Endarterectomy versus stenting in patients with prior ipsilateral carotid artery stenting

We have reported adverse event rates for CEA and CAS after prior CAS and shown no significant difference in perioperative and 1-year outcomes between both groups. However, CEA is offered to patients who are more severely ill than redo-CAS, resulting in significantly higher absolute mortality. We recommend avoidance of CEA especially in asymptomatic patients with serious systemic disease. Tight management of diabetes and smoking cessation remain potent targets for outcomes improvement in redo-CAS patients.
