[One-stage coronary artery bypass and extra-anatomical bypass operation in a patient with ischemic heart disease and Leriche syndrome; report of a case].

With the overall increase in ischemic heart disease (IHD), cases combining arteriosus sclerosis obliterans (ASO) of the lower extremity and IHD are on the rise. Each case is unique and requires the use of various criteria to select between methods of operating. This case involves IHD with low cardiac function, conbined with ASO of the collateral circulation fed to the legs through the internal thoracic artery and a calcified abdominal aorta refractory to anatomical reconstruction. We selected a one-stage operation of axillo-bifemoral bypass grafting and coronary artery bypass grafting. The postoperative course was uneventful, and the patient was discharged on the 23rd day after operation.
