Abstract:
Objective:To investigate the clinical effect of Flow-through perforator flap of posterior interosseous artery in repair of dorsal digital soft tissue defect with disorder of blood supply in digital tip.Methods:From January 2018 to June 2020, 12 patients who had digital dorsum soft tissue defect with digital tip blood supply disorder were treated with Flow-through perforator flap of posterior interosseous artery. The size of flaps was 2.0 cm× 2.0 cm-5.5 cm×3.0 cm. The posterior interosseous artery in the flap was bridged with the proper palmar artery of digit, 1 subcutaneous vein in the flap was anastomosed with the dorsal subcutaneous vein, and 1 subcutaneous vein in the posterior interosseous artery with the palmar subcutaneous vein. The donor sites were sutured directly. The wound healing, blood supply of digit and flap survival were observed after operation. The quality of flap survival and digital joint function were observed in the follow-up reviews at outpatient clinic.Results:All the 12 Flow-through perforator flaps of posterior interosseous artery survived, the blood supply of digit was good, and the wounds healed in the first stage. The follow-up period was 6-24 months. The appearance and texture of the flaps were good without obvious bloating. Only linear scar was left in the forearm donor site. According to the Trial Standard of Upper Limb Function Evaluation of Chinese Society of Hand Surgery, the results were excellent in 11 cases and good in 1 case.Conclusion:The perforator flap of posterior interosseous artery has constant anatomy, and the diameter of blood vessel matches the blood vessels of digits. It is suitable for Flow-through technique. It has less subcutaneous tissue, no secondary thinning, and the donor site can be closed directly. It is a good method to repair the dorsal soft tissue defect with disorder of digital end blood circulation.
