OBJECTIVES
To compare the outcome of autogenous arteriovenous fistulas (AVF) with interposition graft fistulas for hemodialysis access.
DESIGN
Retrospective clinical study.
SETTING
Department of Surgery, Zurich University Hospital.
METHODS
Primary and secondary patency rates were calculated by life tables. Factors potentially affecting patency were studied by comparison of life tables using the log rank test.
MAIN RESULTS
From 1980 to 1992, 414 patients were operated on for long-term vascular access. 720 fistulas were created including 429 AVF and 291 interposition grafts (150 bovine xenografts, 69 PTFE grafts, 59 sheep collagen grafts, 10 autologous and 1 homologous vein grafts). Secondary patency rates after 1 and 3 yr were 74/64% in AVF, 56/24% in bovine xenografts, 58/40% in PTFE grafts and 71/45% in sheep collagen grafts. The latter performed not significantly worse than AVF. Primary and secondary patency rates were significantly lower in women.
目的
比较自体动静脉内瘘（AVF）与搭桥移植内瘘用于血液透析通路的效果。
设计
回顾性临床研究。
地点
苏黎世大学医院外科。
方法
通过寿命表计算初次通畅率和二次通畅率。使用对数秩检验比较寿命表，研究可能影响通畅率的因素。
主要结果
1980年至1992年，414例患者接受了长期血管通路手术。共创建了720个内瘘，其中包括429个AVF和291个搭桥移植内瘘（150个牛异种移植、69个聚四氟乙烯移植、59个羊胶原移植、10个自体静脉移植和1个同种异体静脉移植）。AVF术后1年和3年的二次通畅率分别为74%/64%，牛异种移植为56%/24%，聚四氟乙烯移植为58%/40%，羊胶原移植为71%/45%。羊胶原移植的效果不比AVF差很多。女性的初次和二次通畅率明显较低。
