Multiple free homologous superficial peroneal artery perforator flaps of crus for repair of multiple hand wounds / 中华烧伤杂志

ABSTRACT

Objective@#To explore the effects of multiple free homologous superficial peroneal artery perforator flaps of crus for repair of multiple hand wounds.@*Methods@#From November 2017 to December 2018, eight cases with eighteen hand wounds were hospitalized in our unit. Among them, wounds were distributed in the forefinger and middle finger in four cases, wounds were distributed in the middle finger and ring finger in two cases, wounds were distributed in the forefinger, middle finger, and ring finger in one case, and wounds were distributed in the middle finger, ring finger, and little finger in one case. The area of skin defect ranged from 1.5 cm×0.8 cm to 4.0 cm×3.0 cm. There were 4 males and 4 females, aged 34-62 years. Wounds of six cases were repaired by two free superficial peroneal artery perforator flaps from homolateral crus, and those of two cases were repaired by three free superficial peroneal artery perforator flaps from homolateral crus. Superficial peroneal artery and its accompanying vein of flap were anastomosed by end to end with digital artery and palmar or dorsal subcutaneous vein of recipient site during the operation. The area of flap ranged from 2.5 cm×1.2 cm to 5.0 cm×4.0 cm. No nerve was harvested during the operation, and donor site was sutured directly. The survival of the flaps and the healing of donor sites were recorded. During follow-up, the recovery of donor and recipient sites was observed.@*Results@#All flaps survived well, donor site healed well. No vascular crisis occurred. Follow-up for 4 to 12 months showed that the appearance of flap was satisfactory with good color, texture, elasticity, and function. Protective sensation of recipient site was recovered. Five months after operation, flap of finger pulp in one case was swollen slightly with two-points discrimination of 10 mm, which received the thinning surgery. Obvious scar formation was not observed in donor site of crus. The appearance of the donor site was good without functional damage.@*Conclusions@#The application of multiple free homologous superficial peroneal artery perforator flaps of crus to repair the multiple hand wounds has advantages of easy acquisition, easy operation, little effect on donor sites, and satisfactory clinical effects.
