Management of concomitant occlusive disease of the carotid and coronary arteries

Abstract

With the advent of direct coronary artery revascularization, the high mortality rate from cardiac disease associated with carotid endarterectomy can be favorably altered by simultaneous or staged revascularization for combined lesions. The choice for combined or sequential procedures is determined by the severity of the disease both clinically and anatomically in each system. Review of 32 patients with both severe coronary and carotid occlusive disease established that selective surgical intervention has been successful, with no deaths and only minimal morbidity. Simultaneous revascularization was carried out in 8 patients with preinfarctional angina, significant left main lesion or triple vessel disease producing a functional lesion of the left main coronary artery, and tight carotid lesion. Staged operations were performed in the remaining 24 patients. Priority of staging was determined by the extent of disease in each system.
