Report of simultaneous off-pump CABG and modified mastectomy.

The patient was a 75-year-old female who had received medical treatment for effort angina. Recently, she noticed a left breast tumor, which was diagnosed as breast cancer with axillary lymph node swelling. Coronary angiography performed prior to the surgery for the breast cancer showed 90% stenosis in segment 6 of the left anterior descending artery (LAD). Coronary intervention was not possible due to anatomical reasons, so she was admitted for simultaneous surgery for the breast cancer and angina. The chest was opened through a median sternotomy and the full-skeletonized right internal thoracic artery was grafted on the LAD without cardiopulmonary bypass. A transverse elliptical incision was made after the median sternotomy was closed, and the breast tumor and lymph nodes around the subclavian and axillary vessels were completely dissected. Even in the case of multiple vessel coronary disease, simultaneous surgery may be possible, but indications should be carefully assessed considering the cardiac function and general condition of the patient.
