Abstract:
Objective:To explore the surgical method and clinical effect of harvesting 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery in reconstruction of 2 defects in same or adjacent digits.Methods:From November 2017 to August 2021, 12 patients with 2 defects in same or adjacent digits were treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital with 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery. Among the patients, 1 had the defect in dorsal and palmar of index finger, 1 in thumb and index finger, 6 in index and middle fingers, 3 in middle and ring fingers, and 1 in ring and little fingers. The size of digit defects was 1.5 cm×0.8 cm-6.0 cm×3.5 cm. The size of flaps was 2.0 cm× 1.2 cm-8.0 cm×4.0 cm. All the patients were included in postoperative monthly follow-up to assess the recovery of recipient and donor sites at outpatient service, by telephone or WeChat.Results:All 24 flaps in 12 patients survived without vascular compromise and achieved 100% of survival rate. The follow-up period ranged from 4 to 18 months, with an average of 10 months. Six patients were treated with additional flap thinning and plastic surgery at 4 months after the primary surgery due to slightly bloated flaps. Otherwise, all the flaps in the recipient site had neither pigmentation, obvious hyperplasia nor scar pain. All flaps gained the protective sensations, however the assessment of TPD was not conducted. The flaps were wear-resist and had no ulceration. The texture of the flaps was soft with good elasticity, and the flap did not turn to purple or swelling when in cold. The functional recovery of 23 digits in 12 patients was evaluated according to the total active mobility (TAM) of the digits. It achieved excellent in 3 digits, good in 15 digits, and fair in 5 digits, with an excellent and good rate of 78.26%. A linear scar appeared at the donor site without obvious hyperplasia or scar pain. There were normal sensations around the scar and at the digit-tips. The blood supply to the digit-tips was normal.Conclusion:Harvest of multiple free pedicled perforator flaps from a single donor site of superficial peroneal artery is an effective method in reconstruction of 2 defects in same or adjacent digits at the same time. It has advantages of being a simple surgery procedure by sacrificing only one donor site. It achieves a minimal damage to the donor site and a reliable blood supply of the flap.
