A 79-year-old woman with angina pectoris was admitted to our institution. Coronary angiography revealed triple vessel disease. The patient had giant gastric varices 30mm in diameter and also had liver cirrhosis (Child-Pugh classification grade A). To prevent perioperative bleeding complications, we selected and performed off-pump coronary artery bypass grafting (RITA-LAD#8, LITA-LCx#14, Ao-RA-#4AV). She was discharged on the 12th postoperative day without any complications.
