Abstract
The complete survival of a teres major--latissimus dorsi skin-muscle flap for chest reconstruction is reported in a patient in whom the primary neurovascular pedicle of the latissimus muscle had previously been sacrificed. At operation, collateral vessels of 1-mm proportions were noted to have developed between the innervated teres major and denervated latissimus dorsi muscle. In this case, the teres major muscle rotated with the latissimus muscle to affect reconstruction of a full-thickness anterior chest resection. This report suggests the possibility of a denervated, relatively devascularized muscle obtaining additional blood supply from adjacent innervated vascularized muscles and supports the concept of rotating the muscles as a unit to encourage viability of the denervated component.
