Abstract:
Objective To explore the impact of vascular calcification on patency rate of arteriovenous fistula(AVF)after ultrasound-guided percutaneous transluminal angioplasty(UG-PTA)for stenosis.Methods Forty-eight chronic kidney disease patients who underwent maintenance hemodialysis(HD)and received UG-PTA since autologous or artificial AVF stenosis were retrospectively enrolled.The patients were divided into calcification group(n=21)and non-calcification group(n=27)according to ultrasonic findings of AVF calcification or not.The technical success rate of UG-PTA,the clinical success rate and UG-PTA related adverse events were recorded.Ultrasound was performed to evaluate the patency of AVF 3,6,9,12,24 and 36 months after UG-PTA,and the primary and secondary patency rates were calculated.Kaplan-Meier survival curves were used to analyze the patency rates of AVF.Results UG-PTA was successfully performed in all 48 cases.All patients completed more than 3 times effective HD,the technical and clinical success rate both of 100%(48/48).No serious adverse event occurred.In calcification group,the primary patency rate 3,6,9,12,24 and 36 months after UG-PTA was 75.89%,37.95%,37.95%,27.10%,14.46%and 0,and the secondary patency rate was 95.24%,95.24%,95.24%,89.95%,83.03%and 83.03%,respectively,while in non-calcification group the primary patency rate was 92.31%,73.08%,57.69%,53.85%,36.15%and 36.15%,and the secondary patency rate was 100%,100%,100%,100%,95.24%and 95.24%,respectively.After UG-PTA,the primary patency rate in calcification group was lower than that in non-calcification group(P＜0.05),but there was no significant difference of the secondary patency rate between groups(P＞0.05).Conclusion Calcification was a risk factor for primary patency rate of AVF after UG-PTA for stenosis,but had no significant impact on the secondary patency rate.
