Concomitant coronary artery bypass and major noncardiac surgery.

Concomitant cardiac procedures performed in conjunction with coronary bypass have become commonplace, but not concomitant noncardiac procedures. Bernhard and associates were the first to report concomitant coronary bypass and carotid endarterectomy. This series, begun in 1971, consists of 71 noncardiac procedures performed concomitantly with coronary bypass on 68 patients. Thirty-seven procedures were performed for associated vascular disease, including carotid endarterectomy (25 patients) and resection of abdominal aortic aneurysm (three patients). Other concomitant problems included are thymoma, bronchogenic carcinoma, and hiatal hernia. The operative mortality rate of 2.9 percent compares very favorably with that of 1.7 percent in our group of patients having isolated coronary artery bypass. A plea is made for consideration of concomitant surgery in patients with operable coronary heart disease who have an additional serious noncardiac surgical disease.
