[Obstructive Colon Cancer with Triple-Vessel Coronary Artery Disease - A Case Report].

The patient was a 70-year-old woman who was diagnosed with obstructive transverse colon cancer suspected of invading the abdominal wall by abdominal CT imaging. Since the preoperative electrocardiogram showed an ischemic change, echocardiography and coronary angiography were performed. We diagnosed chronic heart failure and angina pectoris because echocardiography showed low cardiac function(left ventricular ejection fraction; LVEF 37%)and coronary angiography indicated triple-vessel disease. We firstly performed coronary artery bypass graft surgery following self-expanding metallic stent placement as a bridge to surgery(BTS), because we judged this patient as a perioperative high-risk case. After improvement of cardiac function(LVEF 49%), expanded right hemicolectomy with partial resection of abdominal wall could be performed without perioperative complications. Colonic stenting as a BTS allowed us to treat comorbidities properly, and perform a radical surgery safely for such a high-risk patient.
