A 75 year-old male patient underwent coronary artery bypass surgery (LITA-LAD#7, RITA-RCA#2 and SVG-PL) for myocardial infarction on February, 2002. His intraoperative and postoperative conditions were good through follow up in the outpatient clinic. He was admitted for sudden hemoptysis on August, 2006. The hemoptysis halted by hemostatic agents. Chest X-ray and CT demonstrated no abnormal findings. However, angiography showed marked dilatation, tortuosity and flexure in the left bronchial artery and pericardial branch of the left internal thoracic artery, as well as hemangioma in the left B1+2a region. We diagnosed this as racemose hemangioma of the bronchial artery. We transferred him to a different hospital where arterial embolization was performed in the left bronchial artery and pericardial branch of the left internal thoracic artery. He developed myocardial infarction after surgery and IABP was necessary. Thereafter his condition was stabilized.
