Crystalloid volume versus catecholamines for management of hemorrhagic shock during esophagectomy - assessment of microcirculatory tissue oxygenation of the gastric conduit in a porcine model using hyperspectral imaging - an experimental study.

Oncologic esophagectomy is a two-cavity procedure with considerable morbidity and mortality. Complex anatomy and the proximity to major vessels constitute a risk for massive intraoperative hemorrhage. Currently, there is no conclusive consensus on the ideal anesthesiologic countermeasure in case of such immense blood loss. The objective of this work was to identify the most promising anesthesiologic management in case of intraoperative hemorrhage with regards to tissue perfusion of the gastric conduit during esophagectomy using hyperspectral imaging (HSI). An established live porcine model (n=32) for esophagectomy was used with gastric conduit formation and simulation of a linear stapled side-to-side esophagogastrostomy. After a standardized procedure of controlled blood loss of about 1 L per pig, the four experimental groups (n=8 each) differed in anesthesiologic intervention i.e. (I) permissive hypotension, (II) catecholamine therapy using noradrenaline, (III) crystalloid volume supplementation and (IV) combined crystalloid volume supplementation with noradrenaline therapy. HSI tissue oxygenation (StO2) of the gastric conduit was evaluated and correlated with systemic perfusion parameters. Measurements were conducted before (T0) and after (T1) laparotomy, after hemorrhage (T2) and 60 minutes (T3) and 120 minutes (T4) after anesthesiologic intervention. StO2 values of the gastric conduit showed significantly different results between the four experimental groups with 63.3% (±7.6%) after permissive hypotension (I), 45.9% (±6.4%) after catecholamine therapy (II), 70.5% (±6.1%) after crystalloid volume supplementation (III) and 69.0% (±3.7%) after combined therapy (IV). StO2 values correlated strongly with systemic lactate values (r=-0.67; CI -0.77 to -0.54), which is an established prognostic factor. Crystalloid volume supplementation (III) yields the highest StO2 values and lowest systemic lactate values and therefore appears to be the superior primary treatment strategy after hemorrhage during esophagectomy with regards to microcirculatory tissue oxygenation of the gastric conduit.

Prediction of hemorrhage in placenta previa: Radiomics analysis of pelvic MRI images

IntroductionPrediction of intraoperative massive hemorrhage is still challenging in placenta previa. Radiomics analysis has been investigated as a new evaluation method for analyzing medical images. We used radiomics analysis on placental magnetic resonance imaging (MRI) images to predict intraoperative hemorrhage in placenta previa. MethodsWe used the sagittal MRI T2-weighted sequence in placenta previa. Using the rectangular region from the uterine os to the anterior wall, we extracted 97 radiomics features. We also collected patient demographics and blood test data as clinical variables. Combining these radiomics features and clinical variables, logistic regression models with a stepwise method were built to predict the risk of hemorrhage, defined as blood loss of > 2000 ml. We evaluated the prediction performance of the models using accuracy and area under the curve (AUC), also analyzing the important variables for the prediction by stepwise methods. ResultsWe enrolled a total of 63 placenta previa cases including 30 hemorrhage cases from two institutes. The model combining clinical variables and radiomics features showed the best prediction performance with an accuracy of 0.70 and an AUC of 0.69 in the internal validation data, and accuracy of 0.41 and an AUC of 0.70 in the external validation data, compared with human experts (accuracy of 0.62). Regarding variable selection, two radiomics features. ’original_glrlm_LowGrayLevelRunEmphasis,’ and ’diagnostics_Image-original_Minimum,’ were important predictors for hemorrhage by the stepwise method. DiscussionRadiomics features based on MRI could be used as effective predictive variables for hemorrhage in placenta previa. Radiomics analysis of placental imaging could lead to further analysis of quantitative variables related to obstetric diseases.

Risk factors of bleeding during rectal cancer surgery in obese patients in Japan.

