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.
