The optimal surgical approach to the patients with coronary artery disease combined with carotid artery stenosis is controversial. We report two cases of successful surgical management of the patients with combined obstructive coronary and carotid artery disease. The first case was a 69-year-old female who had unstable angina pectoris and a past medical history of left carotid endarterectomy. She was revealed to have triple vessel coronary disease and nearly total occlusion of right internal carotid artery. She was undergone staged right carotid endarterectomy 10 days before coronary bypass surgery. The second case, a 54-year-old male with a past medical history of left hemiparesis and dysarthria, was admitted due to unstable angina pectoris. He was revealed to have triple-vessel coronary disease and more than 90% stenosis of left internal carotid artery and 50% stenosis of right internal carotid artery. In the latter case, a combined coronary bypass surgery and left carotid endarterectomy was done. In both cases, postoperative neurologic complications were not observed.
