    Abstract:
    BACKGROUND: Little is known about the graft patency after coronary endarterectomy (CE) combined with coronary artery bypass grafting (CABG). This study aimed to investigate the graft patency after CABG + CE. METHODS: Eligible patients hospitalized at our center during September 2008 and July 2022 with complete follow-up coronary angiographic data available were retrospectively enrolled. The primary end point was the follow-up graft patency of CE targets. Logistic regression was performed to explore the potential predictors of the CE-targeted graft failure. RESULTS: A total of 160 patients (age: 59.4 ± 9.3 years, male: 75.6%) were enrolled, and 560 grafts were anastomosed. CE was performed on 166 sites, including LAD (36.1%), right coronary artery (RCA, 48.2%), left circumflex artery (9.6%), and diagonal branches (6.0%). Postoperative myocardial infarction was observed in 7 (4.4%) of the patients. During a median follow-up of 12.1 months, the CE-targeted graft patency was 69.9%. The CE-targeted graft patency rate was much higher among the LAD-CE patients than the non-LAD-CE patients (80.0% vs. 64.2%, P = 0.032) but lower than non-endarterectomized LAD (80.0% vs. 92.9%, P = 0.013). No difference was observed regarding the graft patency between off-pump and on-pump surgery (P = 0.585). In the logistic regression, RCA-CE was associated with an increased risk of graft failure even after multiple adjustments (odds ratio: 2.35, 95% confidence interval: 1.05-5.28, P = 0.028). CONCLUSIONS: CABG + CE might be associated with decreased graft patency, especially in those who received RCA-CE, irrespective of surgical technique or antiplatelet/anticoagulation regimen. A multi-center prospective, possibly randomized study with a larger sample size is warranted.
