Management and neurological outcome of spontaneous spinal epidural 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.

Clinical outcome after surgical management of spontaneous spinal epidural hematoma

PURPOSE

Spontaneous 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.

METHODS

Patients 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.

RESULTS

In 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.

CONCLUSION

Early surgical evacuation of SSEH generally leads to favorable clinical outcomes. Surgical hematoma evacuation should be indicated in all patients with symptomatic SSEH.

A Rare Case of a Spontaneous Thoracic Epidural Hematoma in a Young Male Weightlifter

Spontaneous spinal epidural hematoma (SSEH) is the accumulation of blood in the epidural space of the spinal cord. Acute SSEH is a rare phenomenon that presents with a wide variety of neurologic symptoms and most often is a surgical emergency. We present a previously healthy 34-year-old male with sudden onset progressive weakness and tingling in the right lower extremity that progressed to the left lower extremity while bench pressing weights, resulting in complete lower extremity paralysis. Magnetic resonance imaging (MRI) revealed a 3.0 cm extradural mass centered in the dorsal and left lateral canal. After a T1-T4 hemilaminectomy was performed which was followed by inpatient rehabilitation, the patient had a favorable outcome improving from The American Spinal Injury Association Impairment Scale (AIS) grade A, complete impairment, to AIS grade C, incomplete impairment on discharge. Initially, the patient had complete motor and sensory paralysis below the level of T4, and upon discharge, the patient was able to attain modified independence in activities of daily living, mobility, and transfer. Due to the lack of risk factors for SSEH in this patient, the etiology is most likely related to the Valsalva maneuver while weightlifting. Lesions in the thoracic region with rapid progression of neurologic symptoms are indicators of poor prognosis, so this case highlights the importance of prompt recognition and intervention for improved outcomes to prevent devastating neurologic defects.

Two pediatric observations of spinal extradural arteriovenous fistulas presenting with epidural hemorrhages and cord compression

We report two cases of acute spinal cord compression in children with low-flow spinal epidural arteriovenous fistulas (SEAVFs) and discuss the clinical presentation and management of these vascular anomalies. While most low-flow SEAVFs without radiculomedullary drainage are benign lesions typically diagnosed incidentally, we suggest that asymptomatic lesions may warrant aggressive management in specific circumstances, including lesions diagnosed at an early age or in patients under anticoagulation therapy. Our observations also emphasize that patients with a "spontaneous" epidural hemorrhage should undergo dedicated preoperative or postoperative vascular imaging to identify a possible underlying vascular anomaly.

Spontaneous spinal epidural hematoma leading to acute paraplegia: a case report

BACKGROUND

Spontaneous spinal epidural hematoma is an infrequent yet potentially debilitating condition characterized by blood accumulation in the epidural space, with only 300 documented cases globally. Although the exact etiology of spontaneous spinal epidural hematoma remains poorly understood, theories suggest arteriovenous malformations, rupture of epidural vessels, or epidural veins as possible causes.

CASE PRESENTATION

This study presents a 58-year-old Malay woman patient from Singapore with well-controlled hypertension, hyperlipidemia, type II diabetes mellitus, and microscopic hematuria. Despite a prior cystoscopy revealing no abnormalities, she presented to the emergency department with sudden-onset back pain, weakness, and numbness in both lower limbs. Rapidly progressing symptoms prompted imaging, leading to the diagnosis of a spinal epidural hematoma from thoracic (T) 9 to lumbar (L) 1. Prompt decompressive surgery was performed, and the patient is currently undergoing postoperative rehabilitation for paralysis.

CONCLUSION

This case emphasizes the severity and life-altering consequences of spontaneous spinal epidural hematomas. Despite various proposed causative factors, a definitive consensus remains elusive in current literature. Consequently, maintaining a low threshold of suspicion for patients with similar presentations is crucial. The findings underscore the urgent need for swift evaluation and surgical intervention in cases of acute paraplegia.

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.

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.

Neurological severity evaluation using magnetic resonance imaging in acute spontaneous spinal epidural haematomas

PURPOSE

This study aimed to elucidate the severity of neurological deficits in a large series of patients with acute spontaneous spinal epidural haematoma (SSEH) using magnetic resonance imaging (MRI).

METHODS

We included 57 patients treated for acute SSEH at 11 institutions and retrospectively analysed their demographic and MRI data upon admission. We investigated MRI findings, such as the haematoma length and canal occupation ratio (COR). The neurological severity of SSEH was assessed based on the American Spinal Injury Association score on admission.

RESULTS

Of the 57 patients, 35 (61%) presented with severe paralysis. The MRI analysis showed that SSEH was often located in the cervical spine, dorsal to the spinal cord, and spread over more than three vertebrae. No differences in age, sex, and aetiology were found between patients with and without severe paralysis. The hypo-intensity layer encircling the haematoma, intra-haematoma heterogeneity, and increased CORs were observed more frequently in the severe paralysis group. Furthermore, pathological examination of a dissected haematoma from one patient with a hypo-intensity layer revealed a collagen layer around the haematoma, and patients with intra-haematoma heterogeneity were more likely to have a bleeding predisposition.

