ABSTRACT

Objective: To investigate the clinical application of the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap in repair of foot and ankle defects. Methods: Between October 2014 and October 2018, 18 cases with foot and ankle defects were treated. There were 12 males and 6 females with an average age of 32.8 years (range, 8-56 years). There were 11 cases of traffic accident injuries, 3 cases of falling from height injuries, and 4 cases of heavy objects injuries. The wound was at the dorsum of the foot in 9 cases, the heel in 4 cases, the lateral malleolus in 5 cases. The time from injury to flap repair was 7-34 days (mean, 19 days). The size of wound ranged from 6.0 cm×2.5 cm to 11.0 cm×6.0 cm. The foot and ankle defects were repaired with the peroneal artery terminal perforator propeller flap in size of 6 cm×3 cm-18 cm×7 cm, which donor site was repaired with the anterior tibial artery perforator propeller flap in size of 8 cm×3 cm-16 cm×6 cm. Results: One patient had a hemorrhagic swelling in the peroneal artery terminal perforator propeller flap, and survived after symptomatic treatment. All recipient and donor sites healed by first intention. Eighteen patients were followed up 6-15 months (mean, 12.5 months). At last follow-up, the shape, color, texture, and thickness of the flaps in the donor sites were similar with those in the recipient sites. There were only linear scars on the donor sites. The two-point discrimination of the peroneal artery terminal perforator propeller flap ranged from 10 to 12 mm (mean, 11 mm). According to American Orthopaedic Foot and Ankle Society (AOFAS) score criteria, the results were excellent in 15 cases and good in 3 cases, with an excellent and good rate of 100%. Conclusion: The foot and ankle defects can be repaired with the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap. The procedure is not sacrificing the main vessel and can avoid the skin grafting and obtain the good ankle function.

ABSTRACT

Objective: To investigate the feasibility and effectiveness of the latissimus dorsi myocutaneous flap in repair of large complex tissue defects of limb and the relaying posterior intercostal artery perforator flap in repair of donor defect after latissimus dorsi myocutaneous flap transfer. Methods: Between January 2016 and May 2017, 9 patients with large complex tissue defects were treated. There were 8 males and 1 female with a median age of 33 years (range, 21-56 years). The injury caused by traffic accident in 8 cases, and the time from post-traumatic admission to flap repair was 1-3 weeks (mean, 13 days). The defect in 1 case was caused by the resection of medial vastus muscle fibrosarcoma. There were 5 cases of upper arm defects and 4 cases of thigh defects. The size of wounds ranged from 20 cm×12 cm to 36 cm×27 cm. There were biceps brachii defect in 2 cases, triceps brachii defect in 3 cases, biceps femoris defect in 2 cases, quadriceps femoris defect in 2 cases, humerus fracture in 2 cases, brachial artery injury in 2 cases, and arteria femoralis split defect combined with nervus peroneus communis and tibia nerve split defect in 1 case. The latissimus dorsi myocutaneous flaps were used to repair the wounds and reconstruct the muscle function. The size of the skin flaps ranged from 22 cm×13 cm to 39 cm×28 cm; the size of the muscle flaps ranged from 12 cm×3 cm to 18 cm×5 cm. The wounds were repaired with pedicle flaps and free flaps in upper limbs and lower limbs, respectively. The donor sites were repaired with posterior intercostal artery perforator flaps. The size of flaps ranged from 10 cm×5 cm to 17 cm×8 cm. The second donor sites were sutured directly. Results: All the flaps survived smoothly and the wounds and donor sites healed by first intention. All patients were followed up 10-19 months (mean, 13 months). At last follow-up, the flaps had good appearances and textures. The muscle strength recovered to grade 4 in 5 cases and to grade 3 in 4 cases. After latissimus dorsi myocutaneous flap transfer, the range of motion of shoulder joint was 40-90°, with an average of 70°. The two-point discrimination of latissimus dorsi myocutaneous flap was 9-15 mm (mean, 12.5 mm), and that of posterior intercostal artery perforator flap was 8-10 mm (mean, 9.2 mm). There were only residual linear scars at the second donor sites. Conclusion: The latissimus dorsi myocutaneous flap combined with posterior intercostal artery perforator flap for the large complex tissue defects and donor site can not only improve the appearance of donor and recipient sites, but also reconstruct muscle function, and reduce the incidence of donor complications.
