Synchronous CEA and CABG in asymptomatic carotid artery stenosis: A case study

In the United States, there were 213,700 coronary artery bypass grafting (CABG) surgeries and 102,700 carotid endarterectomies (CEA) in 2011. Combined CEA and CABG surgeries are lower than either CEA or CABG, with an estimated 1,370 surgeries in 2012. There is some literature which supports that the surgeries can be performed safely together (referred to as combined, synchronous, tandem, or concomitant procedures). The purpose of this article is to describe the merits and potential complications involved with undergoing synchronous carotid artery and coronary artery bypass procedures. This purpose will be addressed by examining a case study of a patient who completed a synchronous procedure and by also reviewing the literature which addresses the benefits versus the risks associated with the synchronous procedures. Some studies found an increased incidence of perioperative and postoperative risks such as stroke, myocardial infarction, and death with the combined procedures, whereas some studies found no difference in the risks when the operations were performed sequentially. Combined or synchronous coronary artery bypass and carotid artery endarterectomy may be a safe surgical option for a specific subset of patients.
