Staged or combined carotid endarterectomy (CEA) offers the potential benefit of decreased neurological morbidity during and after cardiac surgery; however, the strategy for treating unstable high-risk patients, who need urgent coronary artery surgery, remains unresolved. We report in-hospital and 30-day outcomes of 23 consecutive patients admitted with unstable angina, who underwent carotid angioplasty and stenting (CAS) immediately prior to urgent coronary artery surgery, from October 2007 to October 2008. Aspirin and unfractioned heparin were administrated during carotid stenting and clopidogrel was only started after cardiac surgery. All patients remained event-free during and immediately after the carotid stenting procedure. One patient died due to sepsis 22 days after cardiac surgery. There was neither stroke nor myocardial infarction at follow-up. No patient needed a cardiac or carotid re-intervention. This new approach (combined carotid stenting and coronary artery surgery) provides a less radical intervention, can be performed with a low periprocedural complication rate and may become a valuable alternative in the treatment of high-risk patients with combined carotid and cardiac disease.
