脑动静脉畸形的血管内栓塞治疗

Intravascular embolization treatment of cerebral arterio-venous malformation

目的 :探讨脑动静脉畸形 (AVM)血管内栓塞治疗的疗效。方法 :2 0例脑AVM患者 ,行数字减影全脑血管造影 (DSA)后 ,采用Magic - 1 8F ,1,5F或MP 1 2F微导管系与α -氰基丙烯酸正丁酯 (NBCA)栓塞剂 ,进行血管内栓塞治疗 ,其中 6例栓塞后行γ -刀治疗。结果 :全部病人手术过程顺利 ,疗效满意。栓塞达 70 %以上 8例 ,70 %以下 12例。 1例发生短暂的血管痉挛 ,无出血等并发症和死亡发生。术后随访 ,全组临床症状均明显改善。结论 :血管内栓塞治疗脑AVM可提高治愈率 ,降低并发症和病死率 。

Aim: To evaluate the effect of intravascular embolization treatment of cerebral arterio-venous malformations(AVMs). Methods: Twenty cases with cerebral arterio-venous malformation(AVM) were analysed. All underwent digital subtract angiography (DSA) before the treatment , then the embolizations were performed with the using of Magic-1.8 F,1,5 F or MP 1.2 F micro cathete system and NBCA(n-butylcyanoacrylate). Six cases were treated with gamma knife later. Results: 70% occlusion of AVM were obtained in 8 cases, and less than 70% occulsion in 12 cases. Except for one case of temporarily vasospasm, no serious complication occurred. The follow-up observation showed that the clinical symptoms were significant improved in all cases. Conclusion: Intravascular embolization treatment is a safe and effective method of cerebral arterio-venous malformation(AVM).
