腰椎术后硬膜外血肿导致马尾神经功能损害回顾性分析

目的：观察腰椎术后出现硬膜外血肿形成致马尾神经功能损害的原因、治疗及预防措施。方法分析我院2006年1月—2014年1月腰椎术后并经腰椎磁共振证实硬膜外血肿形成致马尾神经功能损害11例的诊治资料，结合资料分析其形成原因、临床表现、诊断方法、手术时机和预后。结果11例患者均行二次椎管探查、止血和血肿清除术，术后随访时间平均为15个月（6个月~36个月），部分患者的神经功能有一定程度恢复。结论硬膜外血肿形成致马尾神经功能损害是脊柱外科术后严重的并发症，术中确切止血，保证术后引流管通畅，严密观察神经功能变化，及时手术探查及血肿清除是预防和治疗的有效措施。
