Appropriatezza degli interventi simultanei di endoarteriectomia carotidea e rivascolarizzazione miocardica [Appropriateness of simultaneous carotid endarterectomy and coronary revascularization]

Background. The presence of significant carotid artery disease in patients undergoing coronary artery bypass grafting has been reported to be as high as 17%. The optimal management of patients with significant coronary and carotid artery disease remains controversial. In this study, we analyze our recent experience with patients who underwent synchronous carotid endarterectomy (CEA) and coronary artery bypass grafting. Methods. We reviewed the early outcome of 68 patients (56 males, 12 females, mean age 71.1 years, range 53-88 years) who underwent simultaneous CEA and coronary artery revascularization between January 2005 and June 2007. The frequency of unstable or ulcerated plaques was determined in symptomatic and asymptomatic patients. Results. Death for myocardial infarction occurred in 3 patients (4.4%). Stroke was found in 1 patient (1.4%). Combined 30-day stroke/mortality rate was 5.8%. The frequency of unstable or ulcerated plaques was 60.3% (41/68). An unstable stenosis was present in 23 out of 42 asymptomatic patients (54.7%). Conclusions. Patients suffering from a concomitant coronary and carotid artery occlusive disease represent a high-risk population whose management is still controversial. A modern approach to combined CEA and coronary artery bypass grafting may be safe. The high frequency of unstable carotid lesions in asymptomatic patients suggests to treat every stenosis >75 % in candidates to coronary artery bypass grafting. Carotid artery stenting should be avoided in the majority of cases, considering the possibility of unstable carotid stenosis and the atherosclerotic involvement of aortic arch.
