Abstract:
Objective To explore the primary patency rate and impact factors of autogenous arteriovenous fistula success after preop-erative ultrasound-guided percutaneous transluminal angioplasty(PTA)in patient with small-caliber artery on maintenance hemodialysis(MHD).Methods We included 128 end-stage renal disease patients with distal radial artery diameters＜1.5mm,treated with ultra-sound-guided percutaneous transluminal angioplasty(PTA)to establish an arteriovenous fistula(AVF)at Guizhou Medical University Affiliated Tumor Hospital between January 1,2019 and December 31,2021.Patients were classified into failure and patency groups based on AVF patency.We assessed the surgical technical success rate,clinical success rate,and primary patency rate,and analyzed factors af-fecting AVF failure.Results In these patients,the technical success rate of AVF creation after PTA was 91.4％,the clinical success rate was 83.6％,and the 12-month primary patency rate was 54.4％.Female gender,diabetes,and a preoperative radial artery diame-ter ≤ 1 mm were independent risk factors for AVF failure after PTA(P＜0.05).Conclusion Establishing AVF after PTA dilation of ar-teries in patients with small-caliber arteries undergoing maintenance hemodialysis has a high technical success rate and primary patency rate.Diabetes,female gender,and preoperative radial artery diameter ≤1.Omm are independent risk factors for AVF failure in these pa-tients.
