Coexisting carotid stenosis in patients undergoing cardiac surgery: indications and guidelines for simultaneous...

The coexistence of critical carotid stenosis with coronary artery or valvular heart disease occurs in a small percentage of patients requiring open heart surgical procedures. Recognition of such combined lesions by noninvasive carotid testing identifies patients at risk for neurologic events. Our experience with 62 patients having combined simultaneous carotid and cardiac operations among 2,400 open heart surgery patients was compared with the results in 110 patients with only carotid endarterectomy operations. The outcomes indicated that carotid endarterectomy can be performed simultaneously with open heart surgical procedures with morbidity and mortality rates similar to those of isolated cervical artery operations. Thus, patients with significant coexisting carotid artery disease defined with specific criteria and coronary artery disease need not be exposed to cerebral ischemic events or to myocardial infarctions that often accompany staged operations.
