Abstract
Hemodialysis is an important method to maintain the life of patients with ESRD (end-stage renal disease). The establishment of the AVF can meet the requirements of high blood flow during hemodialysis. However, AVF can narrow and affect blood flow during use. This study was aim to evaluate the therapeutic effect of ultrasound-guided PTA (percutaneous transluminal angioplasty) on AVF stenosis by color doppler and contrast-enhanced ultrasound and to investigate the recurrence factors by multivariate logistic regression analysis. A total of 52 ESRD patients were included in this study. The results of ultrasound imaging showed that after the ultrasound-guided PTA treatment, the diameter of AVF fistula, average flow velocity and flow rate were significantly higher than those before treatment (p < 0.05) and the AVF stenosis caused by intimal thickening with or without thrombosis is prone to restenosis after surgery.
