Multi-Flap Microsurgical Autologous Breast Reconstruction

Microsurgical autologous breast reconstruction (MABR) remains the gold standard technique of breast reconstruction, providing a durable, natural, and aesthetically pleasing result. However, some patients may not be candidates for a traditional deep inferior epigastric perforator (DIEP) flap, either due to abdominal tissue paucity, the need for higher-volume reconstruction, or prior surgical procedures. In these patients, alternative flaps must be considered to achieve the optimal result. Such configurations include the conjoined (or double pedicle) DIEP flap, and alternative flaps such as the lumbar artery perforator (LAP) and profunda artery perforator (PAP) flaps, which can be combined in a stacked fashion. By combining multiple flaps in a conjoined or stacked fashion, breast reconstruction can be optimized to fulfill the three critical components of breast reconstruction in restoring the skin envelope, breast footprint, and conus shape. When harvesting multiple flaps, the surgical sequence of events must be meticulously planned to ensure an efficient and successful operation. Preoperative imaging can aid the surgeon in identifying the ideal perforator, assess for side branches for possible intra-flap anastomoses, expedite the operative time, and decrease intraoperative complications. Reconstructive surgeons should be familiar with the variety of configurations with conjoined and/or stacked flaps to address patient-specific reconstructive needs.
