Abstract： 目的通过对脑动静脉畸形(AVM)DSA造影特点与出血因素的研究,为判断出血的危险性及为临床选择治疗方案提供依据.方法对我院行血管内栓塞治疗脑AVM 80例(其中颅内出血49例)进行分析,了解脑AVM畸形团的大小、部位、供血动脉的类型、引流静脉数目及路径、AVM合并动脉瘤等因素与脑出血的关系.结果脑AVM中、小型畸形团出血危险性高于大型;脑深部基底节和后颅凹的AVM出血的危险性比大脑皮层的AVM大;脑穿支供血动脉和椎动脉供血的AVM出血危险性大;脑AVM引流静脉数越少出血的危险性越高,而引流静脉路径与出血无明显关系;脑AVM合并动脉瘤易出血.结论脑AVM出血与血管构筑因素有关,根据血管不同构筑因素,判断脑AVM出血的可能性,为血管内栓塞治疗提供指导.
