The lateral thigh perforator (LTP) flap for autologous breast reconstruction: A prospective analysis of 138 flaps.

Background: The septocutaneous tensor fasciae latae (sc-TFL) or lateral thigh perforator (LTP) flap was previously introduced by our group as an alternative flap for autologous breast reconstruction when the abdomen is not suitable as a donor site. The aim of this study was to analyze our experience with the LTP flap and to present the surgical refinements that were introduced. Methods: A prospective study was conducted of all LTP flap breast reconstructions performed since September 2012. Patient demographics, operative details, complications and flap re-explorations were recorded. Preoperative imaging with MRA was performed in all patients. Surgical refinements that were introduced during this study included limitation of the flap width and the use of quilting sutures at the donor site. Results: A total of 138 LTP flap breast reconstructions were performed in 86 consecutive patients. Median operation times were 277 minutes (range 196-561) for unilateral and 451 minutes (range 335-710) for bilateral procedures. Median flap weight was 348 grams (range 175-814). Two total flap losses (1.4%) were recorded and eleven flaps (8.0%) required re-exploration, which resulted in viable flaps. The incidence of donor-site complications reduced significantly after the surgical refinements were introduced. Wound problems decreased from 40.0% to 6.3%, seroma from 25.0% to 9.5%, and infection from 27.5% to 9.5%, respectively. Conclusions: The LTP flap is an excellent option for autologous breast reconstruction with minimal recipient-site complications. The surgical refinements resulted in a significant reduction of donor-site complications. Therefore, the LTP flap is currently our second choice after the DIEP flap.
