  • REPAIR OF SOFT TISSUE DEFECT IN EXTREMITIES WITH ANTEROLATERAL THIGH PERFORATOR FLAP

    Objective To summarize the cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.

    Objective To improve the harvesting techniques of anterolateral thigh perforator flap, and to reduce the operation time. Methods Between January 2008 and June 2015, 400 patients undergoing repair with anterolateral thigh perforator flap were included to analyze the technical factors, including 370 cases (92.5%) obtaining primary healing and 30 cases (7.5%) receiving re-exploration. Combined with the literature, a modified flap dissection was made: reverse tracing and sequential dissection of the descending branch of the lateral circumflex femoral artery. Between June 2015 and June 2016, the modified free anterolateral thigh perforator flap was used in 100 cases. Of 100 cases, 76 were male and 24 were female, aged from 11 to 71 years (mean, 35.6 years). The wound size ranged from 8 cm×5 cm to 23 cm×9 cm. The time between injury and surgery ranged from 5 to 31 days (mean, 14.3 days). Results The operation time of modified flap dissection was reduced to (30.1±19.3) minutes from (85.0±30.2) minutes (unmodified flap dissection). Postoperatively, 94 flaps survived uneventfully, and incision healed by first intention. Six flaps received re-exploration surgery because of vascular compromise; the flap survived after removal of thrombosis in 4 cases of vein thrombosis; the flap necrosed in 2 cases of vein and artery thrombosis, and skin grafting was performed. Ninety-four patients whose flaps survived were followed up 3-12 months (mean, 6.3 months); the flaps had good color and appearance, and second stage operation was performed to make the flap thinner in 21 cases. Conclusion Improved harvesting technique of free anterolageral thigh perforator flap could decrease surgery time and difficulty in dissection.

    Objective To explore the feasibility of harvesting free thinned innervated anterolateral thigh (ALT) perforator flap for repairing the donor defect after wrap-around flap transfer. Methods Between May 2011 and December 2013, free thinned innervated ALT perforator flap was used to repair the donor defects after wrap-around flap transfer in 9 patients. There were 8 males and 1 female, with a mean age of 31.2 years (range, 19-42 years). The interval time between injury and admission was 3-12 hours (mean, 6.5 hours). Injury causes included machine crush injury (4 cases), traffic accident injury (3 cases), and twisting injury (2 cases). The wrap-around flaps were transferred to reconstruct thumb defects. And the size of donor site defect ranged from 3 cm×2 cm to 8 cm×5 cm. A branch of the lateral femoral cutaneous nerve was carried to make innervated ALT perforator flap for donor site repair. The size of innervated ALT perforator flap ranged from 3.0 cm×2.0 cm to 8.5 cm×5.0 cm. The thickness of innervated ALT perforator flap before defatting ranged from 2.0 to 4.5 cm (mean, 3.2 cm); the thickness after defatting ranged from 0.4 to 0.6 cm (mean, 0.5 cm). The defect at the anterolateral thigh was primarily closed in all cases. Results All reconstructed thumbs and ALT perforator flaps survived. All patients were followed up 6-30 months (mean, 15.8 months). The ALT perforator flaps had good appearance and color, with no further flap revision or defatting procedures. The static two-point discrimination was 8-15 mm (mean, 10.5 mm). All patients could walk and run normally without postoperative skin erosions or ulcerations. Conclusion The free thinned innervated ALT perforator flap is pliable and thin. It is suitable for repairing the donor site defects after wrap-around flap transfer for thumb reconstruction.

    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.

    Objective To explore the effectiveness of modified anterolateral thigh perforator flap pedicled by cross-bridge microvascular anastomosis in treatment of soft tissue defects in the middle and lower segments of the leg. Methods Between March 2011 and June 2015, 15 cases with skin and soft tissue defects in the middle and lower segments of the legs were treated. There were 9 males and 6 females, aged 22-48 years (mean, 32.6 years). Of whom, 8 patients caused by traffic accidents, 5 by machine twist, and 2 by crash injury of heavy object. The mean interval from injury to admission was 82.6 hours (range, 2 hours to 1 week). The area of defect ranged from 13 cm×9 cm to 23 cm×16 cm. After primary debridement and vaccum sealing drainage treatment, the defects were repaired with modified anterolateral thigh perforator flap pedicled by cross-bridge microvascular anastomosis. The size of flap ranged from 15 cm×10 cm to 25 cm×15 cm. The donor sites were sutured directly or repaired with the skin grafts. The pedicle division was done at 4 weeks after operation. Results After operation, venous crisis occurred in 1 case and distal skin necrosis in 2 cases which was healed by dressing change. The other tissue flaps survived successfully and wounds healed by first intention. All skin grafts at donor site survived after operation, and primary healing of wound was obtained. All patients were followed up 6-24 months (mean, 13 months). All flaps were characterized by soft texture, satisfactory appearance, and restoring the protective sensation. Moreover, the two-point discrimination ranged from 15 to 28 mm (mean, 19.5 mm) at 6 months after operation. The function of both lower extremities were normal without obvious contracture of scar at donor site. Conclusion Modified free anterolateral thigh perforator flap, with little damage in donor site, a reliable blood supply by making a cross-bridge microvascular anastomosis with pretibial or posterior tibial blood vessel on normal leg, is a reliable alternative method for repairing soft tissue defects with the main vessels of serious injury in the middle and lower segments of the leg.
