Abstract

Restenosis after carotid endarterectomy (CEA) is a potential complication after surgery for carotid stenosis. Stroke after CEA is a debilitating complication secondary to restenosis, and modification of postoperative care may be necessary to decrease the incidence of postoperative stroke after CEA. We sought to identify the clinical and patient factors that are associated with this complication. A retrospective analysis of all neurosurgical patients who underwent CEA for symptomatic or asymptomatic carotid stenosis was performed. Factors were compared against the outcome variable in a univariate analysis. A multivariate logistic regression model was used to identify independent predictive variables. We used Kaplan-Meier analysis to compare the effect of the variables on long-term event-free survival. A total of 273 CEA procedures and their outcomes were analyzed with a mean follow-up of 50.7 months. Twenty-one patients had restenosis (7.6%). Rates of restenosis and restenosis-free survival were analyzed with Kaplan-Meier curves (log-rank test). In the multivariate model, a family history of stroke was the only variable that was significantly associated with restenosis after CEA. Our findings suggest that a family history of str...Continue Reading
