A case report of gastric perforation after coronary artery bypass grafting with right gastroepiploic artery

A 71-year-old man, who had received coronary angioplasty to right coronary artery 1 year before, was admitted because of unstable angina. An urgent CABG was performed using the left internal thoracic artery and the right gastroepiploic artery. Coronary anastomosis was performed under ventricular fibrillation due to porcelain aorta. Seven days after surgery, abdominal pain was suddenly experienced. A chest X-P showed subphrenic free air. So an emergent laparotomy was performed, and a 2 × 2 cm gastric perforation was found on the anterior wall of the greater gastric curvature. Partial gastrectomy was performed. However, he unfortunately died on the 58th postoperative day for multiple organ failure. Pathological examination of the excised gastric wall revealed ischemic change, not ulcer. This gastric perforation was possibly caused by ischemia after harvesting the right gastroepiploic artery.
