Comparison of drug-coated balloon angioplasty versus common balloon angioplasty in hemodialysis patients with arteriovenous fistula stenosis: A meta-analysis of randomised controlled trials

Abstract

Drug-coated balloons (DCBs) have been used in dialysis patients with arteriovenous fistula (AVF) stenosis, but whether they have advantages over ordinary balloons is still controversial. A meta-analysis was designed to investigate the safety and efficacy of DCBs and common balloons (CBs) in the treatment of AVF stenosis, with a registration in INPLASY (INPLASY202280112). A total of 15 randomized controlled trials (RCTs) were included in this meta-analysis. The results showed that the DCB group had a higher first-stage patency rate of the target lesion 6 months and 12 months after surgery, and the difference was statistically significant. There was no statistically significant difference in all-cause mortality between the two groups at 6 months and 12 months.
