血液透析是尿毒症患者维持生命的重要治疗手段。现阶段血液净化技术不断发展,透析质量不断提高,长期维持性血液透析(MHD)患者的生存时间明显延长。良好的血管通路是MHD患者接受血液透析治疗顺利进行的首要条件,是患者的生命线。美国2006年发布的DOQI指南指出:自体动静脉内瘘是血液透析的首选血管通路。临床常选用的血管为前臂腕部桡动脉—头静脉内瘘,其次为腕部尺动脉—贵要静脉内瘘、 Hemodialysis is an important treatment for patients with uremia to sustain life. At this stage of blood purification technology continues to develop, the quality of dialysis continues to improve, long-term maintenance hemodialysis (MHD) patients significantly longer survival time. Good vascular access is the first condition for successful MHD patients to undergo hemodialysis and is the lifeline for patients. DOQI guidelines issued by the United States in 2006 pointed out: Autologous arteriovenous fistula is the preferred vascular access for hemodialysis. Clinically, the commonly used blood vessels for the forearm wrist radial artery - head fistula, followed by the wrist ulnar artery - expensive intravenous fistula,
