Double-pedicle transverse rectus abdominis myocutaneous flap for unilateral breast and chest-wall reconstruction.

Fifteen patients underwent unilateral breast and chest-wall reconstruction by a double-pedicle transverse rectus abdominis myocutaneous flap technique. Criteria for using both pedicles include (1) exceptionally large soft-tissue requirements, (2) prior abdominal operations compromising the vasculature to portions of the anterior abdominal wall, and (3) certain higher-risk patients with suspected microvascular pathology. Double pedicles allowed the transfer of the skin island as one unit or as two independent hemiellipses of tissue. Follow-up time ranges from 4 to 17 months. Complications included partial tissue loss in two patients, one abdominal flap seroma, and one patient with a hernia.
