Comparison of burr hole drainage and craniotomy for acute liquid epidural hematoma in pediatric patients.

PURPOSE: To compare the impact of burr hole drainage and craniotomy for acute liquid epidural hematoma (LEDH) in pediatric patients. METHODS: This retrospective study enrolled pediatric patients with LEDH who underwent surgery in the Affiliated Hospital of Nanyang Medical College, China, between October 2011 and December 2019. According to the surgical procedure, patients were divided into the craniotomy group and the burr hole drainage group. RESULTS: A total of 21 pediatric patients were enrolled (14 males, aged 7.19 ± 2.77 years), including 13 cases in the burr hole drainage group and 8 patients in the craniotomy group. The operation time and hospitalization period in the burr hole drainage group were 33.38 ± 6.99 min and 9.85 ± 1.07 days, respectively, which were significantly shorter than that in the craniotomy group (74.25 ± 9.68 min and 13.38 ± 1.71 days, respectively; all p < 0.05). The Glasgow Coma Scale (GCS) score after burr hole drainage was significantly improved than before (median: 15 vs 13, p < 0.05). No serious complications were observed in either group; one patient in the craniotomy group developed an infection at the incision point. All patients were conscious (GCS score was 15) at discharge. CONCLUSION: Compared with craniotomy, burr hole drainage was associated with better clinical outcomes and early recovery in patients with LEDH.

Conservative Treatment for Spontaneous Resolution of Postoperative Symptomatic Thoracic Spinal Epidural Hematoma-A Case Report.

Introduction: Postoperative epidural hematomas of the cervical and thoracic spine can pose a great risk of rapid neurological impairment and sometimes require immediate decompressive surgery. Case Report: We present the case of a young patient operated on for stabilization of a two-level thoracic vertebra fracture who developed total paralysis due to an epidural hematoma postoperatively. The course of epidural hematoma was quickly reversed with the help of a conservative technique that prevented revision surgery. The patient regained complete neurologic function very rapidly, and has been well on every follow-up to date. Conclusion: There is a role of similar maneuvers as described in this case to be employed in the management of postoperative epidural hematomas. However, prolonged watchful waiting should still be discouraged, and patients should remain ready for revision surgery if there are no early signs of rapid recovery.

Delayed Diagnosis of Cervical Epidural Hematoma in a 3-Year-Old Boy: A Case Report.

CASE: A 3-year-old boy presented to the emergency department with torticollis after a fall. With normal cervical radiographs and neurologic exam, he was diagnosed with cervical strain and discharged. After 2-week progressive symptoms, he was referred to a pediatric spine surgeon. Magnetic resonance imaging (MRI) revealed a cervical epidural hematoma, which was then surgically evacuated. He recovered fully and remains symptom-free 2 years later. CONCLUSION: Pediatric spinal epidural hematoma is a rare condition with potentially serious outcomes yet often nonspecific symptoms. Timely management based on a comprehensive evaluation of symptoms and imaging findings is crucial in improving patient outcomes.

Spontaneous Cervical Epidural Hematoma Presenting with Respiratory Failure: A Case Report and Literature Review.

CASE: A 62-year-old woman who had an unremarkable medical history presented with sudden headache and neck pain. After the presentation, complete quadriplegia and respiratory arrest developed, and the patient was urgently intubated. Magnetic resonance imaging revealed an extensive epidural hematoma (EH), and emergency hematoma evacuation was performed. At the 1-year follow-up visit, the patient had no motor deficits. CONCLUSION: We reported a case of spontaneous cervical EH presenting with respiratory failure that was successfully treated with surgical management. Literature review has shown that the surgical outcome is very poor; nevertheless, prompt surgical decompression of the spinal cord can minimize neurological sequelae.

First report of lumbar spinal epidural hematoma after pelvic ring fracture.

INTRODUCTION: Spinal epidural hematoma is a rare condition that most commonly occurs as a complication of spinal surgery. For patients with neurological deficits, surgical decompression can generally provide good outcome. CASE: A 56-year-old, otherwise healthy, patient was admitted to the orthopedic emergency department with a pelvic ring fracture. Over the course of 4 days, a lumbar spinal epidural hematoma developed, with the patient complaining of pain radiating to the S1 dermatome and saddle paresthesia. The hematoma was surgically decompressed, and the patient had a complete recovery. DISCUSSION: To our knowledge, this is the first report of a spinal epidural hematoma after pelvic ring fracture. The etiology of spinal epidural hematoma is diverse, but it is most frequently observed after spinal surgery. It has rarely been observed after lumbar spinal fractures, nearly exclusively in patients with ankylosing spondylitis. CONCLUSION: Pelvic ring fracture might result in spinal epidural hematoma. The presence of neurological deficits after such fractures is an indication for lumbosacral MRI. Surgical decompression will generally resolve the neurological symptoms.

