Drug-Coated Balloon for Arteriovenous Access Stenosis in Hemodialysis Patients

Hemodialysis access stenosis is a pervasive problem that occurs due to the physiology of high-flow circuit. Stenosis endothelial and smooth muscle injuries result in neointimal hyperplasia. Percutaneous transluminal angioplasty standard treatment for dialysis access-induced stenosis. Unfortunately, it also associated with vessel wall trauma, which causes further intimal hyperplasia restenosis. Data from randomized controlled trials (RCTs) systematic reviews use drug-coated balloons (DCBs) have been controversial. While several single-center or RCTs reported safe effective DCBs, conflicting results still exist. Furthermore, paclitaxel known be an increased mortality risk. Herein, we review current evidence on role DCBs
