脑动静脉畸形(AVM)是一堆结构变异的动脉和静脉交错缠绕在一起的血管团块,动静脉之间形成一至数个瘘道而无毛细血管,血液可由动脉通过动静脉瘘直人静脉,再回流到静脉窦,这种异常的脑血管结构和脑血流改变可导致脑出血、脑盗血等而引起一系列脑功能障碍,因此必须进行积极治疗[1] Cerebral arteriovenous malformation (AVM) is a pile of structural variation of blood vessels and staggered intertwined blood vessels, the formation of arterioventilation between several fistula without capillaries, the blood can be arterial arteriovenous fistula straight vein, And then back to the sinus, this abnormal cerebrovascular structure and changes in cerebral blood flow can lead to cerebral hemorrhage, cerebral steal caused a series of brain dysfunction, it must be actively treated [1]
