Repeat Revascularization over 10 Years Following Carotid Endarterectomy or Carotid Stent Placement: An Analysis of Carotid Revascularization Endarterectomy Versus Stenting Trial.
2021
Objective To identify rates of and factors associated with repeat revascularization in a large cohort of patients prospectively followed over 10 years in Carotid Revascularization Endarterectomy versus Stenting Trial. Methods We compared the effect of carotid angioplasty and stenting (CAS) versus carotid endarterectomy (CEA) on risk of repeat revascularization after adjusting for age, sex, symptomatic status, and initial severity of stenosis (≥70% vs. Results Repeat revascularization was performed in 90 (3.9%, 95% confidence interval [CI] 3.1%–4.8%) of 2318 patients; 6 (6.7%, 95% CI 2.5%–14.0%) patients experienced the composite end point of any stroke, myocardial infarction, or death within 30 days after repeat revascularization. There was no difference in risk of repeat revascularization in patients who underwent CAS (compared with CEA) as the index procedure (hazard ratio 0.92, 95% CI 0.69–1.23, P = 0.5765). Patient’s age (hazard ratio 1.01, 95% CI 1.01–1.02, P Conclusions A low rate of repeat revascularization was seen without any significant difference among patients who underwent CEA or CAS over 10 years. The 6.7% rate of composite end point within 30 days after procedure highlights the need for standardizing the indications for repeat revascularization.
