摘要目的 探讨彩色多普勒超声检测老年人长期血液透析动静脉内瘘并发症的临床应用价值.方法 36例血液透析老年患者,其中27例采用自体动静脉瘘,9例因自身血管条件限制,不能建立理想的血管通路,采用人工血管移植建立动静脉瘘,应用彩色多普勒超声检测动静脉内瘘的功能及其并发症的发生情况.结果 36例老年血液透析患者中,26例(72.2%)动静脉内瘘通畅,其中27例自体动静脉瘘患者中,6例(22.2%)出现并发症,9例人造血管内瘘患者中,4例(44.4%)出现并发症.结论 超声可清晰显示动静脉内瘘处移植自体血管或人工血管的位置、走行、管腔及其血流动力学情况,及时发现并发症,为临床采取措施提供参考依据.

abstractsObjective To evaluate the clinical application of color Doppler ultrasound in monitoring the complications of arterialvenous fistula in elderly patients. Methods The 36 hemodialysis patients over the age of 60 were enrolled, including 27 cases of autologous arteriovenous fistula and 9 cases of artificial vascular graft arteriovenous fistula. The ideal vascular access could not be established in the 9 cases due to their own conditions. Color Doppler ultrasonography was used to test the function of arteriovenous fistula and to observe its complications. Results The arteriovenous fistula in 26 cases (72.2 %) was patent in 36 elderly hemodialysis patients. The 6 cases (22.2 % ) in 27 of autogenous arteriovenous fistula and 4 cases (44.4 % ) in 9 of artificial arteriovenous fistula had complications. Conclusions Ultrasound can clearly show the position, pathway, lumen and blood flow dynamics of the transplanted autologous or artificial blood vessels in arteriovenous fistula so as to evaluate the effects of blood dialysis in elderly patients and to detect the complications for clinical reference.
