颅内深部小型动静脉畸形的血管内介入治疗

目的探讨颅内深部小型动静脉畸形血管内介入治疗的安全性及临床效果。方法回顾分析12例颅内深部小型动静脉畸形患者采用血管内介入治疗的临床资料，其中畸形位于基底节区6例，丘脑．基底节区4例，小脑上蚓部2例；采用Onyx或NBCA进行栓塞治疗。结果完全栓塞7例（58．3％），次全栓塞3例（25％），部分栓塞2例（16．7％），残余畸形者行伽玛刀治疗，随访3个月至2年，平均12个月，无严重并发症及死亡病例。结论颅内深部小型动静脉畸形根据具体情况采用血管内介入栓塞，能收到满意的效果，但栓塞率和畸形血管构筑、供血动脉多少以及血管条件相关。

Embolization of small deep intracranial arteriovenous mafformation

Objective To explore the safety and efficiency of interventional embolization of small deep intracranial arteriovenous malformation. Methods Twelve cases with small deep intracranial arteriovenous malformation were treated by interventional embolization with Onyx or NBCA. Among them, 6 located at basal ganglion, 4 at thalamus and basal ganglion area and 2 in upper cerebellum. Results Total obliteration was achieved in 7 cases（58.3%）, subtotal obliteration was achieved in 3 patients（25%） and other 2 cases were obliterated partially. For patients with residual deformity, gamma knife was performed. There were no severe complications and death in our series. Conclusion Interventional embolization is an accessible treatment for small deep intracranial arteriovenous malformation, the rate of embolization depends on the architecture of the malformation, number and condition of feeding artery.
