The effect of the number of vessel grafts used in coronary artery bypass grafting surgery to short-term mortality

Abstract

Purpose: The study aimed to share the short-term mortality rates of coronary artery bypass grafting (CABG) experience in a private hospital and to evaluate parameters affecting the clinical outputs following the CABG who were divided according to the number of vessel graft.
 Materials and Methods: The study is a longitudinal-term observational clinical study, with a patient follow-up period of 7 years in Turkey. We analyzed 3027 cases with outcomes and short-term mortality according to the number of vessel grafts that we used as 1 (n:608), 2-3 (n:1359), and four or more (n:1060) grafts.
 Results: The short-term mortality was found as 1.1% (36/3027) in all the patients. The male population was the highest in the group with the highest number of vascular grafts and its percentage to females was correlated with vessel grafts that we performed. Mean aortic cross-clamp time was 36.6±17.2 minutes, while bypass time was 66.4±21 minutes. The mean number of vessels revascularized was 3.17±0.9 (1-7). The amount of drainage was 419±286 ml. The period of intensive care was 1.2±1.1 days, while the hospital period was 5.2±1.5days. In comparison according to the number of vascular grafts, positive inotrope agent, drainage, blood supply, cross-clamp and pump period showed significant difference.
 Conclusion: The number of vessel grafts was related to clinical outputs of CABG operations and Our CABG in the private hospital reached the short-term mortality rates that were below the averages of Turkey and international operations.