CONCLUSIONS

In this large series of patients with SSEH, we identified some MRI features associated with severe paralysis, such as the hypo-intensity layer, intra-haematoma heterogeneity, and increased COR. Accordingly, patients with these MRI characteristics should be considered for early surgical intervention.

Spontaneous Spinal Epidural Hematoma Associated With Short-Term Dual Antiplatelet Therapy: A Case Report

Spinal epidural hematoma (SEDH), either spontaneous or traumatic, is a rare neurosurgical emergency. Typically, the natural history is a sudden onset of severe neck or back pain, associated with neurological deficit, either immediately or after a short period of the pain onset. MRI is the gold standard investigation. The mainstay of treatment is spinal decompression, in the form of laminectomy or hemilaminectomy, with the evacuation of the hematoma. The occurrence of SEDH has been strongly associated with coagulopathy, especially that induced by anticoagulant use. The association between SEDH and antiplatelet therapy has been scarcely reported in the literature. We report a case of spontaneous SEDH in a patient who was on dual antiplatelet therapy. Our case is unique because the patient had been using antiplatelet agents for only six weeks prior to this diagnosis. As antiplatelet agents are widely prescribed, physicians should be able to anticipate SEDH as a possible complication of dual antiplatelet therapy to facilitate early treatment and better outcomes.

Prognostic factors for spontaneous spinal epidural hematoma: a multicenter case-control study

BACKGROUND

To determine the optimal treatment for spontaneous spinal epidural hematoma (SSEH). The aim of this study was to identify factors associated with SSEH.

METHODS

In 62 patients with SSEH, several patient-related parameters were analyzed as candidate factors associated with Frankel grade before treatment or at the last follow-up. These parameters were compared between patients with and without surgery. In addition, multivariate ordinal logistic regression analysis was used to identify factors significantly associated with Frankel's grade before treatment or at the last follow-up.

RESULTS

There were significant differences in age, location of the hematoma, and Frankel grade before treatment and at the last follow-up between surgical and nonsurgical cases in all patients, but there were no significant differences in any of these parameters when comparing patients with pre-treatment Frankel grade C. The location of the hematoma was significantly associated with the severity of paralysis before treatment. In surgical cases, the time from onset to surgery and the location of the hematoma was significantly associated with the prognosis. When the time from onset to surgery was evaluated using the criteria of 12, 24, and 48 h, 24 and 48 h had a significant impact on the prognosis. In the analysis of nonsurgical cases, only the vertical size of the hematoma was significantly associated with prognosis.

CONCLUSION

The time from onset to surgery and the location of the hematoma were prognostic factors in surgical cases, while the vertical size of the hematoma was a prognostic factor in nonsurgical cases.

A Rare Presentation of Spontaneous Spinal Epidural Hematoma as Spinal Cord Compression and Complete Paraplegia: A Case Report and Review of the Literature

Spontaneous spinal epidural hematoma (SSEH) is a serious but infrequent cause of profound neurological compromise of acute onset. It is often an atraumatic occurrence, and in around half of the cases, no etiology is identified. However, several causes such as arteriovenous malformation in the spine, use of anticoagulants in various cardiovascular diseases, and spinal trauma have been incriminated for its development. Here we encountered a case of SSEH following unregulated use of anticoagulants after a mitral valve replacement surgery. The patient had complete paraplegia with bowel and bladder involvement. The case was treated with decompressive laminectomy with regularization of her coagulation profile. Although she presented late to the healthcare center for the treatment, she showed a remarkable neurological improvement with gaining power worth near independent ambulation after one year of follow-up.

Spontaneous spinal epidural hematoma in a patient on acenocoumarol for valvular atrial fibrillation: A rare case report

INTRODUCTION

Spontaneous spinal epidural hematoma (SSEH) is a rare finding, but one with serious clinical implications. Oral anticoagulant drugs are known to be associated with the SSEH onset, particularly when combined with drugs increasing the bleeding risk.

CASE PRESENTATION

We present the case of a 62-year-old female on acencoumarol for her atrial fibrillation complicating severe mitral stenosis with a history of Ketoprofen use for the onset of her first symptoms. She presented to our emergency room with paraplegia and sphincter disturbance. Spinal magnetic resonance imaging (MRI) revealed a posterior SSEH extended from T10 to T12 requiring an urgent decompression of the spinal cord by laminectomy performed within 48 hours from the symptom's onset. After 3 months of rehabilitation, the patient improves partially her muscular strength with mostly unchanged sensitive and sphincteric levels.

CLINICAL DISCUSSION

Vitamin K antagonists (VKA) use appears to be a high suspicion index for SSEH diagnosis resulting in earlier surgery and improving neurological outcome. Also, it is important to pay attention to the concomitant use of VKA and non-steroidal anti-inflammatory drugs which increase the risk of bleeding and may worsen the neurological outcome.

