RESUMO
Hemodialysis that to maintain life quality and may be preliminary stage of kidney transplantation is essential in end-stage renal disease(Esrd) patients. Since 1996, Brescia-cimino are used to internal radio- cephalic fistula and this fistula method was the most popular in world-wide. And then variable methods (e.g, Autogenous, PTFE, Dacron etc.) were usually tried instead of above standard fistula. We experienced 75 fistulas in 62 cases from Jan. 1993 to Dec. 1996 and among 75 fistula operations standard radio-cephalic fistula was 56, brachio-cephalic fistula 10, graft fistula 9. Early patency failure rate of A-V fistula was 9 cases, 14.5%. Significant factors to effect in patency of A-V fistula were propably diabetic mellitus, venous diameter, graft material and were not related to age/sex, blood pressure, BUN/creatinine etc. In conclusion the reduction of early patency failure rate in A-V fistula is to maintain long patency rate of A-V fistula
