Abstract

Background The posterior thigh-based profunda artery perforator (PAP) flap has been an emerging option as a secondary choice in breast reconstructions. However, whether a PAP flap could consistently serve as the secondary option in slim patients has not been investigated.

Methods Records of immediate unilateral breast reconstructions performed from May 2017 to June 2019 were reviewed. PAP flap breast reconstructions were compared with standard deep inferior epigastric perforator (DIEP) flap breast reconstructions, and were grouped into single or stacked PAP flaps for further analysis.

Results Overall, 43 PAP flaps were performed to reconstruct 32 breasts. Eleven patients underwent stacked PAP flap reconstruction, while 17 patients underwent 21 single PAP flap reconstruction. The average body mass index (BMI) of the patients was 22.2 ± 0.5 kg/m2. The results were as follows: no total loss, one case of venous congestion (2.3%), two donor site wound dehiscence cases (4.7%), and one case of fat necrosis from partial flap loss (2.3%). When compared with 192 DIEP flap reconstructions, the final DIEP flap supplied 98.1 ± 1.7% of mastectomy weight, while the final PAP flap supplied 114.1 ± 6.2% of mastectomy weight (p < 0.005), demonstrating that PAP flaps can successfully supply final reconstruction volume. In a separate analysis, single PAP flaps successfully supplied 104.2% (84.2-144.4%) of mastectomy weights, while stacked PAP flaps supplied 103.7% (98.8-115.2%) of mastectomy weights.

Conclusion In our series of PAP flap reconstructions performed in low-to-normal BMI patients, we found that PAP flaps, as single or stacked flaps, provide sufficient volume to reconstruct mastectomy defects.