CONCLUSION

SSEH is a rare and serious finding which should be especially searched when a history of oral anticoagulation is reported in presence of neurological symptoms. A prompt and suitable management may improve the patient outcomes.

A rare case of spontaneous spinal epidural hematoma in a 43-year-old man

Spontaneous spinal epidural hematoma is a rare neurosurgical condition that is often difficult to diagnose in the emergency department and can cause permanent neurological deficits if diagnosis is delayed or incorrect. We present the case of a 43-year-old man who was initially investigated for cardiac events, suspected posterior circulation stroke, or arterial dissection. All investigations were normal, which led us to perform magnetic resonance imaging of the brain, neck, and cervicothoracic spine, which revealed spontaneous spinal epidural hematoma. Publication of this case raises awareness of this rare neurosurgical emergency and the importance of differential diagnosis to avoid misdiagnosis in patients presenting with sudden-onset cervicothoracic back pain radiating to the upper limbs bilaterally with neurological deficit and a history of discectomy or receiving anticoagulants. Our study highlights the importance of early discussions with the consultant and specialty involvement in such cases.

Spontaneous Spinal Epidural Hematoma in an Adult Patient with Complex Congenital Heart Disease

Spontaneous spinal epidural hematoma (SSEH) is considered to be a relatively rare disease that can result in serious neurological sequelae. The pathogenesis and risk factors of SSEH are still unknown, and its differential diagnosis varies widely. Misdiagnosis with more common conditions such as stroke or aortic syndromes can occur. We report the case of a 27-year-old man who developed sudden upper back pain with no specific precipitant. Five days later, he visited our emergency department complaining of weakness in both lower limbs and dysuria. He had a history of intracardiac repair and a Blalock-Park procedure for an interrupted aortic arch and ventricular septal defect in infancy. Additionally, he had undergone an aortic root dilatation and aortic valve replacement at the age of 10 because of progression of aortic and supra-aortic stenosis and had received chronic anticoagulation and antiplatelet therapy with warfarin and aspirin, respectively. An emergency spine magnetic resonance imaging scan indicated a mass at the Th3-Th5 level with severe compression of the dural sac and the spinal cord. Emergency excision showed a spinal epidural hematoma. Mild postoperative gait disturbance and dysuria persisted, requiring rehabilitation and intermittent self-urethral catheterization. As patients with adult congenital heart disease have an increased risk of bleeding, they may be at risk of developing SSEH. However, this is the first report to describe such an association.

Therapeutic strategy for acute spinal cord paralysis by epidural hematoma derived from the application of non-operative observation and the optimal timing to convert to surgical intervention

Some cases of acute spinal cord paralysis by epidural hematoma have made complete recovery through natural progression. This group cannot be ignored in choosing a therapy. We have considered the applications of non-operative observation and the optimal timing to convert to surgical intervention. Of the 454 cases reported, cases that were of trauma/post-operative, undergone epidural block, lumbosacral level, paralysis-free, were excluded. 10 clinical items were identified as factors related to the outcome of therapy, and a total of 142 cases (73 surgical and 69 non-surgical/observation cases) which included all items in its record, were extracted for this study. 104 cases that made complete recovery from spinal paralysis (CR) includes 65 cases without surgical intervention (NOP-CR). Using "paralysis recovery start time (PRST)", ROC analysis was conducted to show the diagnostic time needed to detect the cases of CR and NOP-CR. Clinical characteristics of CR and NOP-CR were identified using multiple logistics regression analysis. CR probability were higher at PRST < 15 h from the onset and NOP-CR was even higher at < 11 h. Three clinical items: incomplete motor paralysis, no use of anti-coagulant therapy, and PRST within 15 h were found to be the characteristics of CR and NOP-CR. The case with all 3 items; especially PRST within 11 h from onset, is applicable to non-operative observation. Immediate surgical intervention at 6-hours is recommended in cases that presented with unchanged complete motor paralysis. Observation treatment is discontinued and converted to surgery if motor usefulness is not regained at 15-hours.

A spontaneous cervical spinal epidural hematoma in a male patient receiving treatment for acute coronary syndrome: A case report

Although spontaneous spinal epidural hematoma is a rare entity with an unknown origin, it may occur secondary to the use of anticoagulant and/or antiplatelet agents, which are particularly used for the treatment of cardiovascular and cerebrovascular diseases. Since it occurs rarely and its initial symptoms are usually non-specific, early and accurate diagnosis can be challenging which affects survival rate and the quality of life. Herein, we present a 65-year-old male case who developed acute severe neck pain and headache on the third day of acute coronary syndrome treatment, followed by neurological deficits in bilateral upper and lower extremities.