According to several clinical trials for patients with rectal cancer, laparoscopic surgery significantly reduces intraoperative complications and bleeding compared with laparotomy and demonstrated comparable long-term results. However, obesity is considered one of the risk factors for increased surgical difficulty, including complication rate, prolonged operation time, and bleeding. Patients with clinical pathological stage II/III rectal cancer and a body mass index of ≥25 kg/m2 who underwent laparotomy or laparoscopic surgery between January 2009 and December 2013 at 51 institutions participating in the Japan Society of Laparoscopic Colorectal Surgery were included. These patients were divided into major bleeding (>500 mL) group and minor bleeding (≤500 mL) group. The risk factors of major bleeding were evaluated by univariate and multivariate analyses. This study included 517 patients, of which 74 (19.9%) experienced major bleeding. Patient characteristics did not significantly differ between the two groups. The major bleeding group had a longer operative time (p < 0.001) and a larger tumor size than the minor bleeding group (p = 0.011). In the univariate analysis, age >65 years, laparotomy, operative time >300 min, and multivisceral resection were significantly associated with intraoperative massive bleeding. In the multivariate analysis, age >65 years (odds ratio [OR], 2.29; 95% confidence interval [CI], 1.13-4.82), laparotomy (OR, 20.82; 95% CI, 11.56-39.75), operative time >300 min (OR, 5.39; 95% CI, 1.67-132), and multivisceral resection (OR, 10.72; 95% CI, 2.47-64.0) showed to be risk factors for massive bleeding. Age >65 years, laparotomy, operative time >300 min, and multivisceral resection were risk factors for massive bleeding during rectal cancer surgery in patients with obesity.

Aesthetic Mandibular Angloplasty to Improve Patient Quality of Life in Chronic Recurrent Multifocal Osteomyelitis

Summary: Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoimmune disease that typically develops during adolescence and primarily affects women. CRMO primarily targets the bone in arms and legs, with sporadic occurrences in the mandible. CRMO is typically managed with medical treatment, and the efficacy of surgery remains controversial. Complications of surgery include massive bleeding and potential flare-up of CRMO symptoms. Herein, we report a patient with CRMO who had lesions in the bilateral rami of the mandible treated with aesthetic mandibular angloplasty. This is the first case of aesthetic mandibular angloplasty in a patient with CRMO who had bilateral rami involvement of the mandible. The patient began experiencing jaw pain accompanied by swelling and throbbing discomfort beneath the jawline at the age of 10. A pediatrician diagnosed CRMO, and the symptoms were controlled with nonsteroidal antiinflammatory drugs and immunosuppressants (infliximab, adalimumab). Aesthetic mandibular angloplasty was performed at our center because of mandibular hypertrophy. This procedure necessitated considerable removal of the spongy bone, raising concerns about potential massive intraoperative bleeding. Approximately 1.5 cm of the mandibular body was excised to reveal the cortical bone. Bleeding during surgery was not severe, rendering blood transfusions unnecessary. The patient was satisfied with the surgical results. This case indicates the feasibility of angloplasty for such cases.

Preoperative BMI and Hb levels are important predictors of massive bleeding in liver transplant patients.

This study aims to compare intraoperative bleeding during liver transplant procedures and analyze the predictive role of preoperative laboratory indicators in significant intraoperative bleeding. A retrospective analysis was conducted on 271 cases of allogeneic liver transplant patients from January 2018 to June 2023. Patients were categorized into the massive bleeding (MB) group and the non-massive bleeding (non-MB) group based on the occurrence of significant intraoperative bleeding. Preoperative laboratory parameters between the MB and non-MB groups were compared, and univariate and multivariate regression analyses were performed. ROC curves were performed to analyze the value of these parameters in distinguishing the MB and non-MB groups. In the MB group, body mass index (BMI), hemoglobin (Hb), platelet count (PLT), fibrinogen (Fib), and total protein (TP) levels were significantly lower than those in the non-MB group (p < 0.05). Conversely, prothrombin time (PT), international normalized ratio (INR), total bilirubin (TBIL), creatinine (CRE), blood urea nitrogen (BUN), the model for end-stage liver disease (MELD) score, length of stay, and hospital stay were significantly higher in the MB group compared to the non-MB group (p < 0.05). Univariate and multivariate logistic regression analyses revealed that preoperative BMI and Hb were independent risk factors for massive bleeding during liver transplantation. ROC curve analysis for predicting massive intraoperative bleeding showed that the area under the curve (AUC) of Hb was considerable (AUC: 0.83). Preoperative BMI and Hb levels are critical predictors of massive bleeding during liver transplantation, emphasizing the importance of proactive management based on these indicators for improved patient outcomes.

Development and validation of a machine learning-based early prediction model for massive intraoperative bleeding in patients with primary hepatic malignancies.

