Plexus between Internal Mammary Graft and Pulmonary Vasculature after Minimally Invasive Coronary Surgery

We report a complication associated with minimally invasive direct coronary artery bypass grafting surgery. The patient suffered a nonfatal anterior myocardial infarction 1 day after he underwent minimally invasive bypass grafting using the internal mammary artery. Two months later, coronary arteriography revealed a fistulous connection between the left internal mammary graft and the left pulmonary vasculature. To our knowledge, this particular complication has not been reported following minimally invasive coronary surgery.
