A case of gastrointestinal perforation following transarterial embolization for an intramural hematoma after cold snare polypectomy of an adenoma in the transverse colon.

We encountered a case of a large hematoma developing with perforation shortly after a cold snare polypectomy for a colorectal adenoma. The patient underwent cold snare polypectomy for a 3-mm type Is lesion in the transverse colon at another facility. Two hours later, she visited the emergency room due to abdominal pain. Contrast-enhanced computed tomography revealed a 70 mm, high-intensity mass in the transverse colon with contrast extravasation. We attempted transcatheter arterial embolization to stop the bleeding. Several hours later, the anemia had not worsened, but the severe abdominal pain persisted. Urgent laparoscopic right hemicolectomy was performed due to the possibility of gastrointestinal perforation. The surgery was successfully completed. Pathology reports confirmed the presence of an intramural hematoma in the proximal transverse colon with hemorrhagic infiltration of all layers, along with extensive ischemic changes. A perforation was identified in this area, with mucosal defects observed near the hole, possibly due to cold snare polypectomy.

Spontaneous neck hematoma in a hemodialysis patient: A case report.

We present a 60-year-old maintenance hemodialysis patient who initially presented with neck swelling, which was diagnosed as a thyroid issue. Following a hemodialysis session, the swelling in the neck progressively enlarged, leading to respiratory distress and eventual cardiac arrest. During a life-saving tracheotomy, dark red blood was observed, and endotracheal intubation was urgently performed. Subsequent computed tomography examination identified multiple areas of slight high-density images in the nasopharyngeal cavity, oropharyngeal cavity, and esophagus. As time passed, the patient's hematoma underwent spontaneous absorption, but signs of recovery were absent. We discuss the rarity, etiology, diagnosis, and management of spontaneous neck hematoma in maintenance hemodialysis patients.

Left Ventricular Intramyocardial Dissecting Hematoma With Late Ventricular Tachycardia Storm.

This case describes an uncommon discovery of a left ventricular intramyocardial dissecting hematoma in a patient experiencing a ventricular tachycardia storm. Imaging modalities, including 2-dimensional and 3-dimensional echocardiography and cardiac magnetic resonance, assisted in diagnosing the intramyocardial dissecting hematoma. The patient underwent conservative treatment and received a single-chamber implantable cardioverter defibrillator.

Spontaneous Auricular Hematoma - An Unusual Complication of Dengue fever.

Dengue is humans' most prevalent and crucial arthropod-borne viral illness. The majority of dengue fever patients have no symptoms, but certain individuals may progress to dengue shock syndrome or dengue hemorrhagic fever. Spontaneous auricular hematoma is a rare complication of dengue fever. We report a unique case of spontaneous pinna hematoma in a young, healthy patient who presented with an unprovoked pinna swelling while being treated for dengue fever. The patient underwent aspiration, drainage, and compression dressing over the auricular hematoma with antibiotic coverage and was discharged well. Early identification of this potential warning symptom may avoid permanent ear deformity.

Predicting Intracerebral Hemorrhage Expansion with Inflammation Indices, Non-Contrast Computed Tomography Signs and Computed Tomography Angiography Spot Sign.

Aim: We aimed to investigate whether a combination of inflammatory and radiological biomarkers can improve intracerebral hemorrhage (ICH) hematoma expansion (HE) prediction. Methods: A retrospective analysis was conducted on patients with primary supratentorial ICH within 6 h of symptom onset between September 2021 and April 2022. Predictors were explored using univariate and logistic regression analysis. We compared the discrimination of inflammatory indice-based model 1 with models 2 and 3, which included image biomarkers, using the receiver operating characteristic curve and De Long test for area under the curve comparison. Results: A total of 205 eligible participants were included, 56 (27.3%) of whom experienced HE. The neutrophil-to-lymphocyte ratio (NLR), black hole sign, BAT score, and computed tomography angiography (CTA) spot sign were independently associated with HE in the logistic regression (P<0.05). The addition of non-contrast computed tomography (NCCT) signs did not provide significant discrimination improvement (AUC, Model 2 0.875 [95% CI, 0.822-0.929] versus Model 1. 0.811 [95% CI, 0.747-0.875], p=0.089), whereas the added value of the CTA spot sign remained statistically significant (AUC, Model 3 0.922 [95% CI, 0.878-0.966] versus Model 2; p=0.030; Model 3 versus Model 1, p=0.005). Conclusion: The combination of inflammatory and radiological biomarkers can predict HE with a satisfactory performance.

