[Minimally invasive coronary artery bypass (MIDCAB) for double vessel using Y arterial graft which consists of left internal thoracic artery and right inferior epigastric artery].

MIDCAB is a rapidly evolving technique to revascularize the left anterior descending coronary artery (LAD) with the left internal thoracic artery (LITA). Our case is a 60-year-old female with unstable angina due to restenosis of the proximal LAD following PTCA and proximal stenosis of the large first diagonal branch (D1). She underwent double vessel MIDCAB (LITA-LAD and LITA-RIEA-D1) using Y composite arterial conduit with LITA and right epigastric artery (RIEA), because of chronic renal failure on maintenance hemodialysis. Postoperative course was uneventful and postoperative angiography revealed a patent Y graft. Y graft using IEA appears to be an interesting operative method in double vessel MIDCAB.