Spontaneous spinal epidural hematoma masquerading as atypical abdominal pain in a child: A case report

INTRODUCTION

There have been few case reports of abdominal pain as a symptom of spontaneous intraspinal hemorrhage. We herein describe a case involving a girl with paraplegia caused by spontaneous epidural hemorrhage in the thoracic spinal canal, characterized by abdominal pain.

PATIENT CONCERNS

An 8-year-old girl with sudden abdominal pain and back pain was misdiagnosed as having an abdominal disease until she had the symptom of paralysis.

DIAGNOSES

The patient was diagnosed with spontaneous intraspinal hemorrhage masquerading as atypical abdominal pain.

INTERVENTIONS

When the patient developed symptoms of lower extremity paralysis, thoracic magnetic resonance imaging was performed and epidural hemorrhage was found in the thoracic spinal canal. Surgical treatment was performed after the diagnosis was confirmed.

OUTCOMES

The patient could almost walk normally after 3 months. One year after surgery, the Frankel grade of spinal cord function was grade D. We continued to follow-up this patient.

CONCLUSION

The symptoms caused by intraspinal hemorrhage are mainly back pain with or without neurological dysfunction. However, sometimes atypical symptoms, such as abdominal and chest pain, can be identified in clinical settings. Emergency surgery is recommended as the treatment of choice for intraspinal hemorrhage with neurological dysfunction.

Vascular Disorders of the Spinal Cord

PURPOSE OF REVIEW

Prompt recognition and timely management of vascular disorders of the spinal cord can improve patient outcomes. This article provides contemporary and practical knowledge about the most common vascular myelopathies.

RECENT FINDINGS

New studies have provided additional information on the risk factors and impact of neurologic monitoring on perioperative spinal cord infarction. Additionally, recent publications have provided information on the impact of misdiagnosis, corticosteroid treatment, and postoperative prognosis in the treatment of spinal dural arteriovenous fistulas and have discussed the outcome of patients with spinal arteriovenous malformations treated with embolization, surgery, and stereotactic radiosurgery. Finally, recent studies have provided information on the natural history and postoperative prognosis of spinal cavernous malformations and on the risk factors and surgical outcome of patients with spinal epidural hematomas.

SUMMARY

Diagnostic and therapeutic challenges are inherent in managing patients with vascular disorders of the spinal cord, and clinicians should have a thorough understanding of these disorders to facilitate optimal outcomes for patients with these potentially devastating illnesses. This article begins by reviewing functional vascular anatomy and subsequently describes the fundamental characteristics of both ischemic and hemorrhagic vascular myelopathies to equip clinicians with the knowledge to avoid common pitfalls.

A Spontaneous Cervical Epidural Hematoma Mimicking a Stroke: A Challenging Case

BACKGROUND

A spontaneous cervical epidural hematoma (SCEH) is a rare occurrence, with < 500 cases reported to date. Clinically, it usually presents with quadriparesis, but in extremely rare cases it can present with hemiparesis or hemiplegia, and can easily be misdiagnosed as stroke. The cervical epidural hematoma by itself is an urgent condition that requires a quick and accurate diagnosis and a prompt surgical treatment.

CASE REPORT

We present a case where an SCEH mimicked the much more frequent condition of a stroke, and discuss the importance of diagnostics procedures that help differentiate SCEH from acute cerebral infarction. The patient's history of neck pain and spondylosis render this case more challenging. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Considering that the emergency tissue plasminogen activator treatment for acute cerebral infarction can worsen the state of an SCEH patient, or even lead to permanent damage or death, it is of great importance to rapidly and accurately differentiate these two conditions.

Spontaneous spinal epidural hemorrhage following disseminated intravascular coagulation resulting in paraplegia: a case report

CONTEXT

Spontaneous spinal epidural hemorrhage (SSEH) mostly presents as low back pain with or without a radiculopathy, and rarely with paraplegia or tetraplegia depending on the site and severity of spinal cord compression. We present here a case who had anemia and developed paraplegia following disseminated intravascular coagulation (DIC) due to a transfusion reaction.

FINDINGS

A 65-year-old lady presented with sudden onset chest pain radiating to nape of the neck followed by loss of sensations and power in legs few hours after a blood transfusion. Her past history was negative for diabetes mellitus, hypertension, coronary artery disease, or a bleeding disorder. Her blood pressure was 90/57 mmHg and she had a normal pulse, respiratory rate, and temperature. On neurological examination, she had no motor power and unevokable muscle stretch reflexes in the lower limbs. The sensations were intact till T₃ dermatome. The laboratory evaluation was suggestive of DIC. The magnetic resonance imaging showed a non-enhancing abnormal signal intensity area in the posterior epidural space, extending from CV₄ to LV₄ causing cervico-dorsal cord compression associated with cord edema. Following diagnosis, urgent decompressive surgery was carried out due to deteriorating neurological status. The patient was transfused with five bags of red cell concentrate, two bags of platelets, and four bags of fresh frozen plasma during the operation. The patient regained consciousness following operation, however, the neurological status did not improve. She, unfortunately, died on the third post-op day due to cardiac arrest.