A case of spontaneous bilateral epidural hematoma associated with decreased coagulation factor XII activity: case report and literature review.

Epidural hematoma typically manifests following craniocerebral trauma, stemming from injury to the meningeal artery or venous system, predominantly on one side. Instances of spontaneous epidural hematoma are uncommon, with occurrences of spontaneous bilateral epidural hematoma being exceedingly rare. Sickle cell disease, adjacent paranasal sinusitis, and tumor metastases are the most prevalent causes of spontaneous epidural hematoma. This case study presents an individual with abdominal liposarcoma exhibiting reduced coagulation factor XII activity, who experienced sudden unconsciousness due to spontaneous acute bilateral epidural hematoma, and subsequently achieved a favorable outcome following surgical intervention.

Consensus statement by the Belgian Society of Neurosurgery and literature review on the diagnosis and management of postoperative spinal epidural hematoma.

Introduction: Postoperative spinal epidural hematoma (SEH) is a potentially devastating complication for patients and caregivers, and a leading cause for litigation in spine surgery. This article provides a literature review and the consensus statement of the Belgian Society of Neurosurgery (BSN) on the management of postoperative SEH. Research question: Can we implement current evidence to establish a framework on the management of postoperative SEH? Material and methods: Based on a Pubmed search, abstracts were screened for topics covering incidence, pathophysiology, risk factors, surveillance, diagnosis, treatment, and outcome. Relevant topics are presented in a narrative review format, followed by a consensus statement of the BSN with emphasis on rapid diagnosis and treatment. Results: Symptomatic SEH is rare (0.3-1%) and can have an insidious onset with rapid progression to neurological deficits. Recurring risk factors are coagulation deficiencies and multilevel surgery. The protective effect of a postoperative drainage system is uncertain, and early thrombo-embolic prophylaxis does not increase the risk of SEH. Prognosis is dependent on residual neurological function and critically, on the time to reintervention. There is a need for structured neurological observation formats after spine surgery. Discussion and conclusion: Symptomatic SEH after surgery is an unpredictable and severe complication requiring rapid action to maximize outcomes. The BSN proposes three nuclear terms central to SEH management, converging on a triple 'S': 1) high level of suspicion 2) speed of diagnosis and 3) immediate surgery. All spine centers can benefit from an institutional protocol in which SEH should be treated as an emergency.

A penetrating aortic ulcer rapidly evolving into aortic dissection in a patient presenting with respiratory tract infection to the emergency department: an acute aortic syndrome case report.

BACKGROUND: Penetrating aortic ulcers (PAU) are life-threatening conditions which derive from severely advanced atherosclerotic lesions of the aorta. The clinical course is unpredictable; thus clinical vigilance should be maintained. It is very challenging to separate PAU from co-existing AAS as predisposing factors and findings overlap. CASE PRESENTATION: Case of 58-year-old gentleman, who presented for atypical chest pain in the setting of respiratory tract infection. Computed Tomographic angiography (CTA) of the chest showed a large PAU and intramural hematoma which rapidly progressed into an acute aortic dissection in the emergency department. Close follow up with cardiac point of care ultrasound one hour later detected an intimal flap which was not initially present on CTA. Patient underwent surgical aortic graft replacement and had an uneventful in-hospital stay. DISCUSSION: This case underlines the importance of broadening differential diagnoses in atypical presentations in patients with risk factors. Prompt intervention and careful management are imperative to optimize patient outcomes and prevent complications of aortic lesions. Cardiac point of care ultrasound can help in detecting progression of dynamic atherosclerotic diseases such as acute aortic syndrome.

