Background and Objective: Due to increased life expectancy, the risk profile of the patients undergoing cardiac surgery changed dramatically. This is especially important in case of concomitant coronary artery disease and carotid artery stenosis (CAS). Careful decision making and appropriate surgical strategy in these patients is critical for the success of the operation. Controversy about relationship between staged and concomitant carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG) still exists.
In the current study, we present our case lood in treating patients with concomitant carotid artery stenosis and coronary artery disease.
Patients and Methods: CABG with additional CEA due to neurologic symptoms or high grade (>80%) CAS has been performed in 835 patients in the period of 1982-2010. Results of evaluation of perioperative mortality and morbidity in regard to the surgical approach have been discussed.
Results: The average patient age was 62.6 ± 8.7 years. Echocardiography revealed that 28% of the patients had poor left ventricle ejection fraction (60%). In terms of neurological status, majority of the patients (88.3%) were neurologically asymptomatic. The overall mortality regardless the sequence of procedures was 2.3% (19 patients). In the group of concomitantly treated patients 44.6% (50 patients) required triple coronary bypass while the mean number of coronary bypasses was 2.6. Postoperative neurologic complications were present in 102 patients (12.2%). Eighty-four patients (10.0%) have had TIA, while 18 patients (2.2%) have had permanent neurologic deficit while 4 patients (0.5%) died as a result of it.
Conclusions: It is imperative that every patient being considered for CABG should undergo ultrasonic evaluation of the carotid arteries regardless the neurological symptomatology. Concomitant surgery on patients with severe CAS and coronary disease carries a slightly higher operative risk and, therefore, should be avoided. Concomitant surgical treatment should only be considered in patients with unstable angina and significant CAS in whom we may expect higher morbidity and mortality.
