Endovascular treatment of spinal vascualar malformation

目的 探讨经血管内治疗脊髓动静脉畸形 (AVM)的方法。方法 本组 4 1例脊髓AVM。3例用 3个 0真丝线段栓塞 ,14例采用干燥硬脑膜栓塞 ,16例采用PVA栓塞 ,8例采用α 氰基丙烯酸正丁酯 (NBCA)胶粘合剂经微导管超选择性栓塞。结果 病灶完全栓塞 2 7例 ,部分栓塞 14例 ,肢体瘫痪症状改善 36例 ,其中 5例症状未改善。平均随访 32个月 ,有 18例症状完全恢复正常 ,5例复发 ,无再出血发生。

Objective To evaluate the treatment of spinal cord vascular malformations by endo vascular therapy. Methods All 41 patients including 3 cases were embolized by 3 0 silk line segments, 14 cases by selective embolization of dry dura particles, 16 by PVA and 8 cases by NBCA. Results Lesions were completely embolized in 27 cases, and partialy embolized in 14 cases. Paralysis of limbs were significantly improved in 36 cases, the other 5 cases showed no improvement on account of previous resection of the lesions. During 32 months follow up period, 18 cases recovered completely but with recurrence in 5. Conclusion Endovascular therapy is effective for spinal cord vascular malformations.
