Spontaneous Spinal Epidural Hematoma: A Case Report and Literature Review

Spontaneous spinal hematomas: A case series

PURPOSE

Spontaneous spinal hematoma (SSH), a rare neurological disorder, demands immediate diagnostic evaluation and intervention to prevent lasting deficits. This case series analyzes instances, particularly highlighting cases where vascular causes were identified despite inconclusive initial imaging.

METHODS

In a retrospective study of 20 patients treated for SSH at a Level I spine center from 01/01/2017 to 11/15/2023, we examined demographics, clinical presentation, imaging, and treatment details. Excluding traumatic cases, we present 4 instances of SSH associated with diverse vascular pathologies.

RESULTS

Patient ages ranged from 39 to 85 years, with a median age of 66 years. 45% were male, and 55% were female. Among 20 cases, 14 were epidural hematomas, 4 subdural, 1 combined epidural and subdural, and 1 subarachnoid hemorrhage. 85% presented with neurological deficits, while 3 solely had pain-related symptoms. 55% were under anticoagulant medication, and vascular anomalies were found in 25% of cases. The cause of SSH remained unclear in 20% of cases. MRI was performed for all patients, and DSA was conducted in 25% of cases. The 4 highlighted cases involved individuals with distinct vascular pathologies managed surgically.

CONCLUSION

Urgent attention is crucial for SSH due to possible lasting neurological consequences. The study emphasizes comprehensive diagnostics and surgical exploration, especially in cases with unclear etiology, to identify and address vascular causes, preventing hematoma progression or recurrence. Despite their rarity, vascular malformations contributing to spinal hematomas warrant particular attention.

Prognostic factors and surgical outcomes of spontaneous spinal epidural haematoma: a systematic review and meta-analysis

Spontaneous spinal epidural haematoma (SSEH) is a rare disease defined as blood accumulation within the vertebral epidural space without a cause identified, which can lead to severe neurological deficits. We aim to provide a comprehensive understanding of the prognostic factors affecting surgical outcomes in true SSEH and propose a critical time frame for operative management. A systematic literature search was performed and registered, using OVID Medline and EMBASE, in line with the PRISMA guidelines. Relevant demographic, clinical, surgical, and outcome data were extracted. The ASIA scale was uniformly used throughout our systematic review. Statistical analysis was performed via logistic regression. Of the 1179 articles examined, we included 181 studies involving 295 adult patients surgically treated for SSEH. SSEH were most commonly found in the cervicothoracic spine, with 2-4 spinal segments most commonly involved. Multivariable logistic regression model showed that the following factors were statistically significant in the post-operative outcome: operation type (P = 0.024), pre-operative neurologic status (P < 0.001), use of warfarin (P = 0.039), and operative interval (P = 0.006). Our retrospective analysis confirms the reversibility of severe neurological deficits after surgical intervention, with a prognosis of post-operative outcomes determined by the use of warfarin, pre-operative ASIA grade, and above all surgical evacuation within 12 h.

Neuroimaging and radiation exposure in pregnancy

Physiologic changes occurring in pregnancy and postpartum can have secondary effects on the maternal nervous system. While most alterations to neurologic function during pregnancy are transient, there is an elevated risk for more serious complication in the peripartum period, such as cerebrovascular events or exacerbation of preexisting neurologic conditions. Due to the morbidity and mortality associated with these neurologic manifestations in some cases, timely diagnostic evaluation is essential. In the pregnant population, the use of diagnostic techniques such as computed tomography (CT) and magnetic resonance imaging (MRI), commonly employed to evaluate emergent neurologic abnormalities, requires special consideration of the potential risks associated with prenatal exposure. This review discusses several neurologic conditions affecting women during pregnancy for which diagnostic imaging may be warranted. Concerns relating to CT and MRI procedures, radiation exposure in utero, and exposure to intravenous contrast by placental transfer and breastfeeding are also reviewed.

Nonsurgical Intervention in a Preeclamptic Patient with Spontaneous Spinal Epidural Hematoma

Background

Spontaneous epidural hematoma (SEH) is a rare finding in pregnancy, especially since most pregnant women do not have risk factors for developing SEH. The presence of epidural anesthesia can delay the diagnosis of SEH in pregnant patients. Immediate surgical decompression is the current standard of care for treating SEH.

Case Presentation

We present the case of a 37-year-old pregnant woman with preeclampsia with severe features who developed neurological deficits that were initially attributed to her epidural anesthesia. She was eventually found to have SEH with spinal stenosis at T5-T6 on MRI. Oral antihypertensives were used to keep the patient's blood pressures within normal limits, and she subsequently had complete resolution of her neurological symptoms and her SEH on imaging.

Conclusion

Preeclampsia may contribute to the development of SEH in pregnancy, and strict blood pressure control may potentially provide a safe and effective alternative to neurosurgery for these patients.

Acute Cervical and Thoracic Ventral Side Spontaneous Spinal Epidural Hematoma Causing High Paraplegia: A Case Report

Introduction

Spontaneous spinal epidural hematoma (SSEH) is a rare condition that can potentially cause paraplegia. SSEH has an increasing incidence rate and its cause remains unclear. Magnetic resonance imaging (MRI) results shows that SSEH presents a spinal epidural space-occupying lesion; therefore, emergency surgical treatment is required in some cases. MRI results of most SSEH cases showed that hematoma occurs in the dorsal or lateral side. By contrast, hematoma in the ventral side is very rarely shown.