Unmasking Nasal Septal Hematoma/Abscess: A Systematic Review and Meta-analysis.

Objective: We aim to discuss the demographics, symptoms, bacteriology, treatment, and sequelae associated with nasal septal hematoma/nasal septal abscess (NSH/NSA). Data Sources: CINAHL, PubMed, and Scopus were searched from inception until October 15, 2023. Review Methods: Preferred Reporting Items for Systematic Reviews and Meta-analysis 2020 guidelines were followed. Inclusion criteria included patients who were diagnosed with a traumatic NSH/NSA. NSH/NSA due to surgical procedures was excluded. Demographics included N of patients, patient age, and gender. Symptoms, antibiotics given, bacteriology, and sequelae were analyzed. Meta-analysis of continuous measures (mean, median), and proportions (%) with a 95% confidence interval (CI) was conducted. Results: Thirty studies (N = 598) were included. In total, 72.1% were males (95% CI: 67-78). The total mean age was 21.6 years (range: 0.2-85, 95% CI: 17.2-26.1). The mean time from trauma to diagnosis was 8.2 days. Common symptoms at presentation included nasal obstruction/congestion at 60.3% (95% CI: 37.1-81.4), nasal pain at 30.0% (17.2-44.6), swelling at 20.4% (8.7-35.5), headache at 15.5% (7.3-26.0), and fever at 13.9% (7.3-22.2). The most common pathogens isolated included Staphylococcus aureus at 56.5% (49.0-63.8), Streptococcus species at 8.9% (5.2-14.0), and Klebsiella pneumoniae at 6.3% (3.2-10.8). Antibiotics given included amoxicillin-clavulanate at 10.3% (4.5-18.2), metronidazole at 9.5% (1.1-24.9), ampicillin-sulbactam at 8.9% (0.4-26.5), and unspecified antibiotics at 39.7% (13.8-69.2). The most common sequelae were nasal septal deformity/cartilage destruction at 14.3% (7.7-22.6). Conclusion: NSA/NSH has an 8-day delay in diagnosis from the time of trauma. First-line practitioners should be made aware of the signs and symptoms of this condition to minimize the risk of morbidity.

Unmasking hidden risks: cerebral venous sinus thrombosis and spontaneous subdural hematoma in women on oral contraceptives - insights from a case report and systematic literature review.

BACKGROUND AND OBJECTIVE: Cerebral venous thrombosis (CVT) is a rare but critical condition, particularly in young women, often linked to oral contraceptive use. It can lead to complications like subdural hematoma (SH), which are challenging to diagnose and manage. We report the case of a 39-year-old woman who presented with severe headaches and neurological symptoms, leading to a diagnosis of chronic SH and CVT, associated with long-term oral contraceptive use. This case is unique as it documents the first known instance of chronic SH associated with CVT induced by oral contraceptives. Our objective was to explore this association using the Bradford Hill criteria and to review the diagnostic and therapeutic challenges of CVT and SH in this population. METHODS: We conducted a systematic literature review adhering to PRISMA guidelines, focusing on SH cases linked to CVT in women using oral contraceptives. RESULTS: Including our case, four cases of SH associated with CVT secondary to oral contraceptive use were identified. Common symptoms included severe headache and neurological deficits. All patients received anticoagulation therapy, with surgical intervention required in severe cases. Prognosis was generally favorable with appropriate management. CONCLUSION: This case emphasizes the importance of considering CVT in women presenting with spontaneous SH, particularly those on oral contraceptives. Early diagnosis, careful clinical and radiological monitoring, and timely surgical intervention are crucial for optimal outcomes.