Severe Symptomatic Epidural Hematoma Following Percutaneous Endoscopic Unilateral Laminectomy for Bilateral Decompression (Endo-ULBD)-Series Report and Management Strategies.

OBJECTIVES: Severe symptomatic epidural hematoma (SSEH) is one of the most severe complications following percutaneous endoscopic unilateral laminectomy for bilateral decompression (Endo-ULBD). Considering that this technique has been performed for a short time, no detailed reports have been recently published. Thus, it is critical to gain a better understanding of SSEH occurring in its postoperative period with regard to its incidence, possible causes, outcome, etc., in order to identify relevant management strategies. METHODS: Patients with spinal stenosis who had undergone Endo-ULBD in our department from May 2019 to May 2022 were retrospectively analyzed. Of which, patients with postoperative epidural hematoma were followed-up. The preoperative and postoperative physical conditions of each patient were recorded, and the information related to hematoma removal surgery was recorded in detail. Clinical outcomes were assessed using the visual analogue scale (VAS) and Oswestry disability index (ODI), and the results were classified into "excellent," "good," "fair," or "poor" based on the modified MacNab criteria. The incidence of hematoma with different factors was calculated, and a bar graph was used to compare the difference of the indexes related to hematoma removal between cases, and a line graph was used to reflect the trend of the outcome of each patient within 6 months to evaluate the effect of the treatment. RESULTS: A total of 461 patients with spinal stenosis who underwent Endo-ULBD were enrolled in the study. SSEH occurred in four cases, with an incidence rate of 0.87% (4/461). All these four patients underwent decompression of multiple segments, and three of them had a history of hypertension comorbid with diabetes. Notably, one patient had a past history of hypertension and coronary artery disease and was on postoperative low molecular heparin due to lower extremity venous thrombosis. According to the conditions of the four patients, three types of treatment were used. And with timely treatment, all patients recovered well. CONCLUSION: Despite being a minimally invasive technique, postoperative epidural hematoma remains a severe complication of Endo-ULBD. Therefore, during percutaneous endoscopic surgery, it is essential to enhance the comprehensive perioperative management of patients with Endo-ULBD. Signs related to postoperative hematoma must be recognized and promptly managed. If necessary, satisfactory results can be achieved by using percutaneous endoscopy along the original surgical channel to remove the hematoma.

Progressive unilateral leg weakness after lumbar decompression due to ischemic monomelic neuropathy misdiagnosed as epidural hematoma: A CARE-compliant case report.

RATIONALE: Ischemic monomelic neuropathy (IMN) is a disease that occurs after acute arterial occlusion or steal phenomenon in an extremity that results in single or multiple axonal mononeuropathies in the distal limb without the classical features of limb ischemia, including a skin color change, limb swelling, and ischemic claudication. IMN can easily be misdiagnosed as any other neuropathic disorder. Here we present a case of IMN that was misdiagnosed as spinal epidural hematoma. PATIENT CONCERNS: A 77-year-old man presented with sudden motor weakness and pain in his left foot and calf 5 days after a bilateral L4 to 5 posterior decompression for lumbar spinal stenosis. His symptoms progressed over the next 5 days. The strengths of the left ankle dorsiflexors, first toe extensors, and ankle plantar flexors were Medical Research Council 0. On brain and whole-spine magnetic resonance imaging, no specific abnormalities correlated with his symptoms were observed. Computed tomography angiography of the lower extremities revealed segmental occlusion of the left common femoral artery and multifocal severe stenoses in the bilateral anterior and posterior tibial arteries of the left leg. No skin color change or swelling was observed in the left lower extremity. DIAGNOSIS: Based on his clinical features and imaging findings, he was diagnosed with IMN. INTERVENTION: The patient underwent thrombectomy of the left femoral artery. OUTCOMES: After the treatment, his pain almost completely disappeared. LESSONS: When patients exhibit acute-onset pain in the unilateral limb with or without motor weakness but no correlated abnormality on spinal magnetic resonance imaging or computed tomography, clinicians should consider the possibility of IMN.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Spontaneous spinal epidural hematoma in a toddler presenting with torticollis: case report and literature review.

