Objective To evaluate the effectiveness of anterolateral thigh polyfoliate perforator flap plus pedicle with one foliate flap for repairing extremities soft tissue defect. Methods Between January 2014 and January 2017, 24 patients with extremities soft tissue defects were treated by anterolateral thigh polyfoliate perforator flap plus pedicle with one foliate flap. There were 15 males and 9 females, with a median age of 33.5 years (range, 5-64 years). Wounds located in upper limb in 8 cases, complicated with radial styloid fracture in 1 case, extensor tendon exposure in 3 cases, and brachioradialis muscle tendon exposed in 1 case. Wounds located in lower extremity in 16 cases, complicated with calcaneal or metatarsal, phalangeal fractures in 4 cases, Achilles tendon departure in 1 case, toe long extensor tendon and flexor digitorum longus tendon exposed in 8 cases. The wound area ranged from 8 cm×5 cm to 18 cm×12 cm. According to wound size, anterolateral thigh perforators were detected by conventional ultrasound Doppler (2-5 perforators). The irregular wounds were decomposed into multiple parts and the leaf number (2-4 leaves) of polyfoliate flap depended on the part number of the wound. The flap area ranged from 9 cm×6 cm to 20 cm×14 cm, and the largest area of single leaf was 24 cm×6 cm. The vascular pedicle length ranged from 7 cm to 12 cm. The foliate flap area with protecting pedicle ranged from 5 cm×3 cm to 7 cm×5 cm. Results All the flaps survived, and no vascular crisis occurred. All the patients were followed up 2-28 months (mean, 9 months). Sinus occurred in 1 case of calcaneal fracture after flap repair, and the sinus was healed after 3 months by conventional dressing. All the flaps were thin and had a good texture. Healing of soft tissue was found in 5 patients with fracture. The wrist and ankle plantar flexion and dorsiflexion function of recipient site were normal in all patients. Conclusion It is safe and reliable to repair the extremities soft tissue defect with anterolateral thigh polyfoliate perforator flap plus pedicle with one foliate flap. And it is one of the ways to reduce the vascular crisis of the anterolateral thigh free perforator flap.
