Spontaneous spinal hematoma (SSH) after low-molecular-weight heparin (LMWH) therapy is a rare cause of compressive myelopathy with neurological deficit. Emergent surgical decompression is commonly advocated for optimal neurological recovery. Only three cases of spontaneous spinal subdural hematomas after LMWH therapy have been reported in the literature, and this is the first report of a spontaneous cervical epidural hematoma (EDH).
To highlight the importance of conservative management in an unusual case of cervical EDH with neurological deficit after LMWH therapy.
Clinical case report.
A 65-year-old man presented with weakness of upper and lower limbs with bowel and bladder dysfunction after LMWH therapy for an acute coronary syndrome. Magnetic resonance imaging (MRI) revealed an anterior cervical EDH extending from C4 to T1 with significant cord compression. Associated comorbidities precluded emergent surgical intervention, and the patient was managed conservatively with cessation of LMWH therapy.
The patient showed signs of early neurological recovery within 24 hours (ASIA C [American Spinal Injury Association] to ASIA D) of cessation of LMWH, and hence surgery was deferred. Complete motor and sensory recovery was observed at 1-month follow up with resolution of the cervical EDH without any cord compression evident on the MRI.
LMWH therapy is an important cause of SSH leading to significant neurological deficits. Conservative management is a viable treatment option in patients who demonstrate early and sustained neurological recovery with the cessation of LMWH therapy.
低分子肝素(LMWH)治疗后自发性脊髓血肿(SSH)是一种罕见的压迫性脊髓病伴神经功能缺损的原因。紧急手术减压通常被认为是获得最佳神经恢复的方法。文献中仅报道了 3 例 LMWH 治疗后自发性脊髓硬膜下血肿的病例,而这是首例 LMWH 治疗后自发性颈硬膜外血肿(EDH)的报告。
强调在 LMWH 治疗后出现神经功能缺损的不寻常颈椎 EDH 患者中采用保守治疗的重要性。
临床病例报告。
一名 65 岁男性在因急性冠状动脉综合征接受 LMWH 治疗后出现四肢无力,伴有肠和膀胱功能障碍。磁共振成像(MRI)显示 C4 至 T1 段前颈椎 EDH,脊髓受压明显。由于存在相关合并症,不能进行紧急手术干预,因此患者停止 LMWH 治疗后采用保守治疗。
停止 LMWH 治疗后 24 小时内(美国脊髓损伤协会[ASIA] C 级至 D 级)患者出现早期神经恢复迹象,因此推迟了手术。在 1 个月的随访中观察到完全的运动和感觉恢复,颈椎 EDH 消失,MRI 未见脊髓受压。
LMWH 治疗是 SSH 的一个重要原因,导致明显的神经功能缺损。对于停止 LMWH 治疗后表现出早期和持续神经恢复的患者,保守治疗是一种可行的治疗选择。
