一、概述脑动静脉畸形是中枢神经系统的一种先天性、非肿瘤性血管异常,自Luschka(1854)首次报告以来已有百余年,但迄今对其治疗仍存在未解决的问题。脑动静脉畸形在蛛网膜下腔出血原因中占6%,在经证实的颅内肿瘤中占1.5～4%,脑动静脉畸形与颅内动脉瘤的比率为1:6.5。脑动静脉畸形发自胚胎早期原始动静脉沟通变异的残余,在正常发育情况下动静脉之通变间由毛细血管网隔开。动静脉畸形中包括扩大的供血动脉和引流静脉,其间为成
I. Overview Cerebral arteriovenous malformations are a congenital and non-tumorous vascular abnormalities of the central nervous system. More than a hundred years have passed since Luschka (1854) first reported. However, there are still unanswered questions about their treatment so far. Cerebral arteriovenous malformations accounted for 6% of the causes of subarachnoid hemorrhage, 1.5-4% of confirmed intracranial tumors, and the ratio of cerebral arteriovenous malformations to intracranial aneurysms was 1: 6.5. Cerebral arteriovenous malformations originate from remnants of early embryo arteriovenous communication variability and are separated by capillary networks during normal development. Arteriovenous malformations include an enlarged feeding artery and drainage veins, during which time
