Stroke, myocardial infarction, and survival during long-term follow-up after carotid endarterectomy.
Epidemiological data on 211 patients undergoing 256 carotid endarterectomies were reviewed, and current data for the 205 perioperative survivors were analyzed by the actuarial method. The median follow-up period was 7.0 years (range: 1 month to 23.2 years). Seven percent of patients were lost to follow-up. Actuarial survival was 77% (5 years) and 49% (10 years), but lower than for the general population. Late stroke occurred in 27 patients (13%) (fatal in 9), being ipsilateral to an endarterectomy in only 10 (4.9%). The annual ipsilateral stroke rate (0.41%), comparable to that of the general population, suggests protection from subsequent stroke. Myocardial infarction occurred in 69 patients (34%), and accounted for 49% of late deaths.