Surgical resection remains the primary treatment for hepatic malignancies, and intraoperative bleeding is associated with a significantly increased risk of death. Therefore, accurate prediction of intraoperative bleeding risk in patients with hepatic malignancies is essential to preventing bleeding in advance and providing safer and more effective treatment. To develop a predictive model for intraoperative bleeding in primary hepatic malignancy patients for improving surgical planning and outcomes. The retrospective analysis enrolled patients diagnosed with primary hepatic malignancies who underwent surgery at the Hepatobiliary Surgery Department of the Fourth Hospital of Hebei Medical University between 2010 and 2020. Logistic regression analysis was performed to identify potential risk factors for intraoperative bleeding. A prediction model was developed using Python programming language, and its accuracy was evaluated using receiver operating characteristic (ROC) curve analysis. Among 406 primary liver cancer patients, 16.0% (65/406) suffered massive intraoperative bleeding. Logistic regression analysis identified four variables as associated with intraoperative bleeding in these patients: ascites [odds ratio (OR): 22.839; P < 0.05], history of alcohol consumption (OR: 2.950; P < 0.015), TNM staging (OR: 2.441; P < 0.001), and albumin-bilirubin score (OR: 2.361; P < 0.001). These variables were used to construct the prediction model. The 406 patients were randomly assigned to a training set (70%) and a prediction set (30%). The area under the ROC curve values for the model's ability to predict intraoperative bleeding were 0.844 in the training set and 0.80 in the prediction set. The developed and validated model predicts significant intraoperative blood loss in primary hepatic malignancies using four preoperative clinical factors by considering four preoperative clinical factors: ascites, history of alcohol consumption, TNM staging, and albumin-bilirubin score. Consequently, this model holds promise for enhancing individualised surgical planning.

Total laparoscopic total gastrectomy and distal esophagectomy combined with reconstruction by transhiatal esophagojejunal Roux-en-y mediastinal anastomosis for Siewert II AEG

PurposeThe optimal procedure is still controversial about Siewert type II AEG, We are attempt to explore the efficacy and feasibility of total laparoscopic total gastrectomy and distal esophagectomy combined with reconstruction by transhiatal esophagojejunal Roux-en-y mediastinal anastomosis for Siewert type II AEG.MethodData of patients with Siewert type II AEG who received total laparoscopic total gastrectomy and distal esophagectomy combined with reconstruction by transhiatal esophagojejunal Roux-en-y mediastinal anastomosis in the Hebei General Hospital were collected from October 2020 to October 2021, The operation time, surgical blood loss, the number of dissected lymph nodes, duration of drainage tube, the length of stay in ICU, the resume oral feeding time, the length of postoperative hospital stay, postoperative complications and other related indicators of the patients were collected to evaluate the safety and feasibility of this operation.ResultA total of 17 patients received total laparoscopic total gastrectomy and distal esophagectomy combined with reconstruction by transhiatal esophagojejunal Roux-en-y mediastinal anastomosisin the treatment of Siewert type II AEG were analyzed in our research. The mean operation time was 253 ± 24.8 min (196–347 min); The median surgical blood loss was 250 ml (20–2400 ml); The average number of dissected lymph nodes were 28 ± 4.6 (17–36); The median duration of drainage tube was 5 days (3–7days); The median length of stay in ICU was 18 h(10–34 h); The median time of resume oral feeding was 6 days (5–7days); The median postoperative hospital stay was 11 days (8–15 days). Among the all enrolled patients, one patient underwent the conversion to laparotomy due to the massive intraoperative bleeding, one patient developed anastomotic stenosis at jejunum side-to-side anastomosis on the first month after surgery, there was no case of death during the operation and postoperative anastomotic fistula. All patients achieved R0 resection with an average distance of 6 cm (4–8.5 cm) from the upper margin of the tumor to the resection margin.ConclusionThe operation of total laparoscopic total gastric and distal esophagectomy combined with reconstruction by transhiatal esophagojejunal Roux-en-y mediastinal anastomosis is technically feasible and sufficiently safe in the treatment of Seiwert type II AEG from our primary clinical experience. This procedure could be one of the alternatives for the radical treatment of Siewert type II AEG.