INTRODUCTION: Spontaneous spinal epidural hematoma (SSEH) is a rare entity, especially in toddlers and infants. The nonspecificity of its presenting symptoms in children may be a source of delayed diagnosis. CASE DESCRIPTION: We report the case of a 20-month-old young boy without medical history who presented with irreducible torticollis, worsened a few days later by severe tetraplegia and respiratory distress. Spinal magnetic resonance imaging (MRI) showed a posterior epidural hematoma, extending from C3 to T1 and compressing the spinal cord. An urgent decompressive surgery via an extensive laminectomy and evacuation of the clot was performed. The patient demonstrated a partial neurological recovery on follow-up. CONCLUSION: SSEH is a rare and serious condition that may compromise the functional and vital prognosis of the patient, hence the importance of prompt diagnosis and urgent treatment.

Minimally invasive puncture with twist intraosseous drill needle combined with hematoma drainage in the treatment of acute epidural hematoma in pediatric patients: A technical note.

OBJECTIVE: The current neurosurgical intervention for treatment of acute epidural hematoma (AEDH) usually involves a craniotomy. Despite its effectiveness, open surgical decompression has several limitations. The twist intraosseous drill needle (TIDN) is considered a feasible alternative in adult patients with AEDH. AEDH treatment with TIDN in pediatric patients has not yet been described. The study aimed to report the efficacy and safety of minimally invasive puncture with a TIDN combined with hematoma drainage for the treatment of AEDH in pediatric patients. METHODS: We retrospectively collected medical records of children with AEDH who underwent TIDN surgery at our institution from January 2017 to May 2021, and analyzed their clinical and imaging results. A detailed step-by-step surgical guide was provided. RESULTS: Three pediatric patients with AEDH received TIDN treatment (including two males and one female; average age 7.66 years, range from 5 to 11 years). There were no intraoperative or postoperative complications in any case; 1 day after the operation, the AEDH was cleared in one of the three patients, and a slight hematoma remained in two patients. The remaining hematoma was evacuated after injecting urokinase into the hematoma cavity during indwelling drainage. CONCLUSION: For pediatric patients with AEDH in a stable condition with a clear consciousness, TIDN puncture combined with hematoma drainage is safe, effective, and less invasive, and may present a viable surgical alternative option.

Prognostic Factors for Surgically Managed Spontaneous Spinal Epidural Hematoma: A Single-Center Case Series of 18 Patients.

BACKGROUND: Spontaneous spinal epidural hematoma (SSEH) is a rare pathology, which carries a significant morbidity. OBJECTIVE: To review our institutional experience of surgically managed patients with SSEH, seeking to better understand clinical prognostic factors related to postoperative outcomes and thereby improve counseling of patients before treatment. METHODS: All patients who underwent surgical management of SSEH between September 2011 and 2021. Baseline and postoperative clinical and radiological characteristics are presented, including the American Spinal Injury Association grade (ASIA). Statistical analyses were performed using Stata 13.1. RESULTS: Eighteen patients were identified in total (11 male patients and 7 female patients) with a median age of 59.5 (range 3-83) years. The most common spinal region affected was cervicothoracic (33.3%). Limb weakness (94.4%) and urinary dysfunction (83.3%) represented the most common presenting symptoms. Preoperatively, the presence of spinal cord edema on imaging was associated with worse preoperative Medical Research Council (MRC) grade ( P = .033), female sex was associated with preserved saddle sensation ( P = .04), and patients receiving antiplatelet medication were associated with a higher risk of preoperative axial back pain ( P = .005). Higher postoperative MRC grade was associated with higher preoperative ASIA ( P = .012) and MRC grade ( P = .005), and preservation of saddle sensation ( P = .018). Postoperative improvements in axial back pain were associated with higher preoperative ASIA grade ( P = .035) and anticoagulation treatment ( P = .029). CONCLUSION: Neurosurgical intervention for SSEH yields positive outcomes and benefits patients. Patients with higher preoperative ASIA, MRC grade, and those presenting with preserved saddle sensation may experience further improved clinical outcomes after intervention.

Ultraearly Hematoma Evacuation (<12 Hours) Associated with Better Functional Outcome in Patients with Symptomatic Spontaneous Spinal Epidural Hematoma.

