Abstract

Background: In procedures involving surgical maneuvers such as cannulation, clamping, or proximal anastomosis where aortic manipulation is inevitable, a preliminary assessment of the atherosclerotic plaques bears clinical significance. In the present study our aim was to evaluate the frequency, and distribution of the aortic calcifications in patients undergoing coronary artery bypass grafting (CABG) surgery in order to propose a morphological classification.

Methods: A total of 443 consecutive patients with coronary artery disease were included in the study. Preoperative non-contrast enhanced computed tomography images, in-hospital follow up data and patient characteristics were retrospectively evaluated.

Results: While 33% of the study participants had no calcification at any site in the aorta, 7.86%, 75.4%, and 16.67% of the remaining patients had calcification in ascending aorta, aortic arch, and descending aorta, respectively. Focal small calcifications were the most common type of lesions in the ascending aorta (3.93%), while 9 patients (1.41%) had porcelain ascending aorta. A total of 4 types with increasing severity and extent of calcification (i.e. 1 denoting the least severe and 4 denoting the most severe calcification) were defined.

Conclusions: According to the frequency and distribution of calcification in the thoracic aorta, a classification system stratifying patients from the least to most severe was proposed to be used for coronary artery disease patients who are candidates for CABG.
