Spontaneous spinal epidural haematoma: when magnetic resonance imaging is an unavoidable choice in an emergency department

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.

A Case of Spontaneous Spinal Epidural Haematoma in the Emergency Department Associated with Warfarin Therapy

Spontaneous spinal epidural haematoma (SSEH) is a neurosurgical emergency that requires early diagnosis and treatment. An 88-year-old man presented to the emergency department with complaints of weakness in the legs, walking deficit, incontinence and back pain for the last two days. He had been on warfarin therapy for 5 years for atrial fibrillation. There was no antecedent trauma. The neurological examination revealed hypoesthesia below the T6 level, anaesthesia below the T10 level and complete paraplegia of both lower extremities. The INR level was 7.81 on admission. Magnetic resonance imaging revealed a posterolateral epidural haematoma extending from T2 to L5. He was given fresh frozen plasma and vitamin K in the emergency department. Emergency thoracic and lumbar laminectomy was performed by neurosurgeons. The probability of SSEH should be investigated in any patient under anticoagulation therapy who presents with signs of spinal compression in the emergency department.