BACKGROUND: Early decompressive surgery within 24 hours improves the functional outcome of patients with traumatic spinal cord injury; however, little is known about the effect of early surgery for spontaneous spinal epidural hematoma (SSEH). In this study, we aimed to investigate the effectiveness of ultraearly hematoma evacuation (<12 hours) for SSEH. METHODS: Patients with SSEH treated with surgical hematoma evacuation at our institution between January 2000 and July 2021 were retrospectively analyzed. Neurologic function was evaluated using the American Spinal Injury Association Impairment Scale (AIS). AIS grades A-C were defined as severe, and grades D and E as mild. AIS grades D and E at the final follow-up were considered favorable outcomes. Preoperative status and postoperative treatment results were compared between patients who had hematoma evacuation within 12 hours of onset and those who underwent surgery after 12 hours. RESULTS: Twenty-five consecutive patients were included in the analysis. Preoperatively, 23 patients (92.0%) had severe AIS. Fourteen (56.0%) patients underwent early surgery. At the final follow-up, 21 patients (84.0%) achieved favorable outcomes. Patients treated with ultraearly surgery had significantly better outcomes (100% vs. 63.6%, P = 0.03). Additionally, the time from onset to surgery was significantly shorter in patients with AIS improvement by 2 or more grades than that in patients with AIS improvement of 1 or less (median 8 hours vs. 14 hours, P = 0.0001). CONCLUSIONS: Ultraearly surgery within 12 hours for SSEH was associated with better functional outcomes.

Prognosis and outcome of chronic pain after spontaneous spinal epidural hematoma.

OBJECTIVE: Chronic pain is a common symptom experienced by patients after spontaneous epidural hematoma (SSEH), and it seriously affects their quality of life. The outcome and prognosis of chronic pain after SSEH are rarely reported. Thus, we conduct this study to present the outcomes and explore prognostic factors of chronic pain in patients with SSEH. METHODS: We retrospectively reviewed patients diagnosed with SSEH and invited them to complete the American Spinal Injury Association (ASIA) and Neuropathic Pain Symptom Inventory (NPSI) scales. Pearson χ2 and binary logistic regression were used to explore prognostic factors related to chronic pain after SSEH. RESULTS: A total of 55 patients were reviewed; 21 patients (38.2%) were lost to follow-up, 3 patients (5.4%) died, and 31 patients (56.4%) completed the scales, with a mean follow-up time of 20.6 ± 17.3 months. The ASIA and NPSI results showed significant improvement after surgery. Pearson χ2 showed that timely surgery (≤ 12 h) was related to better outcomes (p < 0.05, Fisher test), and binary logistic regression revealed that patients with a preoperative NPSI score of 11-20 were prone to achieving significant pain relief (OR 23.67, 95%CI 1.11-503.48, p = 0.04). CONCLUSION: Chronic pain is a common symptom during follow-up after SSEH, and timely intervention is suggested to obtain satisfactory outcomes. Patients who receive emergent surgery within 12 h or who have a preoperative NPSI score of 11-20 may achieve significant relief of chronic pain.

Unique case of successful surgical treatment of recurrent spinal epidural hematoma after lumbar disc surgery in a Glanzmann thrombasthenia patient.

We report a case of recurrent postoperative spinal hemorrhage after lumbar disc surgery in a Glanzmann thrombasthenia patient.

Traumatic acute convexity interdural hematoma: a case report and literature review.

INTRODUCTION: Interdural hematoma (IDH) is an extremely rare hemorrhage between the outer periosteal dura mater and the inner meningeal dura mater. There are 8 cases of convexity IDH reported previously but none of them were acute post traumatic one. We report the case of a patient with an initial diagnosis of acute epidural hematoma (EDH) that was eventually revealed to be an acute convexity IDH. CASE REPORT: A 57-year-old man presented to the emergency department with a complaint of falling from 2 meters. Imaging findings revealed an expanding intracranial hematoma with a linear skull fracture extending to sagittal suture, which was mistaken as an EDH. Emergent surgical evacuation was performed; the hematoma was lodged between two dural layers. DISCUSSION: This is the first case of acute convexity IDH following trauma that has been reported. In chronic and sub-acute hematomas MRI scans could be very useful, but in acute cases under emergent circumstances, CT scan cannot make a proper differentiation between an EDH and IDH. IDH should be considered during craniotomy when extradural findings do not explain the CT scan findings. This case showed a linear skull fracture expanding to the sagittal suture, and this can be a possible explanation for IDH formation. Surgical evacuation of the hematoma without inner nor outer layer resection and leaving the outer layer open, to connect the interdural space to epidural space was first described in this report.

Complications of Unilateral Biportal Endoscopic Spinal Surgery for Lumbar Spinal Stenosis: A Meta-Analysis and Systematic Review.