CONCLUSION

SSEH is a rare cause of paraplegia. Early radiological diagnosis is crucial for timely neurosurgical management and saving patient from permanent neurological deficit or a fatal outcome.

Spontaneous Spinal Haemorrhage as a Complication of Oral Anticoagulant Therapy: A Case Report and Literature Review

Spinal cord haematoma, or haematomyelia, is a rare condition caused by several unusual disease processes. Traumatic events, such as spinal cord injury and surgery or procedures involving the spinal cord, are the most important causes of spinal cord haematoma. Rarely, it is associated with anticoagulation therapy. Irrespective of cause, spinal cord haematoma is considered a neurosurgical emergency and must be treated promptly in order to prevent neurological sequelae. The authors describe the case of a 69-year-old patient taking warfarin in the therapeutic range for a mechanic mitral valve, who developed chest pain with cervical and dorsal radiation, and experienced sudden paraparesis of the limbs. A CT of the spine confirmed haematomyelia. A high index of suspicion, prompt recognition and immediate intervention are essential to prevent major morbidity and mortality from intraspinal haemorrhage.

LEARNING POINTS

This article reports an unusual presentation of spontaneous spinal haematoma, imposing the careful elaboration of differential diagnoses, which is very important in internal medicine.The description of this low-incidence case allows the scientific community to assist in approaching patients with similar symptoms.The lack of studies about the etiology and treatment of spontaneous spinal haematoma underlines the need for further studies and research in the area in order to increase the scientific evidence on the approach of these patients.

Imaging of Acute Low Back Pain

Acute low back pain, defined as less than 6 weeks in duration, does not require imaging in the absence of "red flags" that may indicate a cause, such as fracture, infection, or malignancy. When imaging is indicated, it is important to rule out a host of abnormalities that may be responsible for the pain and any associated symptoms. A common mnemonic VINDICATE can help ensure a thorough consideration of the possible causes.

Spontaneous Spinal Epidural Hematoma: A Case Report

Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord and leading to acute neurological deficits. MRI provides the most valuable visualization of the location and hematoma mass as well as the presence of the spinal cord compression. SSEH can occur in any segments of the spinal cord but predominantly at the posterior cervicothoracic (C5–T2) and thoracolumbar (T10–L2) levels. The source of hemorrhage SSEH can be both vertebral venous plexus system or arterial source. Decompressive laminectomy and hematoma evacuation are the standard surgical procedures upon diagnosis of SSEH, although spontaneous recoveries have been reported. The degree of preoperative neural deficit is a major prognostic factor. Conservative management has proven effective, although feasible only if spontaneous recovery is manifested. Decompressive laminectomy should continue to remain readily available, given the inverse correlation between operative interval and recovery.

Management and outcomes of spinal epidural hematoma during vertebroplasty: Case series

RATIONALE

Spinal cord injury (SCI) is one of the common complications of spinal surgery. There is no definite treatment and time of decompression for spinal cord induced by epidural hematoma during vertebroplasty.

PATIENT CONCERNS

A total of 6 patients with SCI during vertebroplasty were included in our research. All of them occurred sensory disturbance and motor dysfunction due to a lower or same level operative vertebral body lesion in vertebroplasty.

DIAGNOSES

Neurological manifestations during vertebroplasty, postoperative magnetic resonance imaging and computed tomography.

INTERVENTIONS

Once SCI occurred in vertebroplasty, four patients were underwent spinal cord decompression immediately, and two patients were done after 14 and 22 hours, respectively.

OUTCOMES

Before decompression operation, one patient was Frankel A, three were Frankel B, and two were Frankel C. One day after evacuation of the SEH, three patients recovered to normal neurological function (Frankel E), one to Frankel C, and one to Frankel D, but the other one did not recover. At the last follow-up, five patients had recovered to Frankel E and one patient to Frankel D.

LESSONS

According to our experience, when SCI occurs during vertebroplasty, neurological deficits are always secondary to acute SEH. Timely decompression, particularly transfer surgery, can shorten recovery time.

Hemiparesis in spontaneous spinal epidural haematoma: a potential stroke imitator

Spontaneous spinal epidural haematoma (SSEH) is a rare condition that requires urgent surgical intervention in order to prevent permanent neurological deficit. SSEH commonly presents as a paraparesis or tetraparesis. SSEH presenting as a hemiparesis is less common and in such situations, it can be mistaken for a cerebrovascular accident (CVA). Thrombolytic or anticoagulant treatment for CVA can potentially worsen the neurological deficit. We report one such case of SSEH misdiagnosed as a CVA. Treatment with tissue plasminogen activator led to worsening of his condition. On a subsequent cervical spine MRI, an epidural haematoma extending from C3 to C5 was detected and treated with laminectomy and evacuation. Surgical intervention led to significant improvement from American Spinal Injury Association Scale (ASIA) B to ASIA E. Presence of clinical features such as Horner's syndrome, Brown-Sequard syndrome and the absence of cranial nerve palsies in acute hemiparesis are indicative of SSEH rather than CVA.

