title: Fatal ischemia of bowel and rectus abdominal muscle after off pump coronary artery bypass grafting in a dialysis patient.
abstract: We have experienced a case which developed mesenteric ischemia followed by necrosis of the rectus abdominal muscle after off pump coronary artery bypass grafting (OPCAB). A 62-year-old man with a history of long-term hemodialysis was diagnosed with left main trunk disease. He underwent triple OPCAB uneventfully. No inotropic agents were needed perioperatively. He underwent normal hemodialysis on the first postoperative day, and then complained of severe abdominal pain with progressive metabolic acidosis. A 170 cm length of the ileocecal segment fell into necrosis and was excised and an ileostomy was constructed in an emergency setting. He developed another abdominal pain 6 days after the second operation. An additional surgery confirmed necrosis of the right rectus abdominal muscle complicated with a significant infection. He developed mediastinitis and died of multi-system organ failure 37 days after OPCAB. The mechanism of this serious complication is discussed.
