First case report of bilateral breast necrosis following coronary artery bypass graft using left internal mammary artery.

Coronary artery bypass grafting (CABG) using internal mammary artery is a frequently performed procedure for the treatment of coronary artery disease nowadays. Ipsilateral breast necrosis is a rare and seldom reported complication that may mimic breast cancer on presentation. However, contralateral breast necrosis has not been reported to date. We are reporting the first case of bilateral breast necrosis after CABG using the left internal mammary artery. We discuss the different underlying mechanisms and possible co-factors behind the development of this rare complication, and we also share a successful management approach to conserve the breast and improve the patient's outcome.
