血管内栓塞治疗脑动静脉畸形

目的:探讨血管内栓塞治疗脑动静脉畸形(cAVM)的临床意义。方法:应用血管内栓塞治疗cAVM 23例,栓塞剂为NBCA或Onyx,栓塞后2例行显微手术治疗,4例行咖玛刀治疗。结果:畸形血管团完全消失5例,消失80%以上6例,60%~80%7例,60%以下5例。栓塞后1例发生脑出血。结论:血管内栓塞治疗cAVM的方法是安全的,可治愈部分cAVM,对于大型、重要功能区的cAVM,血管内栓塞联合手术或放疗可提高治愈率,降低致残率和病死率。

Endovascular embolization in cerebral arteriovenous malformation

Objective:To explore the efficacy of endovascular embolization in treatment of cerebral arteriovenous malformation(cAVM).Methods:23 patients received endovascular embolization with NBCA or ONYX as embolic materials,among which 2 cases were referred to undergo microsurgery therapy and 4,by gamma knife procedure.Results:The endovascular embolization resulted in anatomical cure in 5 cases,more than 80% disappearance of the malformations in size in 6,60% to 80% in 7 and less than 60% in 5.Only 1 case complicated with hemorrhage after the procedure.Conclusion:Endovascular embolization is a safe an d reliable method for treating AVM,but to some larger AVMs or ones situated at the crucial functional position,endovascular embolization combined with surgery or gamma knife should be more effective,which can greatly reduce the complications and even mortality.
