经血管内栓塞治疗脊髓动静脉畸形

Endovascular Embolization Treatment of Spinal Arteriovenous Malformations

目的 探讨经血管内栓塞治疗脊髓血管畸形的可行性。方法 采用微导管注入真丝线段、Ivalon混合剂栓塞。结果88例中84例病变完全消失,4例栓塞60％～70％。症状明显改善81例,其中5例栓塞后肌力由Ⅰ～Ⅱ级恢复到Ⅳ级。7例入院时肌力0级,栓塞后无明显改善。结论 经血管内栓塞治疗脊髓血管畸形,是行之有效的一种新方法。

Objective To evaluate the therapeutic efficacy of endovascular embolization on the spinal arteriovenous malformations (SAVMs). Method Data of 88 cases with SAVMs who received the endovascular embolization with the silk suture combined with Ivalon or NBCA, were reviewed retrospectively. Results Complete obliteration of the AVMs were achieved in 84 of the 88 cases with SAVMs. Partial obliteration (60%~70%) of the AVM was obtained in 4 cases. The marked symptomatic improvement was experienced in 81 cases, of whom, 5 had improvement of myodynamia (from grade I or II to grade IV) after the embolization. The symptoms were unchanged in 7 cases. Conclusion The endovascular embolization is an effective and safe option for treatment of the SAVMs.
