[Novel stent/CEA strategy for patients with bilateral carotid artery stenosis and coronary artery disease: report of 2 cases].

Recently, there are increasing numbers of patients with occlusive carotid artery disease and coronary artery disease. Simultaneous or two-staged surgery for both lesions has been recommended for these patients to reduce the incidence of perioperative complications. However, therapeutic options for the patients with bilateral carotid artery stenosis and coronary artery disease have not been established. In this report, we describe two patients who successfully underwent carotid endarterectomy (CEA) and carotid artery stenting (CAS) on each carotid artery in parallel with coronary artery bypass grafts (CABG). A 49-year-old male with severe stenosis of the bilateral internal carotid artery (ICA) and heart failure underwent CAS on the right side. Next day, he successfully underwent CABG and CEA on the left side at the same time. A 62-year-old male with severe stenosis of the bilateral ICA and coronary artery disease underwent CAS on the right side and CEA on the left side with an interval of 7 days. Subsequently, CABG was performed uneventfully. No perioperative complication occurred in either patient. The results suggest that combination therapy of CAS and CEA would be a valuable option for patients with complex carotid/coronary artery diseases.
