A 40-year-old man was admitted because of coronary heart disease with a totally calcified ascending aorta and Leriche's syndrome. Establishing a cardiopulmonary bypass seemed to be difficult because neither the ascending aorta nor femoral artery was suitable as a cannulation site. It was not until a prosthetic conduit for revascularization of the lower extremities was anastomosed to the right axillary artery in preparation for the conversion from off-pump to on-pump that off-pump CABG was performed. Subsequently revascularization of the lower extremities was completed. The patient had a satisfactory postoperative course. Off-pump CABG is useful for patients with a severely calcified ascending aorta and occlusive lesions below the descending aorta.
