脊髓血管畸形的栓塞治疗

Intravascular Embolization of Spinal Cord Arteriovenous Malformation

自1993年1月至1994年共栓塞治疗6例脊髓血管畸形患者,其中髓内 AVM 3例,1例位于颈段,2例位于胸段;1例为球型,2例为幼稚型;硬脊膜下髓周 AVF 3例均位于圆锥马尾部,其中(?)型1例,(?)型2例,6例中,5例完全闭塞,治疗后病情有不同程度改善;1例部分栓塞,症状无明显改善,无明显并发症发生.随访2～20个月,3例髓周 AVF 基本恢复正常,3例髓内 AVM,也均有不同程度好转.我们认为栓塞治疗对难以手术的髓内 AVM,(?)型和(?)型 AVF 不失为有效的治疗方法.

Six spinal cord AVMs underwent intravascular embolization in our hospital between January 1993 and August 1994 were reported.All cases diagnosed by selective digital substract angiography.There were one cervical two thoracic intramedullar AVMs,and three lumbodorsal intradural perimedullary AVFs,Five cases received complete occlusion and one intramedullary AVM was partially embolized.Three perimedullary AVFs recovered markedly and partial improvement was also seen in three intramedullary AVMs during the follow-up period from 2 to 20 months.We concluded that intravascular embolization therapy is an alternative and effective manner in treating intramedullary AVM and type Ⅱ type Ⅲ perimedullary AVF.
