Predictors of restenosis after successful carotid artery stenting

This study was performed to determine the risk factors for restenosis after successful carotid stenting. Of 222 patients who underwent successful carotid stenting, 179 (81%) had a follow-up study (carotid ultrasound and/or angiogram). Restenosis rate was 6.7% (14 of 195) for vessels. By univariate analysis, restenosis rates were significantly different between men and women (4% vs 15.4%, p = 0.018) and age < or =75 versus >75 years (3.8% vs 16%, p = 0.013). By multivariate analysis, older age (odds ratio [OR] 1.107, p = 0.015), female sex (OR 3.519, p = 0.001), implantation of multiple stents (OR 2.363, p = 0.019), and postprocedural percent stenosis (OR 1.067, p = 0.054) were associated with increased incidence of restenosis.
