The reinforced pedicle technique: a case report of secondary mastopexy following nipple-sparing mastectomy with autologous breast reconstruction.

Abstract

Immediate autologous reconstruction after nipple-sparing mastectomy (NSM) is challenging in the ptotic breast due to the large skin envelope and reduced vascular supply to the nipple areolar complex (NAC). Patients with significant ptosis who want to preserve their NACs are often advised to undergo a two-stage procedure: first, a mammoplasty is performed to lift the NAC, and second, a delayed NSM with autologous reconstruction is performed. Unfortunately, patients with active cancer cannot delay their mastectomy; as such, they are often treated with skin-sparing mastectomy (SSM) instead. The reinforced pedicle is an innovative technique that allows the NAC to be safely raised after NSM with immediate free flap reconstruction. In the first stage, patients with ptotic breasts undergo NSM and immediate autologous reconstruction. The reconstruction itself also appears ptotic, but the dermal blood supply to the NAC is preserved. In the second stage, the ptotic free flap reconstruction is revised using the reinforced pedicle technique, which allows the flap to be reduced and the nipple raised in the manner of a standard superior pedicle breast reduction. Using this technique, we have successfully raised a patient's NAC by 2.5 cm. The reinforced pedicle technique adds to the scant literature on secondary revision techniques after autologous breast reconstruction. While further research on this technique is needed, it has the potential to alter the paradigm of immediate autologous reconstruction in the ptotic breast, allowing such patients to preserve their native NACs.
