title: Chest wall reconstruction of severe mediastinitis with intercostal artery-based pedicled vertical rectus abdominis muscle flap with oblique-designed skin pedicle.
abstract: Recurrent poststernotomy mediastinitis has significant morbidity and mortality. Reconstructive treatment begins with pectoral muscle or omental flaps. When these options are unavailable or inadequate, surgeons resort to internal mammary artery-based vertical rectus abdominis muscle flap. If the internal mammary artery is harvested for coronary artery bypass grafting, surgeons are reluctant to use the muscle for pedicled flap because of the elevated risks. However, recent reports suggest that if enough time passes for intercostal artery collaterals to develop, they would support the viability of the flap. Moreover, recent improvements in defining flap microvasculature and proposed surgical techniques have enabled us to further refine the procedure. Although it appears that the intercostal artery-based pedicled vertical rectus abdominis muscle flap with oblique-designed skin pedicle is safe and effective for chest wall reconstruction, potential for failure remains elevated until sample size accumulates.
