The use of the serratus anterior muscle vascular pedicle as recipient site in DIEP flap transfer for breast reconstruction.

Abstract

Currently, the choice for recipient vessels in microvascular breast reconstruction is made between axillary and internal mammary regions. The authors report their experience with anastomosis to a new, unconventional, axillary recipient vessel, the serratus anterior muscle vascular pedicle. Among 340 deep inferior epigastric perforator (DIEP) flap breast reconstructions performed between 2004 and 2013, 11 were successfully revascularised to the serratus anterior (SA) pedicle: In three cases, complications led to a salvage procedure, while in eight cases, anastomosis to this recipient site was electively planned. The pedicle was constantly present, with calibre always comparable to that of flap's pedicle. At the mean 24-month follow-up, no recipient site complications were observed. The SA muscle pedicle resulted as a reliable choice in salvage procedures and a suitable option for recipient vessel selection in elective cases.
