Abstract:
Objective To study the clinical events and risk factors of in stent restenosis (ISR) during the >1 year follow-up period after vertebral artery stenting.Methods Forty-six patients with 48 stents implanted from the Shaoxing No.2 Hospital between January 2010 and October 2016were divided into ISR group (n=8) and ISR-free group (n=38) or clinical events group (n=8)and clinical events-free group (n=38).The influencing factors for their long-term clinical outcome were analyzed after vertebral artery stenting.Results The mean stenosis length was (7.7 ± 4.6mm,the stenosis severity was 80.7%±14.2%,and the residual stenosis was 3.0%±8.4% before stenting.The mean angiographic follow-up time was 31.6±20.8 months,during which ISR occurred in 8 patients (17.4%).The mean clinical follow-up time was 53.8±27.0 months,during which clinical events occurred in 8 patients (17.4%).Survival analysis showed that ISR usually occurred in the first 20 months and no clinical events occurred in 23 patiemts (50.0%) after vertebral artery stenting.The stenosis was significantly longer in ISR group than in ISR-free group (6.00±2.00 mm vs 2.76±4.14 mm,P=0.003).The diameter of stents was significantly shorter in clinical events group than in clinical events-free group (3.53±0.93 mm vs 4.18±0.67 mm,P=0.024).Conclusion The long-term clinical follow-up outcome is associated with the length and diameter of stents in patients after vertebral artery stenting.
