Evaluation of early efficacy of ultrasound-guided percutaneous transluminal angioplasty in treatment of arteriovenous fistula stenosis / 中国介入影像与治疗学

ABSTRACT

Objective: To evaluate the efficacy of ultrasound-guided percutaneous transluminal angioplasty (PTA) in the treatment of arteriovenous fistula (AVF) stenosis for hemodialysis. Methods: A retrospective analysis of the clinical data of 24 dialysis patients with stenosis of forearm AVF treated with ultrasound-guided PTA was performed. Preoperative and postoperative diameters of stenosis were compared. Kaplan-Meier survival analysis was used to evaluate patency rate. Results: All the operations of 24 patients achieved technical success with a success rate of 100%(24/24). No patient died during the perioperative period, no complications such as pseudoaneurysm at the puncture site and subcutaneous hematoma occurred, except for 1 case of thrombosis. The primary patency rate was 87.50%(21/24), 83.33%(20/24), 79.17%(19/24), 58.33%(14/24) at 3, 6, 9 and 12 months, respectively. Conclusion: Ultrasound-guided PTA is a safe and minimally invasive treatment for AVF stenosis with a good early result.
