Carotid endarterectomy in symptomatic and asymptomatic patients aged 75 years or more: Perioperative mortality and stroke risk rates.

The aim of this retrospective study was to determine whether age per se constitutes a contraindication to surgery in the elderly patient undergoing carotid endarterectomy (CEA) with regard to operative mortality and stroke risk morbidity. During an 8-year period, 96 patients aged 75 years or more underwent 103 CEAs. The age range was 75 to 89 years, with a median age of 79 and a mean age of 79.4 years. Fifty-nine CEAs with patch closure and 44 carotid eversion endarterectomies and reimplantation were performed for symptomatic (70.9%) and asymptomatic (29.1%) carotid lesions under general anesthesia and with continuous perioperative electroencephalographic (EEG) monitoring. In light of the efficacy and success achieved in this experience, advanced age does not seem in itself to contraindicate the performance of CEA; the surgical risk for elderly patients appears sufficiently low to justify the operation. A more aggressive approach may be warranted in elderly patients because of the morbidity and cost of the disease that it effectively prevents.
