title: External-internal oblique reverse blood supply musculocutaneous flap for chest wall reconstruction.
abstract: A defect resulting from resection of advanced breast tumor can be quite large, posing a difficult reconstructive challenge. A significant number of such patients are found to have local recurrences after receiving beam radiation therapy and chemotherapy. The external oblique musculocutaneous flap is now considered a reliable option, with segmental blood supply from the posterior intercostal arteries. We report a 57-year-old man with local recurrence of breast tumor after external beam therapy. We faced a difficult challenge in performing reconstruction because of (1) several previous operations that used most of the usual options and (2) the absence of recipient vessels for microsurgery. We performed an external-internal oblique musculocutaneous flap with a reverse blood supply from the lateral branches of the inferior epigastric artery. Our use of a reverse-flow external-internal oblique flap supports the concept of rotating the muscles as a unit to encourage viability of the denervated and relatively devascularized component.
