Aim: In this study, we aimed to investigate the effect of the single aortic cross-clamp technique (SCT) (aortic cross-clamp only) versus the multiple-clamp technique (MCT) (aortic cross-clamp + side-biting clamp) on postoperative stroke in octogenarians undergoing coronary artery bypass grafting (CABG).
Methods: A total of 171 patients aged 80 years and older who underwent isolated CABG were retrospectively analysed. The patients were divided into two groups according to the technique used during surgery: group 1 (n = 88) received the SCT, and group 2 (n = 83) received the MCT. Postoperative stroke was evaluated.
Results: Of the patients, 127 were men and 44 were women. The mean age was 83.05 ± 8.81 years in group 1 and 82.14 ± 8.92 years in group 2. There was no statistically significant difference in the rate of postoperative stroke between the two techniques (p > 0.05).
Conclusions: Postoperative stroke in octogenarians may result from not only the cross-clamp technique used but also several other factors. We found that both techniques yielded similar outcomes.
