Posttraumatic upper extremity wound coverage utilizing the extended deep inferior epigastric flap.

The extended deep inferior epigastric artery (DIEA) flap was used in 4 patients with traumatic mid upper extremity wounds. Although there are numerous flaps available for resurfacing upper extremity defects, including the groin, thoracoepigastric, and a host of microvascular flaps, in each of these patients a preoperative consideration necessitated a novel approach. The DIEA flap is based on an axial vascular watershed resulting in a long, thin, well-vascularized, supple skin flap, which proved extremely effective in solving the reconstructive needs of these patients. The flap is technically simple to elevate and quite versatile. In all patients, the flaps survived and healing of the wounds was achieved. The DIEA flap should be considered a valuable reconstructive alternative when faced with elbow and forearm defects.