Skip Hemilaminectomy for Large, Multilevel Spinal Epidural Hematomas: Report of a Series of 11 Patients

OBJECTIVE

We present our experience with a modification of the conventional techniques for the removal of large spinal epidural hematomas (SEHs), based on multilevel "skip hemilaminectomies."

METHODS

Eleven patients with SEHs extending over 5 or more spinal segments were treated at our institution via a modified hemilaminectomy technique from 2008 to 2014. This procedure, that we called "skip hemilaminectomy," consists in performing consecutive, alternating, unilateral laminar decompressions at 2-3 levels, followed by sublaminar undercutting, ipsi- and contralateral flavectomy, plus hematoma removal.

RESULTS

Complete clot evacuation and full neurologic recovery were always achieved. A short hospital stay, fast postoperative mobilization, a minimized need of analgesic drugs, and no complications were recorded.

CONCLUSIONS

In our preliminary experience, skip hemilaminectomy seems to be as safe as more conventional techniques (laminectomy, extended hemilaminectomy) for the removal of large multilevel SEHs, granting full neurologic improvement, short surgical times-even for very large lesions-and no complications at follow-up.

Nonsurgical management of an extensive spontaneous spinal epidural hematoma causing quadriplegia and respiratory distress in a choledocholithiasis patient: A case report

RATIONALE

Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord, and leading to acute neurological deficits. The disease's cloudy etiology and rarity contribute to dangerously suboptimal therapeutic principles. These neural deficits can be permanent, even fatal, if the SSEH is not treated in a timely and appropriate manner. Standard therapy is decompressive laminectomy, though nonsurgical management is a viable course of action for patients who meet a criterion that is continuously being refined.

PATIENT CONCERNS

A 76-year-old woman on warfarin for a past pulmonary embolism presented to the emergency room with jaundice, myalgia, hematuria, neck pain, and an International Normalized Ratio (INR) of 14. Upon admission, she rapidly developed quadriplegia and respiratory distress that necessitated intubation.

DIAGNOSES

T2-weighted magnetic resonance imaging (MRI) revealed an epidural space-occupying hyperintensity from C2 to S5 consistent with a spinal epidural hematoma. An incidental finding of dilated intrahepatic and common bile ducts prompted an endoscopic retrograde cholangiopancreatography, which demonstrated choledocholithiasis.

INTERVENTIONS

The patient's INR was normalized with Vitamin K and Beriplex. Upon transfer to the surgical spine team for assessment of a possible intervention, the patient began to demonstrate recovery of neural functions. The ensuing sustained motor improvement motivated the team's preference for close neurologic monitoring and continued medical therapy over surgery. Thirteen hours after the onset of her symptoms, the patient was extubated. A sphincterotomy was later performed, removing 81 common bile duct stones.

OUTCOMES

MRI demonstrated complete resorption of the SSEH and the patient maintained full neurological function at final follow-up.

LESSONS

Nonsurgical management of SSEH should be considered in the context of early and sustained recovery. Severe initial neural deficit does not necessitate surgical decompression. Choledocholithiasis and subsequent Vitamin K deficiency, particularly when coupled with anticoagulant use, can increase INR and is a novel proposed risk factor for SSEH. Furthermore, coagulopathies should be medically corrected before surgical intervention within a given timeframe, as spontaneous recovery may manifest. This should be favored over surgery in patients demonstrating early and sustained recovery, as nonsurgical management is 25% more effective in achieving full recovery.

Spontaneous spinal epidural hematoma mimicking transient ischemic attack: A case report

RATIONALE

Spontaneous spinal epidural hematoma (SSEH) is a rare but highly disabling neurological emergency. The initial presentations are variable. Most patients of SSEH present with paraplegia or tetraplegia clinically, but recurrent hemiparesis with complete spontaneous recovery, mimicking transient ischemic attack (TIA), is a very rare initial presentation of SSEH.

PATIENT CONCERNS

A 71-year-old female presented to the emergency department with 2 episodes of transient right hemiparesis in 5 hours. Two days later, above symptom reappeared and progressed to quadriplegia, dyspnea, and uroschesis quickly. The neurological examination showed tetraplegia and hypalgesia below the C2 level, but neither facial palsy nor aphasia was found.

DIAGNOSIS

The patient was initially misdiagnosed as TIA and treated with antiplatelet therapy. But during the hospital day, the cervical magnetic resonance imaging showed a dorsal epidural hematoma extending from C2 to C6 level and she was diagnosed as SSEH.

INTERVENTIONS

She underwent surgical decompression and hematoma removal 1 week later.

OUTCOMES

One week after operation, the sensory deficit above C6 level improved, but there was no improvement in her muscle strength and dyspnea. Unfortunately, she died 1 month later.

