Intra-aortic counterpulsation during carotid stenting

Postprocedural hypotension following endovascular stent placement of carotid artery disease (CAS) predicts increased in-hospital complications and long-term risk of death. Intra-aortic balloon counterpulsation (IABP) both increases mean arterial pressure and cerebral blood flow and therefore possibly reduces complications due to hemodynamic instability during and after CAS. In this study, we describe the use of IABP in a patient with severe depression of left ventricular function due to diffuse coronary artery disease undergoing CAS. Controlled studies are necessary to demonstrate a potentially protective role of IABP in high-risk CAS patients.
