彩超监测24例尿毒症患者动静脉内瘘的回顾性研究

Retrospective study of vascular access by color Doppler ultrasonography in uraemic patients with internal arteriovenous fistula

目的监测尿毒症患者动静脉内瘘（AVF）术后1年血管通道的变化情况。方法24例尿毒症患者，AVF术后2周及1年分别行彩色多普勒超声检查，测量头静脉内径、桡动脉内径及内中膜厚度、瘘口直径、内瘘流量。结果AVF术后1年与术后2周比较：头静脉内径明显增宽，瘘口直径增宽，流量增大，桡动脉内中膜厚度增加（P〈0.05），桡动脉内径缩小，但差异无统计学意义（P〉0．05）。结论彩超监测尿毒症患者动静脉内瘘血管通道的状况和流量变化对于临床血液透析方案的选择及调整具有重要意义。

Objective To study of vascular access in uraemic patients with internal arteriovenous fistula （AVF） operations 1 year later. Methods Twenty -four uraemic patients, the internal diameter of cephalic vein and radial artery and orificium fistulae were consecutively measured by color Doppler uhrasonography at two weeks and one year after AVF operations. The fluence of AVF and IMT of radial artery were also consecutively measured. Results The patients one year after AVF operations compared with two weeks after AVF operations, internal diameter of cephalic vein and orificium fistulae increased （ P 〈 0.05 ） , the IMT of radial artery was significantly thicker （ P 〈 0. 05 ） ,the fluence of AVF also increased （ P 〈 0.05 ）, and in contrast, the internal diameter of radial artery was smaller （ P 〉 0.05 ）. Conclusion Color Dopple uhrasonography has important clinical diadynamic value for the vascular access in uraemic patients after AVF operation.