Efficacy of neuroendoscopy-assisted surgery in the treatment of chronic subdural hematoma: a meta-analysis.

BACKGROUND: Chronic subdural hematoma (CSDH) is one of the most common diseases in neurosurgery. It is the result of chronic intracranial hemorrhage that converges between the dura mater and arachnoid three weeks after externally injuring the head. Chronic subdural hematomas are a common complication in neurosurgery. With the gradual increase in the amount of hematoma, the surrounding brain tissue is pushed and compressed, resulting in corresponding clinical symptoms and signs. It is reported that the overall incidence rate of CSDH is 1.72 to 20.6 per 100,000 people every year, and the incidence rate of the elderly is particularly high. METHODS: The computer retrieves eight databases to obtain controlled trials at home and abroad on the effects of neuroendoscopy-assisted surgery in patients with chronic subdural hematoma. After a rigorous literature quality evaluation, data analysis was performed using RevMan 5.3 software. RESULTS: Twenty studies were ultimately included in this meta-analysis. Seventeen studies reported the Recurrence rate of the test group and the control group, which was significantly lower (OR 0.27; 95% Cl 0.18, 0.38; P < 0.01) than the control group, Recovery rate (OR 1.18; 95% Cl 1.01, 1.38; P = 0.03), Total effective rate (OR 1.11; 95% Cl 1.04, 1.17; P < 0.01), Operative time (SMD 15.78; 95% Cl 9.69, 21.86; P < 0.01), Hospital stay (SMD - 1.66; 95% Cl - 2.17, - 1.14; P < 0.01) and Complications (OR 0.48; 95% Cl 0.30, 0.78; P < 0.01). CONCLUSION: The results of this study suggest that neuroendoscopy-assisted surgery may be effective in patients with chronic subdural hematoma, as evidenced by recurrence rate, recovery rate, total effective rate, operative time, hospital stay, complications, and the above conclusions need to be verified by more high-quality studies.

Middle meningeal artery embolization for organized chronic subdural hematoma combined with minimal evacuation surgery: Two case reports.

Organized chronic subdural hematoma (OCSDH) is a rare condition lacking standardized treatment protocols. Middle meningeal artery (MMA) embolization has recently demonstrated promising outcomes in managing chronic subdural hematoma (CSDH). We present 2 cases of OCSDH treated with endovascular embolization and minimal evacuation surgery. The first case involved an 83-year-old male with a history of left CSDH drainage, admitted urgently due to right hemiplegia and dysarthria. CT scans confirmed recurrent CSDH. A small craniotomy was performed to decompress the thick hematoma, followed by drain placement. Postoperative magnetic resonance imaging (MRI) indicated OCSDH. Seven days later, MMA embolization with 25% n-butyl-2-cyanoacrylate (NBCA) was performed under local anesthesia. The patient's symptoms improved, and the hematoma resolved within 6 months without recurrence. The second case involved a 76-year-old male with right CSDH and thrombocytopenia (platelet count of 19,000/µL), diagnosed with immune thrombocytopenia. MRI indicated OCSDH. Due to the risk associated with craniotomy, a burr hole perforation and MMA embolization were planned, accompanied by a platelet transfusion. Left MMA embolization with 20% NBCA was performed, followed by burr hole enlargement for decompression and drain placement. The patient's symptoms improved postoperatively, and his platelet count stabilized with steroid therapy and thrombopoietin. The hematoma resolved within 3 months without recurrence. These cases indicate that MMA embolization combined with small craniotomy or perforation may be an effective treatment strategy for OCSDH.

Intracranial epidural hematoma after spinal anesthesia for cesarean section: a case report.

