摘要
本文采用血管造影检查对56例长期血透患者的动静脉内瘘进行了临床观察。结果表明静脉狭窄和静脉动脉瘤发生率最高,分别占并发症的44.8%,静脉狭窄以距瘘口5 cm之内最为常见,其狭窄程度与血流量密切相关。作者认为血管造影能直接显示有关血管的全景,对血管异常病变的诊断准确率高。目前,血管造影仍不失为一种方便可行的血管通路影像诊断最好的方法。
56 patients with hemodialysis arteriovenous fistulae were investigated by venous angiography.Venous stenosis and aneuryms were the most common complications in this study accounting for 44.8% of the complications.The degree of venous stenosis correlated well with blood flow.Our data suggested that early detection,localizition and characterizition of lesions by venous angiography are extremely important for arteriovenous access.
