Ultrasound Evaluation of Balloon Angioplasty for the Treatment of Autogenous Arteriovenous Fistula Anastomotic Stenosis: Ultrasound evaluation of PTA for AVF anastomotic stenosis

The aim of the study was to investigate the effectiveness of ultrasound in the evaluation of percutaneous balloon angioplasty (PTA) for the treatment of autogenous arteriovenous fistula (AVF) stenosis. 40 patients with AVF stenosis participated in the study who were treated with regular hemodialysis in the First Hospital of Jilin University. Among the many indicators, we selected radial blood flow, radial artery resistance index, and anastomotic diameter as monitoring indicators. The results of preoperative, immediate postoperative, postoperative 1 day, 3 days, 7 days, and 14 days were used to find the trend of the indicator and determine the best monitoring time point. Finally, we found morphological indicators and hemodynamic parameters changed significantly after operation; no obvious statistical difference between 1 day postoperative and other postoperative monitoring time points were founded. So, ultrasonography has unique advantages in hemodynamics and morphological examination. It can evaluate the functional status of AVF and the efficacy of PTA accurately, and we believe that the first day after surgery is the best time to monitor.
