Abstract :Aim: Coronary artery bypass surgery of the primary conduits employed in coronary artery bypass grafting surgery (CABG) is the left internal mammary artery (LIMA), which has garnered considerable attention due to its favorable characteristics and outcomes. There are not enough studies examining the relationship between benign breast diseases (BBD) and LIMA removal. This study is one of the pioneering studies investigating the effects of LIMA removal after bypass surgery in patients with benign breast diseases. This study aims to evaluate the effect of LIMA removal on benign breast diseases in female patients undergoing bypass surgery by analyzing pre- and post-operative breast imaging. Material and Methods: A total of 47 of 452 female patients who underwent bypass surgery between February 18, 2019, and December 31, 2021, were included in the study. All patients’ LIMA were harvested and evaluated, regarding any progression of benign breast diseases. Results: There was a significant difference between the Breast Imaging Reporting and Data System (BI-RADS) classes of the patients before and after CABG (p<0.001). While 40.4% of the patients were BI-RADS class 1 preoperatively, this rate decreased to 14.8% postoperatively. Class 2 level did not show a significant difference, while class 3 level increased from 8.5% to 31.9%. Correlation analysis results between pre-op and post-op BI-RADS classes and age and Body Mass Index (BMI) were analyzed, but no significant correlation value was found. The correlations between pre-op and post-op BI-RADS grades and Hormone Replacement Therapy (HRT) were significant. Conclusion: It can be concluded that LIMA harvesting during CABG surgery in female patients affects the occurrence of BBD. The change between the pre-op and post-op period was determined by mammography tests. It was shown that there was a significant change in BI-RADS scores on mammography after bypass surgery.
