血液透析患者内瘘闭塞因素的探讨

Factors Associated with Arteriovenous Fistula Occlusion in Hemodialysis

目的 :探讨动静脉内瘘闭塞的因素。方法 :收集我院开展血液透析以来 11例内瘘闭塞患者的临床资料 ,进行回顾分析。结果 :发现动静脉管径、平均动脉压以及尿毒症的原发病与内瘘的闭塞有关。结论 :低血压、静脉管径细以及糖尿病、血管炎等周围血管病变的患者内瘘易发生闭塞 ;吻合口口径在 8～ 10 mm较适宜 ;内瘘的使用尽量在

Objective:To research the factors associated with arteriovenous fistula occlusion.Methods:Clinical data of 11 patients with arteriovenous fistula occlusion in our hospital were retrospectively analysed.Results:Diameter of artery and vein,mean arterial pressure(MAP) and essential diseases of uremia patients had correlation with fistula occlusion.Conclusion:Patients with hypotension and small vein and diabetes mellitus and vasculitis easily suffered fistula occlusion;In end side AV fistula the anastomosis size should be 8～10 mm;The fistula should not be punctured until the 6th week.
