摘要
Background: With increasing incidence of coronary artery disease (CAD) in Saudi Arabia and its fatal co-morbidity, this has resulted in a more complex pool of cases referred to cardiac surgeons. In selected cases, achieving optimal revascularization of diffuse CAD necessitates adjunctive techniques such as coronary endarterectomy (CE). The aim of our study is to evaluate the early mortality and post-operative morbidity related to CE. Method: Retrospective study from Jan 2009 to Dec 2010. Inclusion of 186 patients: 38 patients had CABG with CE and 148 patients had CABG alone. Results: Pre-operative percutaneous coronary intervention (PCI) was higher in the CE with CABG group (25.8%) compared with CABG alone (8.9%) (p = 0.009). Intra-operative data showed a higher mean cardiopulmonary bypass time (CBT) of 160 minutes and a mean cross-clamp time (XCT) of 109 minutes in the CE with CABG, compared to a mean CBT of 129 minutes and a mean XCT of 87 minutes in the CABG alone group (p = 0.001). The most common vessel endarterectomized was left anterior descending artery (LAD) (47%) followed by right coronary artery (RCA) (22%). Post-operatively, the mortality amongst the CE with CABG group (7.9%) was higher than CABG only group (1.4%), however it wasn’t statistically significant (p = 0.06). With regards to morbidity, hemodynamic instability requiring intra aortic balloon pump (HIR-IABP) was higher in the CE with CABG group (10.5%) compared to the CABG only group (1.4%) (p = 0.018). Conclusion: Our study showed that CE when combined with CABG wasn’t associated with a higher mortality rate when compared with CABG alone.
