Simultaneous Carotid Endarterectomy and Cardiac Surgery: Early Results of 386 Patients

Abstract

Background The occurrence of severe carotid artery disease in more than 12% of patients requiring coronary artery bypass grafting (CABG) results in a discrepancy concerning best treatment for both diseases. We reviewed the early outcome of patients with CABG and/or valve replacement (VR) and simultaneous carotid endarterectomy (CEA).

Methods We retrospectively evaluated 386 patients after simultaneous operation between 7/1994 and 9/2010. Total 326 patients received isolated CABG, 56 CABG and/ or VR, 4 aortic surgery. Mean age was 68.3 years (range: 45 to 87). Male patients were 229. Severity of stenosis at operated side was 70 to 80% in 167, 80 to 99% in 219 patients. Total 164 patients showed bilateral carotid stenosis, 32 had contralateral occlusion. We analyzed risk factors, morbidity, incidence of neurological events, and 30-day mortality.

Results Perioperative stroke with hemiplegia occurred in 10 patients (2.6%). Three patients experienced PRIND, seven TIA. A 30-day mortality was 5.2%. Total 8 deaths were cardiac related, 10 due to extracardial reasons, and 2 patients developed a cerebral death.

Conclusions Simultaneous CEA and cardiac surgery can be performed with a low risk for neurological complications and acceptable mortality. Occlusion of contralateral carotid artery could be identified as an evident predictor for increased neurological complications.