TRANSFUSION AND INFUSION THERAPY FOR MASSIVE BLOOD LOSS. PART 1, UNEXPECTED INTRAOPERATIVE HAEMORRHAGE

TRANSFUSION AND INFUSION THERAPY FOR MASSIVE BLOOD LOSS. PART 1, UNEXPECTED INTRAOPERATIVE HAEMORRHAGE

Modern approach to transfusion therapy of massive hemorrhage due to abnormally invasive placenta

Abnormally invasive placenta (AIP), or according to modern terminology PAS (placenta accrete spectrum disorders), is one of the most dangerous obstetric pathologies of pregnancy. It is quite often accompanied by massive blood loss during childbirth. Indicators of placenta accretion are increasing sharply, taking into account the frequency of delivery by cesarean section (CS).The objective: to determine the effectiveness of the blood loss recovery program in the case of delivery of pregnant women with AIP according to modern principles of transfusion therapy of massive blood loss with the use of innovative methods of surgical hemostasis.Materials and methods. At the clinical bases of the Department of Obstetrics and Gynecology N 1 of the Shupyk National Healthcare University of Ukraine during 2018–2023, 49 pregnant women with Placenta рercreta 3a,b were operated by fundal SC.The main group included 19 pregnant women with antenatally diagnosed Placenta percreta, who were delivered by fundal SC followed by hysterectomy with fallopian tubes and restoration of blood loss according to the principles of Damage Control Resuscitation – DCR (during 2021–2023) with priority given to transfusion with blood products with minimization infusion therapy; the comparison group included 30 pregnant women with a similar diagnosis and surgical approach, who had the recovery of massive blood loss in accordance with order No. 205 of the Ministry of Health of Ukraine “Obstetric bleeding” with the priority of rapid infusion therapy with crystalloids (2018-2020).Results. All pregnant women from Pl. percreta were delivered by CS and had hysterectomy at 35–37 weeks of pregnancy with lower median laparotomy and endotracheal anesthesia. The study groups did not differ in terms of the volume of surgery, but differed in the program of transfusion therapy to restore blood loss.In the main group, in which the early start of transfusion therapy using single-group fresh-frozen plasma and erythrocyte mass was applied, a significantly lower frequency of the development of the syndrome of disseminated intravascular blood coagulation, relaparotomy, cases of severe postoperative anemia and a shorter length of stay in the obstetric hospital were determined (p&lt;0.05).Conclusions. The use of innovative surgical technologies, tranexamic acid preparations and early initiation of transfusion therapy with blood preparations with minimization of crystalloid infusion, according to the Damage Control Resuscitation strategy, in the development of massive intraoperative bleeding in cases of Placenta percreta allows to reduce the volume of blood loss and to prevent severe intra- and postoperative complication.

A comparison between stand-alone left atrial appendage occlusion and resection as a method of preventing cardiogenic thromboembolic stroke.

The present study evaluated the differences between left atrial appendage occlusion (LAAO) and left atrial appendage resection (LAAR) in terms of the safety and efficacy. From January 2018 to August 2022, 94 patients underwent a stand-alone LAAO, and 90 patients underwent stand-alone LAAR in our institution. All of these patients were included in this study. LAAO was performed via left mini-thoracotomy, and LAAR was performed via a left thoracoscopic approach. The patients' characteristics and perioperative and postoperative data were obtained by retrospectively reviewing their medical records. The mean age of the patients was 72.4 ± 10.2 (LAAO) and 66.2 ± 9.4 (LAAR) years old (P < 0.05). There were no marked differences in the mean duration of atrial fibrillation (AF) or the ratio of AF type between both groups. The average CHA2DS2-Vasc scores were 4.4 ± 1.6 (LAAO) and 2.7 ± 1.8 (LAAR) (P < 0.05), and the average HAS-BLED scores were 2.9 ± 1.0 (LAAO) and 2.2 ± 1.2 (LAAR) (P < 0.05). The mean operation time was 49 ± 20min (LAAO) and 34 ± 15min (LAAR) (P < 0.05). No substantial gaps were detected in preoperative echo-graphic findings between the groups. No significant differences were observed in the amount of intraoperative or postoperative bleeding or the rate of intraoperative massive bleeding events between the groups. Successful LAA closure was achieved in all cases in both groups. Approximately 50% of patients underwent concomitant left pulmonary vein isolation (LPVI) during surgery, indicating no significant differences between the groups (P = 0.872). The early mortality rate was 1.04% in the LAAO group and 0% in the LAAR group (P = 0.132). There was no significant difference in the rate of postoperative LAA stump thrombus between the groups (8.5% in the LAAO group and 6.7% in the LAAR group; P = 0.320). The mean follow-up period was 851 ± 500 (6-1618) days in the LAAO group and 1208 ± 357 (49-1694) days in the LAAR group. Postoperative stroke events were detected in 1 patient in each group (P = 0.432). There was no significant difference in the sinus rhythm recovery rate after LPVI between these groups (31.1% in the LAAO group and 28.6% in the LAAR group; P = 0.763). There were no significant differences between LAAO and LAAR in terms of the feasibility and the effectiveness as a method for stroke prophylaxis only to selected patients for both procedures, although further studies including the comparison between groups with the same backgrounds to confirm the authentic differences in the clinical results between these procedures.