BACKGROUND: In recent years, unilateral biportal endoscopic spinal surgery has been used for the treatment of lumbar spinal stenosis with good results. Some investigators counted the total incidence of complications in unilateral biportal endoscopic surgery for lumbar spinal stenosis, but none have analyzed the incidence of specific complications. The present study further counted the incidence of specific complications and gave the possible causes of the complications. METHODS: English databases including PubMed were searched to collect relevant literature on unilateral biportal endoscopic spinal surgery for lumbar spinal stenosis. The inquiry period is from January 1, 2015, to July 1, 2022. The literature was screened, information extracted, and risk of bias evaluated by the researchers, followed by Meta analysis using R4.2.1 and RStudio statistical software. RESULTS: In total, we included 14 studies involving 707 patients. The included studies were retrospective case series, The results of the single-arm rate meta-analysis showed that the total complication rate of unilateral biportal endoscopic surgery treatment of lumbar spinal stenosis was 8.1% (95% confidence interval [CI] [0.060; 0.103]); of which, the highest incidence of dural tear was 4.5% (95% CI [0.030; 0.064]), the incidence of symptomatic postoperative spinal epidural hematoma was approximately 1.1% (95% CI [0.001; 0.027]), the incidence of incomplete decompression was 2.0% (95% CI [0.007; 0.038]), the incidence of transient palsy was 2.6% (95% CI [0.005; 0.057]). CONCLUSIONS: The incidence of total complications of unilateral biportal endoscopic surgery for lumbar spinal stenosis was 8.1%, dural tear remained a major complication with an incidence of 4.5%, incomplete decompression was 2.0%, transient palsy was 2.6%, and, unexpectedly, symptomatic postoperative spinal epidural hematoma was only 1.1%.

Emergency surgical decompression for spontaneous spinal epidural hematoma in octogenarians: risk factors, clinical outcomes, and complications.

PURPOSE: Spontaneous spinal epidural hematoma (SSEH) is a rare but disabling disease. Although several cases have been reported in the literature, their treatment remains unclear, especially in patients with advanced age. We, therefore, aimed to describe the clinical outcomes of cervical SSEH in octogenarians with an acute onset of neurological illness undergoing laminectomy. METHODS: Electronic medical records from a single institution between September 2005 and December 2020 were retrieved. Data on patient demographics, neurological conditions, functional status, surgical characteristics, complications, hospital course, and 90-day mortality were also collected. RESULTS: Twenty-two patients aged ≥ 80 years with SSEH undergoing laminectomy were enrolled in this study. The mean Charlson comorbidity index was 9.1 ± 2.0, indicating a poor baseline reserve. Ten individuals (45.5%) were taking anticoagulant agents with a pathologic partial thromboplastin time (PTT) of 46.5 ± 3.4 s. Progressive neurological decline, as defined by the motor score (MS), was observed on admission (63.8 ± 14.0). The in-hospital and 90-day mortality were 4.5% and 9.1%, respectively. Notably, the MS (93.6 ± 8.3) improved significantly after surgery (p < 0.05). Revision surgery was necessary in 5 cases due to recurrent hematoma. Anticoagulant agents and pathological PTT are significant risk factors for its occurrence. Motor weakness and comorbidities were unique risk factors for loss of ambulation. CONCLUSIONS: Laminectomy and evacuation of the hematoma in octogenarians with progressive neurological decline induce clinical benefits. Emergent surgery seems to be the "state of the art" treatment for SSEH. However, potential complications associated with adverse prognostic factors, such as the use of anticoagulants, should be considered.

Evacuation of a spontaneous massive spinal epidural hematoma by a minimally invasive surgical technique: a case report.

Spontaneous spinal epidural hematomas are a rare consequence of long-term anticoagulant therapy. Their physiopathology remains poorly understood. This pathology carries a significant risk of morbidity. The purpose of this article is to report a case of a massive spontaneous spinal epidural hematoma extending on multiple levels, detailing the surgical technique used in its evacuation described for the first time in literature. This is a case report of an 80-year-old patient on anticoagulant therapy with a thoracolumbar spontaneous spinal epidural hematoma extending from T1 to L1 vertebrae. We share the clinical and radiological presentations, the surgical treatment, outcome and follow-up. The diagnosis of spontaneous spinal epidural hematoma has to be considered in patients with acute brutal onset radiculo-medullary compression. Medullary magnetic resonance imaging (MRI) remains the exam of choice. Medical and surgical treatment must be started immediately after the diagnosis is confirmed. The prognosis remains poor despite a proper management, with debilitating complications.
