Abstract

Background

Occasionally, the deep inferior epigastric perforator flap is unavailable for autologous breast reconstruction. Alternative options, such as gluteal artery perforator flaps, the transverse upper gracilis flap, and the profunda artery perforator (PAP) flap, have been well documented. In our initial experience, the PAP flap was associated with limitations at the donor site. Therefore, a geometrically modified PAP flap was evaluated.

Methods

Forty geometrically modified PAP flap reconstructions were performed on 30 patients. Our modification comprised flap harvest from a more cranial area, hereby adding abundant inferior gluteal tissue to the flap while sparing superior thigh tissue. Patient characteristics, anatomical variables, and clinical outcome were prospectively evaluated.

Results

Mean patient age was 44 years, and mean body mass index (BMI) was 23.3 kg/m2. Mean flap size was 32 × 12 cm, and mean weight was 385 g. Mean number of suitable perforators (diameter ≥ 0.5 mm) in the adductor magnus area was 1.7 per thigh. All flaps survived completely. Wound dehiscence at the donor site occurred after 4 unilateral reconstructions. Transient lymphedema of the leg occurred after 4 other unilateral reconstructions. Other wound morbidity or systemic complications did not occur. Secondary breast surgery for symmetry and volume was indicated after 16 reconstructions. Preoperative bra size was unchanged or larger in 36 reconstructions. Scar position in the crease was achieved after 39 reconstructions. Sensibility changes of the posteromedial thigh region were not observed.

Conclusions

The geometrically modified PAP flap ensures in-the-crease scar positioning and provides sufficient tissue to restore preoperative bra size.
