Paclitaxel drug-coated balloon angioplasty for patients with symptomatic vertebral artery origin stenosis

Objective To evaluate the efficacy and safety of paclitacxel drug-coated balloon(P-DCB)angioplasty for the patients with symptomatic vertebral artery origin stenosis(VARS).Methods The clinical data of 43 consecutive patients with symptomatic VARS who underwent P-DCB angioplasty from December 2017 to June 2019 were analyzed retrospectively.Results All the procedures were completed successfully,and the success rate was 100%.The immediate postoperative stenosis rate[(12.03±2.15)%]was significantly lower than that[(86.32±10.26)%]before the operation(P<0.05).Arterial dissection occurred in 1 patient during the perioperative period.The follow-up ranged from 12 months to 16 months,with an average of 13.5 months.The symptomatic improvement rate was 95.3%(41/43).There was no statistical difference between the follow-up stenosis rate[(16.1±3.12)%]and the immediate postoperative stenosis rate(P>0.05).Restenosis occurred in 5 patients and the restenosis rate was 11.6%(5/43).Conclusion P-DCB angioplasty is a safe and good method for treatment of the patients with symptomatic VARS.
