Drug-coated balloon angioplasty for symptomatic vertebral artery origin stenosis: a real-world analysis of efficacy and predictors for bailout stenting

Objective: This study aims to evaluate the preliminary efficacy and safety of drug-coated balloon (DCB) angioplasty for treating symptomatic vertebral artery origin stenosis (VAOS) in a real-world setting and to investigate potential factors necessitating intraoperative bailout stenting (BS). Methods: -index) and the Hosmer-Lemeshow goodness-of-fit test. Results: = 0.9158). Conclusion: DCB angioplasty was associated with favorable angiographic durability in symptomatic VAOS, with similar long-term patency between balloon-only and bailout stent strategies. Higher diastolic blood pressure, and concomitant carotid stenosis were associated with bailout stenting.
