in this study, but ICH does not signify a poor outcome overall.

Fecal microbiota transplantation in patients with spinal cord injury with recurrent Clostridioides difficile infection: a case report

Objective: Fecal microbiota transplantation (FMT) is an emerging treatment for Clostridioides difficile infection (CDI) through reconstruction of the gut microbiota, but its impact in people with spinal cord injury (PWSCI) is limited. The aim of this paper is to report the use of FMT in a PWSCI with CDI. Methods: The FMT was conducted on October 30, 2019. Results: A 72-year-old man with T8 complete paraplegia from compression of the spinal cord due to an epidural hematoma was referred. He has known severe pancreatic enzyme insufficiency, malabsorption, and a history of recurrent CDI. Despite intensive dietetic treatment (probiotics, enteral nutrition, and parenteral nutrition), and multiple courses of antibiotics (vancomycin and fidaxomicin at various doses and durations) for CDI, he continued to be CDI-positive. His CDI was successfully treated after 2 colonoscopically delivered FMTs. At the 24-month follow-up, he remains CDI-negative and reports improved independence. Although there has been considerable variability in the criteria for the FMT and its mode of delivery, FMT can be an option to treat recurrent CDI. Conclusion: This case report reports a PWSCI with recurrent CDI who has been successfully treated with FMT and remains in long-term remission. It supports the consideration of FMT in PWSCI with CDI when antibiotic treatment has been unsuccessful.

An unusual case of remitting and relapsing intraspinal epidural hamartoma with hemorrhage

Spinal epidural hematoma is a rare disease and is most commonly idiopathic. Other common causes are vascular malformations, coagulopathy, hypertension, surgery, and trauma. Epidural vascular hamartoma associated with hemorrhage is a less known entity. We report an unusual case of epidural vascular hamartoma associated with hemorrhage resulting in back pain and neurological deficits. A distinctive feature of this case was waxing and waning signs and symptoms with evidence of radiological resolution of the lesion in the phase of remission.

Surgical Outcomes of Epidural Hematoma in Trauma Patients with Absent Pupillary Reactions: A National Trauma Data Analysis.

Absent pupillary reaction occasionally heralds a poor prognosis following severe head injury. The purpose of the study was to evaluate the outcome of all patients who underwent acute evacuation of epidural hematoma (EDH) despite absent bilateral pupillary reaction. The Trauma Quality Improvement Program (TQIP) database for the calendar years 2017 and 2018 was accessed for the study. Adult patients ≥18 years of age who sustained severe traumatic brain injury (TBI) with the diagnosis of EDH and underwent evacuation of the hematoma were included in the study. The patients' characteristics, injury severity score (ISS), Glasgow Coma Scale (GCS) score, midline shift, and comorbidities were compared between patients who had absence of both pupillary reaction (ABPR) and those who presented with presence of both pupillary reaction (PBPR). The primary outcome of the study was in-hospital mortality. Propensity score matching analyses were performed for the study. No significant differences were found between the ABPR and PBPR groups regarding the median age (37 years [interquartile range (IQR): 26-53] vs. 40 years [IQR: 28-55]), gender (males; 81.9 vs. 79.5%), median ISS (29 [25.5-34] vs. 27 [25-33]), GCS score (3 [3-4] vs. 3 [3-3], presence of significant midline shift (75.9 vs. 79.5%), and comorbidities. The patients who presented with ABPR had a significantly higher mortality (34.9 vs. 10.8%; p = 0.002). A higher number of patients were discharged to skilled nursing and rehabilitation facilities (16.7 vs. 10.8% and 46.3 vs. 41.9%, respectively; p = 0.045). Approximately 65% of severe TBI patients survived after the evacuation of the EDH despite the absence of pupillary reaction.

Prevención de eventos trombóticos en pacientes sometidos a cirugía de artrodesis lumbar por vía posterior: experiencia en nuestro centro. Estudio retrospectivo de casos

There is no generalized consensus regarding perioperative prophylaxis of venous thromboembolism (VTE), either on using or timing it in patients undergoing spine surgery. VTE is a current concern because, even though being an uncommon event, it can cause serious complications. The aim of the present study is to propose guidelines for the prevention of thrombotic events in posterior spinal surgery, either as deep vein thrombosis or pulmonary thromboembolism. If the number of patients getting prophylaxis drugs is reduced a subsequent reduction of the incidence of epidural hematoma can be expected. A number of 235 patients who had undergone posterior spinal arthrodesis in the previous five years were studied. Mechanical thromboprophylaxis measures consisting of compression stockings were applied in all of them. Anticoagulant drugs were also applied whenever risk factors for thrombosis were observed. Early weight-bearing was resumed immediately after surgery. Demographic, clinical, and surgical variables were collected, as well as complications appearing during the follow-up period, that was scheduled at one, two, four, six and twelve months after the surgery. Thrombotic events, if present, were diagnosed by clinical and imaging tests such as ultrasound and CT angiography. From the total 235 patients of this series, one hundred and fifty-three cases met the study inclusion criteria. A total of four thrombotic events appeared, one in the form of deep vein thrombosis and other three in the form of pulmonary thromboembolism. These last patients suffering an embolism died because of it. None of the variables studied had statistical significance for the occurrence of a thrombotic event. All four patients who suffered thrombotic events were receiving anticoagulant drugs, in addition to mechanical compression stockings, because of the presence of risk factors for thrombosis. By applying the fore mentioned protocol, adequate prevention of thromboembolic events was achieved in this study population of patients undergoing posterior spinal surgery.

Clinical Evaluation of Dural (Spinal) Membrane Repair Materials

To select high-quality and cost-effective dural (spinal) membrane repair materials, in order to reduce the cost of consumables procurement, save medical insurance funds, and optimize hospital operation and management. Taking the BS06B disease group (spinal cord and spinal canal surgery without extremely severe or severe complications and comorbidities, mainly diagnosed as congenital tethered cord syndrome) as an example, a retrospective analysis was conducted on the relevant data of surgical treatment for congenital tethered cord syndrome conducted in our hospital from January 2021 to June 2023. Safety and efficacy indicators in clinical application (incidence of postoperative epidural hemorrhage, incidence of postoperative purulent cerebrospinal meningitis, incidence of cerebrospinal fluid leakage, surgical duration, and postoperative hospital stay) were compared. There was no difference in safety and effectiveness between different brands of dura mater repair materials. For the repair of small incisions in dura mater surgery, high-quality and cost-effective dura mater repair materials can be selected to reduce hospital costs and control expenses for the disease group.
