Dural arteriovenous fistulas (DAVFs) are abnormal vascular connections located within the dura mater which are thought to be promoted by venous hypertension and venous sinus thrombosis. The symptoms associated with DAVFs depend on the direction and adequacy of venous drainage pathways, the amount of arteriovenous shunting and specific location of the fistula. Our experience over a period of eight years with 268 patients suffering from cranial DAVFs in the transverse, sigmoid, superior sagittal, ethmoidal, inferior and superior petrosal, cavernous, and marginal sinuses are presented. The clinical presentation, radiographic evaluation, and treatment modalities for DAVFs in each of these locations are summarized.
硬脑膜动静脉瘘（DAVFs）是位于硬脑膜内的异常血管连接，被认为是由静脉高压和静脉窦血栓形成所促发。与硬脑膜动静脉瘘相关的症状取决于静脉引流途径的方向和通畅程度、动静脉分流的量以及瘘的具体位置。本文介绍了我们在八年时间里对268例患有横窦、乙状窦、上矢状窦、筛窦、岩上窦和岩下窦、海绵窦及边缘窦硬脑膜动静脉瘘患者的治疗经验。总结了这些部位硬脑膜动静脉瘘的临床表现、影像学评估及治疗方式。
