Abstract

Background and Purpose

Previous clinical studies have suggested that patients with carotid stenosis with high surgical risk features may fare better with carotid artery stenting or aggressive medical therapy. The extent to which carotid endarterectomy is still being performed in this group of patients is unclear.

Methods

A retrospective audit was performed among 4 hospitals over a 2-year period. The proportion of high surgical risk patients was compared and the in-hospital stroke, myocardial infarction, and death rates were compared among conventional and high surgical risk patients.

Results

Three hundred thirty-five carotid endarterectomy operations were performed (63% asymptomatic) with 37.9% being high surgical risk subjects. The stroke, myocardial infarction, and death rate was 4.6% in conventional risk subjects and 10.2% in high surgical risk patients (P < 0.05). The only hospital with multidisciplinary carotid conferences had the lowest proportion of carotid endarterectomy operations in asymptomatic patients.