LESSONS

Our case highlights recurrent hemiparesis with complete spontaneous recovery mimicking TIA is a rare initial presentation of SSEH. It is important to perform careful clinical assessments and neuroimaging investigations for correct diagnosis. Neck pain and hemiparesis sparing cranial nerve are important signs for distinction of SSEH from acute ischemic cerebrovascular diseases.

Spontaneous Epidural Hematoma Associated with Venous Phlebolith in Cervical Spine and Possible Pathogenesis

Although the etiology of spontaneous spinal epidural hematoma (SSEH) is unclear, SSEH is known to be associated with anticoagulants, coagulopathy, vascular malformation, hypertension, and pregnancy. However, no report has been issued on the relation between SSEH and venous phlebolith. Here, the authors present an extremely rare case of SSEH associated with phlebolith in the cervical spine and suggest a possible pathogenesis. A 36-year-old man without any relevant medical history presented with neck pain and numbness and severe radiating pain on the left arm. Magnetic resonance imaging showed epidural hematoma at the C5–7 level, and computed tomography revealed a calcified nodule in the left epidural hemorrhage at C6 level. During left partial laminectomy, epidural venous plexus, and thick epidural hematoma were found, and hematoma removal revealed a white, ovoid, smooth, hard mass of diameter 3 mm. Histopathologic examination confirmed the mass as a venous phlebolith. The presence of a calcified solitary nodule in dorsal epidural space indicates the presence of phlebolith and the risk of SSEH. In such cases, the authors recommend spine surgeons should take into consideration the possibility of epidural hemorrhage.

Clinical Features, Management, and Prognostic Factors of Spontaneous Epidural Spinal Hematoma: Analysis of 24 Cases

BACKGROUND

Spontaneous spinal epidural hematoma (SSEH) is a rare neurosurgical emergency. It presents as acute spinal cord compression and usually requires surgical decompression. The patients who will benefit most from decompression surgery are unknown, and the factors associated with prognosis remain controversial. The purpose of our study was to identify the clinical features, treatments, and main factors related to the prognosis of SSEH.

METHODS

We reviewed the records of 24 patients treated for SSEH from September 2010 to January 2016 at West China Hospital. Clinical features, radiologic images, treatment methods, and clinical outcomes were reviewed retrospectively. To ascertain which factors were related to outcomes, statistical analysis was performed.

RESULTS

Among 24 patients, 19 presented with severe initial neurologic deficits (American Spinal Injury Association grade A-C) underwent decompressive surgery, and the remaining patients (initial American Spinal Injury Association grade D or E) received conservative treatment. Among the 19 patients in the operation group, seven (36.8%) had good outcomes, whereas 12 (63.2%) had poor outcomes. All patients in the conservative group had good outcomes.

CONCLUSIONS

SSEH is a rare but serious illness. It is more likely that SSEH arises from a ruptured internal vertebral venous plexus. The initial neurologic status is the determining factor influencing the treatment method and clinical outcome. The number of involved segments cannot be used to decide the treatment method or predict prognosis. Patients with shorter operative intervals appear to have better neurologic recovery.

Spontaneous spinal epidural hematoma: literature review

Review the current literature regarding spontaneous spinal epidural hematomas (SSEHs) and report on the known risk factors, evaluation, and treatment of this rare entity. A literature search was performed using PubMed and Ovid to identify articles pertaining to SSEHs. Due to the rarity of the pathologic entity, only scattered case reports and associated reviews are available. SSEHs are a rare yet potentially life-altering event. The underlying risk factors are poorly understood, and SSEHs present with minimal or no antecedent trauma. SSEHs warrant urgent surgical intervention given the associated risk of permanent neurologic sequelae. Given the potential for persistent neurologic deficits, physicians must entertain a clinical suspicion of SSEH when a patient presents with a history of back pain followed by neurologic deficits. Even without clear risk factors for hemorrhage, the appropriate evaluation to include advanced imaging studies should be obtained to allow for identification of this entity and urgent surgical management.

Spontaneous spinal epidural hematoma management: a case series and literature review

OBJECTIVE

Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord and leading to acute neurological deficits. Standard therapy is decompressive laminectomy, although spontaneous recoveries have been reported. Sub-optimal therapeutic principles contribute to SSEH's 5.7% mortality-which patient will benefit from surgery remains unclear. This study aims to investigate parameters that affect SSEH's progression, outlining a best-practice therapeutic approach.

MATERIALS AND METHODS

Literature review yielded 65 cases from 12 studies. Furthermore, 6 cases were presented from our institution. All data were analyzed under American Spinal Injury Association (ASIA) score guidelines.

