Background: The surgical options for diffuse coronary artery disease (CAD) are still controversial, especially in patients with advanced atherosclerotic disease. Coronary endarterectomy (CE) as an adjuvant to coronary artery bypass graft (CABG) has a successful role in the recovery of these patients; however, postoperative and long term outcome and complications restrict its usage when compared with CABG alone. This study was designed to compare peri and postoperative outcomes of patients undergoing CABG with CE and CABG alone.

Material and Methods: In this observational study, retrospective data collection was done from September 2010 to 2018. A total of 200 patients who underwent CABG were included and divided into two groups: group A patients underwent CABG, and group B patients underwent CABG with coronary endarterectomy. Patients were managed by a single surgeon at various public and private healthcare settings. Adult patients of both genders were studied. Patients with a history of previous bypass grafting were excluded. The study outcomes were postoperative morbidity, such as myocardial infarction (MI), reexploration, and mortality.

Result: Age and gender of patients were comparable between the two groups, with male dominance. Postoperative MI, re-exploration, respiratory failure, stroke, and mediastenitis were slightly greater in the CABG with CE group. Two (2.0%) patients died in the CABG group and 3 (3.0%) in the CABG with CE group. Hospital stay was significantly longer in the CABG with CE group (7.8 versus 7.0 days; p-value, 0.008). Similarly, the stay in intensive care was also significantly longer in the CABG+ CE group (3.5 versus 2.4 days; p-value: 0.001). CONCLUSION: Coronary endarterectomy may be a feasible method for adequate and complete revascularization of complex and diffuse coronary artery disease in patients undergoing CABG.
