尸体动脉建立动静脉内瘘术

Cadaver arterial allograft for hemodialysis arteriovenous fistulas

目的 动静脉内瘘是慢性肾功能衰竭血液透析患者的重要“生命线”,但一些长期透析患者,由于多次手术及反复穿刺,上肢前臂已无可供做内瘘吻合的动静脉。我们采用尸体动脉作为移植血管制作动静脉内瘘。方法 将尸体动脉用乙醚及无水乙醇处理,保存于75％乙醇内。将尸体动脉作为移植血管制作动静脉内瘘3例。结果 术后血流通畅,血流量200-275ml·min-1。结论 用尸体动脉作为移植血管制作动静脉内瘘效果满意。

AIM Arteriovenous fistulas are very important for hemodialysis patients with chronic renal failure,But some patients'arms haven't any normal blood vessels for vascular access. We introduce cadaver arterial allograft for hemodialysis vascular access. METHODS Cadaver arterials are processed with ether and pure alcohol,then preserve cadaver arterials in 75% alcohol. They were used as hemodialysis vascular access in 3 cases. RESULTS Blood flow reach 200-275ml·min-1 and unobstruct. CONCLUSION Cadaver arterial allograft for hemodialysis vascular access are satisfying.
