摘　　要：目的探讨脑动静脉畸形(BAVM)出血的危险因素。方法收集DSA确诊的BAVM患者105例,分析BAVM出血的危险因素。结果单因素分析表明,BAVM破裂出血的危险因素有病灶位置、大小,供血动脉类型、数目,引流静脉类型、数目、形态及是否合并动静脉瘘;多因素Logistic分析发现,病灶位置、大小,供血动脉类型、数目,引流静脉数目及是否合并动静脉瘘是出血的危险因素,而引流静脉扩张可能是保护因素。结论病灶位于幕下或大脑深部、畸形团<3cm、单支静脉引流、单纯穿支动脉供血及多支供血动脉、合并动静脉瘘是BAVM出血的危险因素。Objective To analyze risk factors of hemorrhagic brain arteriovenous malformation （BAVM）.Methods Totally 105 BAVM patients confirmed with DSA were collected, and corresponding risk factors were analyzed.Results Univariate analysis suggested that factors were correlated to hemorrhagic presentation including the site and size of the lesions, the type and number of feeding arteries, the number, type and form of draining veins and co-existing arteriovenous fistula. Multiple factors Logistic analysis showed that the location, size, the type and amount of supplying arteries, the number of the draining vein and combined with arteriovenous fistula were the risk factors for hemorrhagic presentation, and drainage vein dilation might be a protective factor.Conclusion Infratentorial and deep cerebral lesions, arteriovenous malformation with diameter 〈3 cm, single draining vein, pure perforating artery, multiple feeding arteries and combined with arteriovenous fistula are risk factors for hemorrhagic BAVM.
