Abstract:
Objective To assess the efficacy and safety of ultrasound-guided percutaneous transluminal angioplasty (PTA) for treatment of stenosis of autogenous arteriovenous fistulas in maintenance hemdialysis patients. Methods From September 2016 to August 2017, thirty patients with autologous arteriovenous fistula (AVF) stenosis diagnosed in Guangzhou First People′s Hospital underwent PTA under the guidance of ultrasound for the first time. The vascular diameter of AVF stenosis and the blood flow of AVF before and after operation were evaluated. During the follow-up period,the patency time and complications were recorded. Results In 93. 3%( 28/30) patients, primary ultrasound-guided PTA procedures were successfully performed. The internal diameter of the stenosis increased from (1. 62±0. 30) mm preoperatively to (3. 61±0. 66) mm postoperatively (t＝18. 205,P＜0. 001),and the natural blood flow increased from (270. 0±36. 5) ml/min preoperatively to (611. 4±46. 6) ml/min postoperatively (t＝50. 221,P＜0. 001). The post-intervention primary patency rates at 90 and 180 d were 96. 4%(27/28) and 85. 7%(24/28), respectively. There was no rupture of the vein,or other severe complication during the PTA procedure. One patient had perilesional swelling,and one patient had extravasation after the PTA procedure. Conclusion Ultrasound-guided PTA is a safe and effective method for treatment of stenosis of autogenous arteriovenous fistulas in maintenance hemdialysis patients.
