Strategy of CABG for patients with diffusely diseased left anterior descending coronary artery

Abstract

Objecives: The aim of this study was to assess the strategy of coronary artery bypass grafting (CABG) for diffusely diseased left anterior descending coronary artery (LAD). Methods: We retrospectively reviewed 59 patients undergoing CABG in the diffusely diseased LAD between September 1995 and March 2014. Of these, 47 patients underwent multiple grafting (group M) and 12 patients underwent onlay patch grafting (group O). We compared and analyzed two groups. Results: The mean number of distal anastomosis was 4.8 and 4.3 in the groups M and O, respectively. The operation time was longer and the prevalence of reoperation for bleeding and postoperative stroke was significantly higher in the group O. The early operative mortality rate was zero in both groups. The probability of freedom from cardiac death, cardiac events, long-term graft patency rate was similar and excellent in both groups. Conclusions: The revascularization of LAD extensively using multiple grafting or onlay patch grafting showed excellent early and long-term outcomes.