BACKGROUND: Although subdural hematoma is a rare complication after spinal anesthesia, there have been no reports of an intracranial epidural hematoma after cesarean section with spinal anesthesia. CASE PRESENTATION: A 32-year-old nulliparous woman at the 35th week of a twin pregnancy underwent an emergency cesarean section due to her first contraction. She had no preoperative complications and the spinal anesthesia was uneventful, with 0.5% bupivacaine 12 mg and fentanyl 15 µg from the L3/4 intervertebral space. She complained of headache and nausea 15 min after spinal anesthesia, demonstrating a consciousness disturbance after surgery. Computed tomography 2 h after the cesarean section revealed an intracranial epidural hematoma. She underwent decompressive craniotomy 1 h later. CONCLUSION: This case highlights the possible development of an intracranial epidural hematoma in low-risk obstetric patients.

Distribution of the middle meningeal artery variants in patients undergoing embolization for chronic subdural hematoma.

INTRODUCTION: The middle meningeal artery (MMA) is a major dural vessel that plays a significant role in developing chronic subdural hematomas (cSDH). Understanding its variable anatomy is essential for the effective management of cSDH and the prevention of complications. METHODS: Middle meningeal artery anatomy was retrospectively assessed in a population of 92 patients who underwent digital subtraction angiography of cerebral vessels before middle meningeal artery embolization for chronic subdural hematoma. RESULTS: We assessed 121 middle meningeal arteries in 92 patients who underwent digital subtraction angiography for chronic subdural hematoma treatment from October 2020 to July 2023. The most common type in the extended Adachi classification was IC (19.82%) and the rarest was IB (6.31%). The anterior branch of the MMA was the most frequently dominant, while the most common origin of the posterior branch was observed in the distal segment. We reported 4 cases (3.31%) of the MMA arising from the ophthalmic artery. CONCLUSIONS: The most common configuration of MMA was Adachi-type IC. The MMA most often originated from the maxillary artery. The anterior branch of the MMA was typically dominant, and the posterior branch most frequently originated from the distal segment. There was no significant impact of Adachi type on treatment results or fluoroscopy time.

Comparison of Postoperative Epidural Hematoma Formation Between Biportal Endoscopic Spine Surgery and Conventional Microscopic Surgery: A Randomized Controlled Trial.

BACKGROUND: Biportal endoscopic spine surgery (BESS) has become widely recognized as a minimally invasive method for spinal decompression and discectomy. However, postoperative epidural hematoma (POEH) presents a significant risk in spinal surgery due to its potential to compress neural elements and lead to neurological deficits. This study compares the clinical and radiological outcomes of BESS with those of conventional microscopic surgery. METHODS: In this single-center, single-blinded, actively controlled randomized clinical trial, 46 patients undergoing single-level posterior decompression or discectomy for spinal stenosis or herniated intervertebral discs were enrolled. Participants were randomly allocated to either the conventional microscopic surgery group or the BESS group. Experienced spine surgeons performed all procedures. Postoperative magnetic resonance imaging assessments were conducted following the removal of the drain system. Outcome measures included the cross-sectional area (CSA) of the dura sac and POEH, as well as the incidence of neurological deficits. RESULTS: The demographic and baseline characteristics of the patients were similar across the 2 groups, with 24 in the conventional group and 22 in the BESS group. There were no significant differences in the preoperative and postoperative CSA of the dura sac between the groups. However, the BESS group exhibited a significantly larger CSA of POEH (0.36 ± 0.34 cm²) compared with the conventional group (0.17 ± 0.15 cm², P = 0.033). Despite this higher incidence of POEH, there was no corresponding increase in neurological deficits or revision surgeries. CONCLUSION: The findings indicate that while BESS achieves decompression comparable to that of conventional microscopic surgery, it is associated with a higher incidence of epidural hematomas. Importantly, these hematomas did not result in an increased rate of neurological deterioration or the need for surgical interventions. Further studies with larger sample sizes and extended follow-up are required to confirm these results and further refine the BESS technique. CLINICAL RELEVANCE: Despite a higher incidence of epidural hematomas, BESS offers comparable decompression to microscopic surgery without increased neurological risks, making it a viable, less invasive option for patient care.

