Will Carotid Angioplasty Become the Preferred Alternative to Staged Or Synchronous Carotid Endarterectomy in Patients Undergoing Cardiac Surgery?

In the absence of randomized trials, the optimal management of patients who present with concomitant carotid and coronary artery disease remains an enduring controversy, with much of the debate revolving around whether staged or synchronous carotid endarterectomy (CEA) will reduce peri-operative morbidity and mortality after cardiac surgery. Although encouraging results have been reported using either strategy, there remains no consensus as to which is preferable. More recently, however, carotid artery angioplasty with stenting (CAS) has emerged as a potential alternative to CEA. In 'high-risk for CEA' patients, CAS has shown comparable short and tong-term outcome rates to CEA. Accordingly, CAS followed by cardiac surgery could offer a less invasive (and safer) therapeutic option in cardiac patients. This paper reviews the evidence to date supporting the use of CAS + CABG, white highlighting potential situations where such a strategy might be harmful. In particular, it will focus on how the need for dual antiplatelet therapy after CAS can be balanced with avoiding unnecessary bleeding complications after cardiac surgery.
