Less invasive direct coronary artery bypass grafting using H graft for a patient with advanced prostatic cancer.

Minimally invasive direct coronary artery bypass grafting (MIDCAB) using an H graft was performed on a 74-year-old man with advanced prostatic cancer who needed coronary revascularization. Through a left anterior small thoracotomy, the left internal thoracic artery (LITA) and the left anterior descending artery (LAD) were cleared, and a short radial artery (RA) was placed in an end-to-side fashion between the LITA and LAD. The distal LITA was ligated to avoid potential steal phenomenon. A flow pattern through the RA graft evaluated by transit time flow measurements demonstrated good diastolic flow with a mean value of 37 mL/min. The total surgical duration was 80 min, and no blood products were required. A postoperative angiogram showed a widely patent H graft. The patient was relieved of chest pain and was discharged. The H graft procedure is a useful alternative technique to minimize the surgical trauma in limited situations such as a high-risk case.
