Partial breast necrosis after MIDCABG via small anterolateral thoracotomy.

We report a case in which partial breast necrosis developed after minimally invasive direct coronary artery bypass grafting using an IMA Retractor (Cardio-Thoracic Systems Inc, Cupertino, CA). We suggest that during minimally invasive direct coronary artery bypass grafting in the presence of a large breast, it is advisable to reduce the intraoperative additive forces of pressure and traction caused by the retractor arm on the breast tissue, thus avoiding further excessive compression on the partially compromised blood circulation of the breast.
