A fifty seven-year-old man visited the outpatient department with chest pain and claudication. Coronary angiogram showed coronary artery diseases (3-vessel diseases) and CABG was planned. However, lower extremity angiogram showed stenosis of both common iliac arteries and stent implantation of both iliac arteries were done before CABG. He underwent CABG and IABP was inserted for weaning from cardiopulmonary bypass. After CABG, ischemic change on ends of feet was noted with red-brown colored urine and hyperkalemia. Blood myoglobin level was over 3,000 ng/ml. Microembolism of his lower body was revealed by multiple uptakes on the whole body bone scan study. After management by massive hydration and alkalization of urine with sodium bicarbonate, he was recovered without renal replacement therapy and discharged in good condition.
