Background and Purpose— To assess the benefits of carotid artery stenting before coronary artery bypass surgery to reduce the risk of stroke occurring during the cardiac procedure.

Methods— A prospective cohort study was performed in patients undergoing carotid artery stenting before coronary artery bypass surgery, or combined bypass and valve replacement procedures, to assess the procedures effectiveness in stroke prevention. Outcome measures including 30-day post stenting and cardiac surgery neurological complication and all-cause mortality rates were assessed.

Results— A total of 52 patients were included. Two patients underwent aortic valve replacements at the same time as coronary revascularization. No neurological complications occurred because of the stenting procedure. One cardiac death not related to coronary artery bypass surgery occurred in the 30-day follow-up period for the stent procedure. An additional 6 (11.5%) outcome events (3 strokes and 3 deaths) occurred in the 30-day follow-up period after the cardiac procedure. Three patients died of cardiac causes while awaiting their cardiac bypass procedure.

Conclusions— Our results are comparable to those in patients that undergo staged or combined carotid endarterectomy before cardiac surgery. Our small cohort study adds to the limited world literature on the subject but is not sufficiently powered to recommend alterations in practice.

Key Words: cardiac bypass • carotid endarterectomy • stents