Impact of Maternal Preoperative Hemoglobin Levels on Intraoperative Hemorrhage Risk in Placenta Accrete Spectrum Disorders: A Retrospective Cross-Sectional Study.

BACKGROUND Placenta accreta spectrum (PAS) disorders involve abnormal adhesion or invasion of chorionic villi through the myometrium and uterine serosa. Maternal anemia during pregnancy is common and may contribute to complications during delivery, particularly with abnormal placentation. This study examines the association between preoperative maternal hemoglobin levels and the risk of intraoperative massive hemorrhage in pregnant women with PAS disorders. MATERIAL AND METHODS A retrospective study included 538 consecutive participants (mean age=31.12&plusmn;4.68 years) who underwent cesarean sections and met the diagnostic criteria for PAS disorders. Logistic regression analysis was performed to investigate the relationship between maternal preoperative hemoglobin levels and the risk of massive intraoperative hemorrhage (blood loss ≥1500 mL). RESULTS The incidence of intraoperative massive hemorrhage among patients with PAS disorders was 38.66%. The mean preoperative maternal hemoglobin level was 10.99&plusmn;1.39 g/dL, and overall anemia incidence (<11 g/dL) was 48.88% in our study. After adjusting for potential confounders, a non-linear relationship was observed between preoperative maternal hemoglobin levels and the risk of intraoperative massive hemorrhage. When the preoperative hemoglobin level of pregnant women was below 11.5 g/dL (OR=0.52, 95% CI 0.39-0.70), the lower hemoglobin level significantly increased the risk of intraoperative hemorrhage. CONCLUSIONS Maternal preoperative hemoglobin levels were inversely associated with the risk of massive intraoperative hemorrhage in PAS disorders. A non-linear relationship was identified, with a turning point at 11.5 g/dL. These findings emphasize the importance of monitoring and managing maternal hemoglobin levels to mitigate the risk of intraoperative hemorrhage in pregnant women with PAS disorders.

Head Trauma Associated with Supra- and Infratentorial Epidural Hematoma: Diagnostic and Surgical Considerations

Supra- and infratentorial epidural hematoma (SIEDH) is a rare type of intracranial epidural hematoma. Due to the potential of vigorous hemorrhage from the injured transverse sinus (TS), it poses a challenge for neurosurgeons to evacuate the SIEDH. The medical records and radiographic studies were retrospectively reviewed to investigate the clinical and radiographic characteristics, clinical course, surgical findings and outcome in 34 patients with head trauma associated with SIEDH. Patients treated surgically had a lower Glasgow Coma Scale score than those treated conservatively (P= 0.005). The surgical group had statistically larger thickness and volume of the SIEDH than those in the conservative group (P < 0.0001 and P < 0.0001, respectively). Six patients experienced significant intraoperative blood loss, and copious bleeding from the injured TS was noted in 5 (83.3%) of these patients. Five (50%) of 10 patients undergoing simple craniotomy experienced significant blood loss. However, only 1 patient (11.1%) undergoing strip craniotomy experienced significant blood loss, but no intraoperative shock. All patients experiencing massive blood loss and intraoperative shock underwent simple craniotomy. There was no statistical difference in the outcome between the conservative and surgical groups. When operating on SIEDH, the possibility of vigorous bleeding from the injured TS and intraoperative massive bleeding should be kept in mind. Strip craniotomy that allows hitching the stripped dura to the bone strip overlying the TS may be a better method for the evacuation of SIEDH.

