Abstract

Thigh-based flaps are increasingly popular options for autologous breast reconstruction in the setting of abdominal donor-site inadequacy, previous surgery, or patient preference, but the volume and skin associated with these flaps are often lacking relative to the abdomen. An individualized, shared decision-making approach to donor-site selection was adopted based on body shape, surgical history, lifestyle, reconstructive needs, and patient expectations. Different thigh-based flaps combined in stacked, bipedicled, or conjoined configurations were selected to maximize efficient use of available soft-tissue skin and volume while optimizing donor-site aesthetics. A total of 23 thigh-based stacked, bipedicled, or conjoined profunda artery perforator (PAP), lateral thigh perforator (LTP), or gracilis musculocutaneous flap components were used in six patients. Configurations included bilateral stacked PAP and LTP flaps, bipedicled posterolateral thigh flaps based on the LTP and PAP (L-PAP), and bipedicled thigh flaps based on the gracilis and PAP pedicles. Most anastomoses were performed to the antegrade and retrograde internal mammary vessels; intraflap anastomoses were performed in one case. There were no partial or total flap losses. There was one donor-site seroma. Design of stacked, bipedicled, and conjoined thigh-based flaps using multiple conventional flap components allows for tailored approaches to donor-site utilization based on individual body shape in selected patients. Bipedicled design with the L-PAP flap represents one strategy in appropriate cases to overcome skin and volume deficiencies while facilitating coning and projection.
