[Single-staged operation for the patients with concomitant diseases of coronary and carotid arteries].

The authors describe four cases with concomitant coronary and carotid severe stenosis operated by combined procedure. As the cerebral revascularization, carotid endarterectomy (CEA) was performed for three patients, while carotid artery bypass grafting was performed for the other one. In one patient with bilateral carotid stenosis, percutaneous transluminal stenting of the right internal carotid artery was performed one day before combined left CEA and coronary artery bypass grafting (CABG). Both perioperative myocardial infarction and neurological complication could be avoided in each case. When a CABG candidate also has significant extracranial carotid stenosis with clinical symptoms, combined cerebral revascularization and CABG is desirable.
