Abstract:
Objective:To analyze the effect of percutaneous transluminal angioplasty (PTA) in the treatment of autogenous arteriovenous fistula (AVF) stenosis and influcing factors of restenosis/loss of function after PTA.Methods:The medical records of 104 patients with AVF stenosis treated by PTA in People′s Hospital of Huadu District from March 2019 to July 2020 and the 1-year follow-up were retrospectively analyzed. Kaplan-meier curves were used to analyze the primary patency rates at 3 months, 6 months and 1 year. COX regression was used to analyze the influencing factors of restenosis/loss of function after PTA.Results:The primary patency rates of AVF at 3, 6 and 12 months after PTA were 86.2%, 83.2% and 64.7%, respectively. Guide wire entry into the distal end of radial artery, the use of two balloons in stepwise mode, postoperative dilatation diameter, and dialysis blood flow after PTA were independent risk factors for restenosis/loss of fuction after PTA for AVF stenosis (all P<0.05). Conclusions:The guide wire into the distal end of the artery and passive use of more than two balloons are important factors affecting AVF restenosis/loss of function after PTA .