The Implications of Multiple Repeat Cesarean Deliveries On Maternal Morbidity

OBJECTIVE: This study aimed to assess the obstetric outcomes of cesarean delivery (CD) in a cohort of pregnant women who had a history of four or more previous CDs and compared them with those who had a history of three or fewer previous CDs. STUDY DESIGN: The cohort of this retrospective study consisted of all pregnant women who gave birth in our hospital via elective or emergency CD and who had previously undergone one or more other cesarean sections. Pregnant women who had a history of four or more CDs were included in the multiple repeat CD group, and cases who had a history of fewer than 4 CDs were enrolled in the lower-order repeat CD (comparison) group. Demographic data, medical history, clinical features, intraoperative events, and postoperative complications were recorded. RESULTS: The multiple repeat CD group comprised 63 women, and the lower-order repeat CD group (comparison group) included 1097 cases. Intraabdominal dense adhesions (28.6% versus 14.1%, p=0.002), placenta previa (11.1% versus 4.1%, p=0.009), placenta accreta spectrum (PAS) (7.9% versus 2.4%, p=0.008), bladder injury (6.3% versus 1.7%, p=0.011), intraoperative massive hemorrhage (7.9% versus 2.2%, p=0.004), uterine artery ligation (4.8% versus 1.1%, p=0.012), internal iliac artery ligation (4.8% versus 1.2%, p=0.008), cesarean hysterectomy (4.8% versus 1.5%, p=0.045), blood transfusion (12.7% versus 4.1%, p=0.001), and maternal intensive care unit (ICU) admission (14.3% versus 2.0%, p&lt;0.001) were significantly more common among women in the multiple-repeat CD group compared with the lower-order repeat CD group. CONCLUSIONS: Pregnant women having multiple repeat CDs have a significantly increased risk of dense adhesions, placenta previa, PAS, intraoperative massive hemorrhage, blood transfusion, bladder injury, additional surgical interventions, including uterine artery ligation, internal iliac artery ligation, cesarean hysterectomy, and maternal ICU admission.

Successful Anesthesia Management of Complicated Case of Placenta Previa Accreta with Massive Intraoperative Bleeding and Incidentally Detected COVID-19

Placenta previa accreta is a serious obstetric condition with high risk of postoperative complications requiring the use of multiple health resource. The risk is higher in patients with previous history of caesarean section. Moreover, presence of COVID-19 infection can deteriorate the disease process. In this case report it was reported that the case of successful anesthetic management of a complicated placenta previa accreta with massive intraoperative bleeding with incidental COVID-19 diagnosis.

Placental Area in the Lower Uterine Segment, Cervical Length, and Clinical Outcome in Pregnancies With Complete Placenta Previa.

Complete placenta previa is associated with a higher percentage of adverse clinical outcomes and magnetic resonance imaging (MRI) is widely used in the preoperative examination of patients with placenta previa. To evaluate the effectiveness of the placental area in the lower uterine segment and cervical length in identifying the adverse maternal-fetal outcomes in women with complete placenta previa. Retrospective. A total of 141 pregnant women (median age, 32; age range, 24-40 years) with complete placenta previa were examined by MRI to evaluate the uteroplacental condition. A 3 T with T1 -weighted imaging (T1 WI), T2 -weighted imaging (T2 WI), and half-Fourier acquisition single-shot turbo spin echo (HASTE) sequence. The association of the placental area in the lower uterine segment and cervical length measured using MRI with the risk of massive intraoperative hemorrhage (MIH) and maternal-fetal perinatal outcomes were determined. The adverse neonatal outcomes (preterm delivery, respiratory distress syndrome [RDS], admission to neonatal intensive care unit [NICU]) were analyzed in different groups. The t-test, Mann-Whitney U test, Chi-square, Fisher's exact test, and receiver operating characteristic (ROC) curve were used, and a P < 0.05 indicated a statistically significant difference. The mean operation time, intraoperative blood loss, and intraoperative blood transfusing were significantly higher in patients with large placental area and short cervix than in patients with the small placental area and long cervix, respectively. The incidence of adverse neonatal outcomes was significantly higher in the large placenta area group and short cervix group than in the small placenta group area and long cervix group, respectively, such as preterm delivery, RDS, and NICU. By combining placental area with cervical length sensitivity and specificity increased to 93% and 92%, respectively, for the identification of MIH > 2000 mL with area under the receiver operating curve (AUC) 0.941. Large placental area and short cervical length may be associated with a high risk of MIH and adverse maternal-fetal perinatal outcomes in patients with complete placenta previa. 2.

