目的 探讨硬脑膜动静脉瘘 (DAVF)的发病机理。方法 (1)对照组 :10条犬 ,结扎并剪断右侧颈外静脉 ;(2 )实验 1组 :15条犬 ,吻合右侧颈外静脉远心端与颈总动脉近心端 ;(3)实验 2组 :15条犬 ,结扎并剪断左侧颈外静脉 ,然后与实验 1组做相同处理。结果 对照组无DAVF发生 ;实验 1组有 3条犬发生DAVF ;实验 2组有 1条犬发生DAVF。结论 单纯升高静脉窦内压力可以诱发DAVF。
Objective To investigate the pathogenesis of dural arteriovenous fistula (DAVF). Methods (1) Control group: 10 dogs were ligated and the right external jugular vein was ligated and cut; (2) Experimental group 1: 15 dogs, which were close to the telecentric end of the right external jugular vein and the common carotid artery; ) Experiment 2 group: 15 dogs, ligation and cutting the left external jugular vein, and then do the same with the experimental group 1 treatment. Results There was no DAVF in control group; DAVF in 3 dogs in experiment 1 group and DAVF in 1 dog in experiment group 2. Conclusion Increased sinus venous pressure can induce DAVF.