RESULTS

Fifty percent of SSEH patients do not fully recover. In all, 30% of patients who presented with an ASIA score of A did not improve with surgery, although every SSEH patient who presented at C or D improved. Spontaneous recovery is rare-only 23% of patients were treated conservatively. Seventy-three percent of those made a full recovery, as opposed to the 48% improvement in patients managed surgically. Thirty-three percent of patients managed conservatively had an initial score of A or B, all improving to a score of D or E without surgery. Regardless, conservative management tends toward low-risk presentations. Patients managed conservatively were three times as likely to have an initial score of D than their surgically managed counterparts.

DISCUSSION

The degree of pre-operative neural deficit is a major prognostic factor. Conservative management has proven effective, although feasible only if spontaneous recovery is manifested. Decompressive laminectomy should continue to remain readily available, given the inverse correlation between operative interval and recovery.

Ultra-delayed lumbar surgical wound hematoma

Background:

There exists an inherent risk of increased venous thromboembolism (VTE) in surgical spine patients, which is independent of their existing risk factors. Prophylaxis and treatment of VTE is an imprecise practice and may have serious complications even well after the initial surgery. Furthermore, there are no clear guidelines on how to manage postoperative spine patients with regards to the timing of anticoagulation.

Case Description:

Here, we present the case of a middle-aged male, status post L2/3 laminectomy and discectomy who developed bilateral below the knee deep venous thrombosis. He was started on Enoxaparin and transitioned to Warfarin and returned with axial back pain, and was found to have a postoperative hematoma almost 3 weeks later in a delayed fashion.

Conclusion:

Delayed surgical wound hematoma with neural compression is an important complication to identify and should remain high on the differential diagnosis in patients on warfarin who present with axial spinal pain.

Spontaneous Spinal Epidural Hematoma: A Study of 55 Cases Focused on the Etiology and Treatment Strategy

BACKGROUND

Spontaneous spinal epidural hematoma (SSEH) is a rare neurologic emergency of the spinal cord. Its cause and treatment strategy remain controversial. This study aimed to evaluate a significant cause of SSEH and to discuss the treatment strategy according to the clinical outcomes of patients in 2 institutions.

METHODS

Fifty-five cases of SSEH treated at our institutions between February 2002 and February 2016 were retrospectively analyzed.

RESULTS

The mean age of the first SSEH onset was 31.8 years. The follow-up rate was 72.7%, with 28 patients (70%) showing satisfactory clinical outcomes. Forty patients received preoperative spinal digital subtraction angiography. Spinal epidural (extradural) arteriovenous fistula was detected in 6 patients (15%), 5 of whom showed 1 type of special slow-flow shunt. Nineteen patients (34.5%) suffered from multiple episodes until they underwent invasive treatments or last follow-up. Rebleeding was confirmed in 8 patients. None of the patients had a subsequent episode or rebleeding after invasive treatment. The risk factors for poor clinical outcome included advanced age at initial onset (P = 0.020), a short progression interval (P = 0.030), no symptom relief after admission (P = 0.011), hypesthesia (P = 0.017), complete spinal cord injury (P = 0.001), and hematoma below the T4 level (P = 0.014).

CONCLUSIONS

Spinal epidural (extradural) arteriovenous fistula is a significant cause of SSEH. Standard spinal digital subtraction angiography is necessary for patients with SSEH. Conservative treatment could not prevent occurrence of multiple episodes or rebleeding in patients. Microsurgery should be recommended as the preferred treatment strategy for SSEH. Endovascular embolization is also recommended if applicable.

Large, spontaneous spinal subdural-epidural hematoma after epidural anesthesia for caesarean section: Conservative management with excellent outcome

Background:

Iatrogenic or spontaneous spinal hematomas are rarely seen and present with multiple symptoms that can be difficult to localize. Most spontaneous spinal hematomas are multifactorial, and the pathophysiology is varied. Here, we present a case of a scattered, multicomponent, combined subdural and epidural spinal hematoma that was managed conservatively.

Case Description:

A 38-year-old woman came to the emergency department (ED) complaining of severe neck and back pain. She had undergone a caesarean section under epidural anesthesia 4 days prior to her arrival in the ED. She was placed on heparin and then warfarin to treat a pulmonary embolism that was diagnosed immediately postpartum. Her neurological examination at presentation demonstrated solely the existence of clonus in the lower extremities and localized cervical and low thoracic pain. In the ED, the patient's international normalized ratio was only mildly elevated. Spinal magnetic resonance imaging revealed a large thoracolumbar subdural hematoma with some epidural components in the upper thoracic spine levels. Spinal cord edema was also noted at the T6-T7 vertebral level. The patient was admitted to the neurosurgical intensive care unit for close surveillance and reversal of her coagulopathy. She was treated conservatively with pain medication, fresh frozen plasma, and vitamin K. She was discharged off of warfarin without any neurological deficit.

Conclusions:

Conservative management of spinal hematomas secondary to induced coagulopathies can be effective. This case suggests that, in the face of neuroimaging findings of significant edema and epidural blood, the clinical examination should dictate the management, especially in such complicated patients.
