Surgical management of concomitant carotid and coronary artery occlusive disease

Abstract

The management of concomitant coronary and carotid disease is controversial. We report our experience of simultaneous coronary artery bypass surgery and carotid artery endarterectomy on 70 consecutive patients (34 males and 36 females) with a mean age of 68 years. The oldest patient was 91 years old. The average percent of carotid artery stenosis was 86% (range 60%–99%). The average number of grafts per patient was 3.35 (range 1–6). Two patients experienced postoperative strokes (2.86%), 1 had a perioperative infarct (1.42%), and 4 died in the hospital (5.7%). The simultaneous approach offers the advantage of shorter hospital stays, decreased anesthesia exposure, and significant cost savings. The causes of death include stroke, renal failure, and bowel infarction. This review indicates the simultaneous approach has a higher incidence of adverse outcomes compared with elective carotid endarterectomy or elective coronary artery bypass surgery. These patients, however, are at significantly higher risk due to their poor medical conditions, extensive atheromatous disease, and often emergent medical condition.
