Y. Suematsu et al., Conventional coronary artery bypass grafting in patients with total occlusion of the internal carotid artery, HEART VESS, 15(6), 2000, pp. 256-262
The number of patients with coexisting disease of the coronary and carotid
arteries is increasing. Patients with total occlusion of the carotid artery
may have a higher risk of stroke during cardiopulmonary bypass surgery and
in the perioperative period. We report our results for coronary artery byp
ass grafting (CABG) in patients with total occlusion of the carotid artery.
We examined 269 patients who underwent carotid artery duplex scanning (CAD
S) before CABG between November 1995 and January 1998. Among them. 11 patie
nts (4.1%) had total occlusion of a carotid artery. Four patients underwent
elective CABG and five underwent emergency CABG. One patient underwent ana
stomosis of the superficial temporal artery to the middle cerebral artery (
STMC) and one patient underwent a combined CABG and carotid endoarterectomy
(CEA) procedure. A transient neurological event occurred in only one patie
nt (9.1%). The other patients recovered uneventfully. Our results suggest t
hat CABG can be performed without stroke in patients with total unilateral
occlusion of a carotid artery using our strategies.
