Minimally Invasive Multiple Coronary Artery Bypass Grafting with Composite Graft Using in situ Right Gastroepiploic and Radial Arteries

Minimally invasive surgery/coronary artery bypass grafting (MICS CABG) via left thoracotomy and multiple CABG is a reported alternative to the standard sternotomy approach. However, harvesting the right internal thoracic artery (RITA) under direct vision requires high surgical skill. We describe MICS CABG with the left internal thoracic artery (LITA) and a composite graft using the in situ right gastroepiploic artery (GEA) and radial artery (RA) to achieve complete coronary revascularization. No complications occurred, and postoperative computed tomography showed patency of all grafts. Our experience suggests that this composite graft can be used safely and effectively in MICS CABG for complete arterial revascularization without difficulty.
