title: Operative strategy in combined coronary and carotid artery disease.
abstract: In the period between the opening of our heart center in November 1984 and May 1986, 2001 cardiac operations were performed with the aid of cardiopulmonary bypass. Almost three quarters (73.5%, n = 1471) of the patients had coronary artery disease and 20% (n = 359) had acquired valvular heart disease. In 47 of 1471 patients who underwent coronary artery bypass grafting, a simultaneous carotid endarterectomy was performed. They included 36 men and 11 women, aged between 51 and 78 years (mean 64 years). Preoperatively, 12 patients had cerebrovascular symptoms and 35 were neurologically asymptomatic. Twenty-three had unilateral carotid stenosis and 24 had bilateral or multiple vessel disease of the extracranial arteries. All except four patients had triple-vessel coronary artery disease. In three patients with aortic valve disease, coronary bypass, carotid endarterectomy, and aortic valve replacement were performed simultaneously. Cardiopulmonary bypass was instituted before carotid endarterectomy was performed, with mild hypothermia and hemodilution for added protection. Electroencephalographic monitoring was used throughout the operation. Forty-six of the 47 patients survived the operation without neurologic or cardiac complications. One patient had a neurologic deficit with hemiplegia and coma, which was lethal. We conclude that simultaneous endarterectomy of significant extracranial artery stenosis in candidates for coronary bypass is a method safe enough to justify its routine use.