Uneventful Cochlear Implantation through Round Window Approach in a Child with Persistent Stapedial Artery: A Case Report

Persistent stapedial artery (PSA) is a rare congenital vascular anomaly, with both clinical and surgical implications. When encountered during middle ear surgery, it represents a challenge to the otologic surgeon, since damage to this artery could lead to massive intraoperative bleeding and poor surgical exposure. Here we report the case of a 3-year-old boy with prelingual and profound bilateral sensorineural hearing loss who was referred to our Otolaryngology-Head and Neck Surgery Department for cochlear implant evaluation. Pre-operative computed tomography (CT) examination of the temporal bone confirmed the diagnosis of PSA. Further evaluation showed no contraindication for surgery and the patient underwent cochlear implantation using the classic transmastoid, facial recess approach. During surgery the vessel was coursing far enough from the round window niche, making it possible to achieve safe and complete electrode insertion into the scala tympani of the cochlear basal turn. This case demonstrates that cochlear implantation is safe and feasible in patients with PSA. Thorough analysis of the preoperative temporal bone CT scan might help with surgical planning by identifying this anomaly prior to surgery.

Bilateral Carotid Paraganglioma: Case Report; Successful Surgical Excision, Radiological Image and Review of the Literature

Introduction: Carotid body tumors are rare neoplasms that generally present as asymptomatic slow-growing masses in the neck, commonly called cervical paragangliomas, highly vascularized whose cells originate from the embryonic neural crest, carotid glomus tumor is uncommon, representing 1 out of every 30,000 head and neck tumors, they are located in the adventitia of the vessels, they usually grow surrounding the arteries of the carotid bifurcation and the nerves that surround it, in Ecuador the prevalence is at 55 years of age with greater frequency in women [1]. Clinical Case: A 33-year-old female patient with no significant clinical history, presented with a painful hard mass in the right cervical region that progressively increased in size, for the past 6 months. On physical examination, a tumor in the right cervical region of approximately 5 centimeters in diameter was found, with a hard consistency attached to deep planes, for which Eco Doppler and AngioTac of the neck were performed, which reported bilateral carotid paraganglioma. Excision of the glomus was necessary due to its size right carotid artery, surgery using a right cervico-lateral approach, identifying the vascular tumor mass of 4.8 x 2.9 x 2.8 cm in diameter, which was located in the carotid bifurcation. Removal of Shamblin II right carotid body paraganglioma by temporary clamping of the common carotid artery and the digital dissection method, there was no intraoperative massive bleeding or cranial nerve deficits in the postoperative period with favorable evolution, surgical wound in good condition during follow-up in outpatient consultation. Conclusion: Glomus carotid tumors are generally benign and diagnosed late. Imaging studies are essential for its diagnosis and staging.

Analysis of the Risk Factors for Massive Hemorrhage in Pernicious Placenta Previa and Evaluation of the Efficacy of Internal Iliac Artery Balloon Occlusion.

To investigate the risk factors of intraoperative massive hemorrhage in patients with pernicious placenta previa (PPP) and analyze the value of bilateral internal iliac artery balloon occlusion in Cesarean section for these patients. The clinical data of 134 patients with PPP admitted to the Second Hospital of Shanxi Medical University from January 2012 to January 2019 were analyzed. A logistic regression analysis was used to analyze the risk factors for intraoperative massive hemorrhage in PPP. The study subjects were divided into the intervention group (38 cases) and the routine group (96 cases) according to whether bilateral internal iliac artery balloon occlusion was conducted during the operation. The differences in some clinical indicators were compared between the two groups. The risk factors for intraoperative massive hemorrhage in PPP were age ≥35 years, gestational age ≥34 weeks, complete placenta previa, and the presence of placenta accreta. The differences in the operation time, postoperative transfer to the intensive care unit, postoperative length of the hospital stay, and neonatal weight and score were not statistically significant between the intervention group and the routine group (P > 0.05 for all). While the intraoperative blood loss and the transfusion volume in the intervention group were lower than in the routine group, the hospitalization cost was higher in the former than in the latter, and the differences were statistically significant (P < 0.05 for all). Moreover, there was no case of hysterectomy in the intervention group, while there were two cases of hysterectomies in the routine group. The risk factors for intraoperative massive hemorrhage in PPP were age ≥35 years, gestational age ≥34 weeks, complete placenta previa, and the presence of placenta accreta. Internal iliac artery balloon occlusion during PPP could reduce intraoperative blood loss and the hysterectomy rate.
