目的 比较不同的手术方式对动静脉内瘘(AVF)在使用过程中血流量的差异，探寻适宜于肾衰竭患者较佳的手术方式。方法 采用彩色多普勒超声检查测定血液透析患者以不同手术方式形成的动静脉内瘘的血流量大小。结果 43例端侧吻合并加用钛环固定的患者造瘘后1个月时内瘘血流量在(592±116)ml/min。其内瘘的血流量调节在较理想的范围内，透析间期均无心力衰竭发作而透析时血流量可达到300ml/min。结论 用丝线缝合将桡动脉与头静脉行侧-端吻合并加用3.0mm钛环固定吻合口大小是慢性肾功能衰竭患者行动静脉内瘘(AVF)的最佳手术方式。既不诱导高心输出性心力衰竭的发生，而透析时血流量又可达到所需要的理想水平。

Objective To compare the difference of blood-flow of A-V fistula by various surgical procedure, and find the best surgical procedure. Methods The blood flow of A-V fistula in various surgical procedure were determine by color doppler ultrasonic. Results The blood flow of A-V fistula of 43 patients whose fistula were anastomosed by end-to-side style and titaniumring was (592±116)ml/min in average. There was no heart failure occured interdialysis and blood flow could maintain 300ml/min during dialysis. Conclusion The A-V fistula, sewed up with suture in end-side anastomoses and fixed anastomoses by 3.0mm titanium ring, is the best surgical procedure. It does not result in heart-failure and it could maintain sufficient blood flow.
