Clinical Application and the Free Posterior Thigh Perforator Flap

The posterior thigh flap based on the third perforating artery of the PFA is an excellent option for reconstructing soft tissue defects. The anatomical location of the third perforating artery is relatively consistent. The vascular pedicle is relatively longer and has large caliber vessels. The scar at the donor site can be well concealed with low morbidity. The skin color and texture of this flap show satisfactory results.