Practice variations, trends, and outcomes of drain use in thyroidectomy: A NSQIP study.

BACKGROUND: The benefit of drains remains unclear and variable among thyroid surgeons. This study examines the utility and trend in drain use after thyroidectomy. METHOD: This is a retrospective cross-sectional study utilizing a pooled sample of thyroidectomy patients from the 2016-2019 NSQIP. The impact of drain use on outcomes of interest (rate of postoperative neck hematoma (PNH)-primary outcome, and length-of-stay (LOS)-secondary outcome), as well as year-over-year and practice variations were evaluated using inverse-probability-weighted-regression adjustment and multivariable logistic regression analyses. RESULTS: Of 24,370 patients, 6673(27.4 â€‹%) received drains. The average LOS and PNH rates were 27.3 â€‹h and 1.87 %, respectively. Drain use increased year-over-year for concomitant neck dissections (OR â€‹= â€‹1.08,p â€‹= â€‹0.002). Year-over-year odds of drain use trended down across specialties (OR â€‹= â€‹0.96,p â€‹= â€‹0.005); however, ENT used drains more frequently than General Surgeons (RR â€‹= â€‹3.06, 95%CI â€‹= â€‹2.91-3.22). Drains were associated with longer LOS (mean-difference â€‹= â€‹9.6hrs, 95%CI 8.51-10.62) with no effect on PNH rates (RR â€‹= â€‹0.96,p â€‹< â€‹0.05). CONCLUSION: Drain use is decreasing, but practice variations across specialties persist. Post-thyroidectomy drain use was associated with longer LOS with no effect on PNHR.

Mediastinal and thoracic hematoma following transradial cerebral angiography: a case report.

BACKGROUND: Cerebral angiography through the transradial approach (TRA) is associated with a low risk of complications, but in rare cases, these complications can be life-threatening. CASE PRESENTATION: A 56-year-old female patient was admitted for transradial cerebral angiography due to the complaint of right limb weakness and the diagnosis of cerebral infarction and cerebral artery stenosis. During the procedure, the patient coughed with expectoration and complained of throat discomfort, palpitations, and pains in the right shoulder and back. Emergency CT scan indicated hematoma in the middle mediastinum and the right thoracic cavity, and perforation of a branch of the subclavian artery was highly suspected. Subclavian artery angiography was conducted immediately, which revealed a patchy contrast medium overflow in a branch of the right costocervical trunk. Selective endovascular occlusion therapy was performed successfully with gelfoam particles and placement of 2 microcoils. At 12 days after cerebral angiography, the patient recovered well and was discharged from the hospital. CONCLUSION: Mediastinal and thoracic hematoma may occur due to vessel perforation during TRA cerebral angiography, in which guidewire advancement must be cautious. Early detection and appropriate countermeasures can reduce the severity of vascular perforation and subsequent hematoma.

Idiopathic Spinal Epidural Hematoma: A Near Miss of a Rare Entity.

Spinal epidural hematomas (SEH) are rare, and cases with a spontaneous etiology are even more infrequent. Management of spontaneous SEH varies, with surgical or conservative approaches determined by the severity of deficits and symptom resolution. Adverse prognostic factors may include thoracic segment location, anticoagulation use, severe neurologic deficits at admission, sphincter dysfunction, and rapid progression. We report a patient with a sudden onset of bilateral lower limb weakness and reduced urinary output. Magnetic resonance imaging was conducted and indicated an epidural hematoma extending from T11 to L4. Surgical decompression and hematoma extraction were performed successfully resulting in the complete resolution of symptoms. This case underscores the importance of considering spontaneous SEH in patients lacking conventional risk factors, such as a history of trauma, when presenting with symptoms of bilateral lower limb weakness and decreased urine output. Depending on the severity of symptoms and the occurrence of spontaneous and rapid improvement, the patient may benefit from surgical intervention, which ameliorated the patient's symptoms in this case.
