PUJOL LEREIS, Virginia A. et al. Morbidity and mortality of carotid endarterectomy. Medicina (B. Aires) [online]. 2011, vol.71, n.5, pp.449-453. ISSN 0025-7680.

Clinical trials in academic centers with high selected surgeons have demonstrated the effectiveness of carotid endarterectomy (CE) in addition to best medical treatment in symptomatic and asymptomatic patients with moderate to severe stenosis. International guidelines recommend that the procedure should be done in centers with morbidity and mortality rates of less than 6% for symptomatic and 3% for asymptomatic patients. We evaluated the morbidity and mortality of CE in our institution. This was defined by the presence of stroke, myocardial infarction and/or death within 30 days of surgery. Surgery was indicated in symptomatic patients with stenosis greater than 50%. For asymptomatic or symptomatic patients with stenosis ≤ 50% treatment was decided on a case-by-case basis. All patients were examined by a neurologist with and a cardiologist before and after the procedure. Intraoperative monitoring with transcranial Doppler was routinely used in patients with adequate ultrasonic window. We evaluated 306 procedures. No deaths occurred. Perioperative morbidity was 2.6% for both, symptomatic and asymptomatic subjects. These numbers compared favorably with those reported by other centers in Latin America and Europe. In conclusion, CE can be performed in routine clinical practice with morbidity and mortality results within those recommended by international guidelines.
