The anatomic basis of the profunda femoris artery perforator flap: a new option for autologous breast reconstruction--a cadaveric and computer tomography angiogram study.

Overview

We propose the profunda femoris artery perforator (PAP) flap for autologous breast reconstruction. We provide an anatomic basis for this flap. Ten cadaveric thighs were dissected. A perforator was dissected to its origin. The lengths of pedicle, vessel diameters, and weights were measured. The average distance inferior to the gluteal crease was 3.5 cm (1 to 5 cm). The average distance from the midline was 6.2 cm (3 to 12 cm). The average pedicle length was 10.6 cm. Diameters of the artery and vein averaged 2.3 mm and 2.8 mm. The flaps averaged 28 × 8 cm. The average weight was 206 g (100 to 260 g). Computed tomography angiograms of 20 thighs were examined. Measurements were taken from the gluteal crease and midline to the perforator. The average distance caudal to the gluteal crease was 4.4 cm (1.1 to 7.2 cm). The average distance lateral to the midline was 5.1 cm (2.5 to 9 cm). The data presented in this article provide an anatomic basis for the PAP flap.
