SUMMARY The indication of carotid endarterectomy depends on the risk of death or stroke resulting from surgery in hospitals where they are performed. The aim of this study was to assess morbimortality resulting from these patology in public and private hospitals with low volume of surgeries. In 5 hospitals which over the last four years had a surgical volume of 150 patients or less, 173 medical records were analyzed retrospectively. The following were considered: health conditions prior to surgery, incidence of stroke, death rate, medical complications which occurred in the first 30 days. Of the studied patients, 3 died (1.7%), 2 for neurological reasons and 1 for cardiovascular reason, 4 (2.3%) suffered a stroke after surgery, being the global morbimortality rate over 30 days, 4.1%. Two patients suffered an acute myocardial infarction and 2 (2.3%) developed angina pectoris. Hemodynamic instability after surgery was the most frequent complication (33.3%). Three patients suffered cerebral hyperperfusion syndrome after surgery, related to arterial hypertension (p<0.01%). In Collective Medical Assistance Institutions there was a higher rate of surgeries involving asymptomatic patients at low cardiovascular risk, a greater use of beta blockers, and a higher incidence of hypotension suffered after surgery when compared with public institutions. Global morbility and mortality are consistent with international standards for low-volume hospitals. Hemodynamic instability was the most common complication. The major causes of death were neurological complications. A higher rate of symptomatic patients was found in public servicies. Arterial hypertension and use of beta blockers were more common in private centers.