Case Presentation

A 42-year-old healthy woman developed a sudden onset of severe neck pain with mild limb weakness, gradual breathing difficulty, and high paraplegia. MRI results revealed that an SSEH was compressing her spinal cord in the ventral epidural space from C2 to T3. Upon admission, she received emergency decompressive laminectomy in a posterior approach from C3 to T1, and the epidural hematoma was evacuated through full incision of the dorsal side dural, release of cerebrospinal fluid, and intermittent incision of the ventral side dural. The symptoms of limb paralysis and breathing distress gradually improved after recover rehabilitation, and the patient was discharged with life self-care after 2 months.

Conclusions

Performing early decompressive laminectomy and evacuation of hematoma on severe SSEH patients improves neurological outcomes. For patients with ventral side SSEH, the cerebrospinal fluid should be released after the incision on the dorsal side dural, and the ventral side dural should be gradually as well as intermittently clipped to evacuate the hematoma. The patient would also receive a good prognosis after the total release of the spinal cord compression.

Spontaneous spinal epidural hematomas: One case report and rehabilitation outcome

RATIONALE

Spontaneous spinal epidural hematoma (SSEH) is a relatively rare but potentially disabling disease, and the classical presentation of it includes an acute onset of severe, sometimes radiating back or neck pain, followed by signs and symptoms of rapidly evolving nerve root or spinal cord compression.

PATIENT CONCERNS

Here, we report a 26-year-old female patient presented with weakness in bilateral lower extremities, progressing to intense paraplegia and anesthesia without recent medical history of trauma, infection, surgery, or drug use.

DIAGNOSIS

A magnetic resonance imaging (MRI) scan of spinal cord was planned and a posterior epidural hematoma of the thoracic spine was observed.

INTERVENTIONS

A posterior decompression and hematoma evacuation was performed after diagnosis immediately. Early rehabilitation program of the specific kind spinal cord injury was formulated and implemented.

OUTCOMES

The patient finally can handle basic living activities, such as completing wheelchair locomotion, transferring from bed to wheelchair independently after 3 months of rehabilitation.

LESSONS

SSEH is a rarely occurring case in emergency. Acute chest pain and paraplegia could be the initial presentation of acute spinal epidural hemorrhage, but the diagnosis of patient without classical manifestations is still a challenge for doctors. Early diagnosis, prompt decompression, and individualized rehabilitation program can improve the prognosis and outcome.

[Warfarin-associated epidural hematoma with spinal cord compression]

Hemorrhages into the structures of the central nervous system are the most life threatening among warfarin-associated complications. There are extremely few reports about spontaneous spinal epidural hematomas (SEH) associated with warfarin, methods of their timely diagnosis, treatment approaches. The authors present the first in the domestic literature case-report of warfarin-associated spontaneous SEH and the literature review.

Clinical Outcomes of Spontaneous Spinal Epidural Hematoma : A Comparative Study between Conservative and Surgical Treatment

Objective

The incidence of spontaneous spinal epidural hematoma (SSEH) is rare. Patients with SSEH, however, present disabling neurologic deficits. Clinical outcomes are variable among patients. To evaluate the adequate treatment method according to initial patients' neurological status and clinical outcome with comparison of variables affecting the clinical outcome.

Methods

We included 15 patients suffered from SSEH. Patients were divided into two groups by treatment method. Initial neurological status and clinical outcomes were assessed by the American Spinal Injury Association (ASIA) impairment scale. Also sagittal hematoma location and length of involved segment was analyzed with magnetic resonance images. Other factors such as age, sex, premorbid medication and duration of hospital stay were reviewed with medical records. Nonparametric statistical analysis and subgroup analysis were performed to overcome small sample size.

Results

Among fifteen patients, ten patients underwent decompressive surgery, and remaining five were treated with conservative therapy. Patients showed no different initial neurologic status between treatment groups. Initial neurologic status was strongly associated with neurological recovery (p=0.030). Factors that did not seem to affect clinical outcomes included : age, sex, length of the involved spinal segment, sagittal location of hematoma, premorbid medication of antiplatelets or anticoagulants, and treatment methods.

Conclusion

For the management of SSEH, early decompressive surgery is usually recommended. However, conservative management can also be feasible in selective patients who present neurologic status as ASIA scale E or in whom early recovery of function has initiated with ASIA scale C or D.

Recent advances in epidural analgesia

Neuraxial anesthesia is a term that denotes all forms of central blocks, involving the spinal, epidural, and caudal spaces. Epidural anesthesia is a versatile technique widely used in anesthetic practice. Its potential to decrease postoperative morbidity and mortality has been demonstrated by numerous studies. To maximize its perioperative benefits while minimizing potential adverse outcomes, the knowledge of factors affecting successful block placement is essential. This paper will provide an overview of the pertinent anatomical, pharmacological, immunological, and technical aspects of epidural anesthesia in both adult and pediatric populations and will discuss the recent advances, the related rare but potentially devastating complications, and the current recommendations for the use of anticoagulants in the setting of neuraxial block placement.
