游离上臂外侧皮瓣在手部皮肤软组织缺损中的应用.

Objective To explore the clinical efficacy of lateral upper arm free flap transplantation in the repair of small and medium-sized skin and soft tissue defects of hand. Methods From January 2015 to January 2020, 15 patients with skin and soft tissue defects of hand were repaired by lateral upper arm free flap transplantation. The area of defects ranged from 1.5 cm × 5.0 cm to 5.0 cm × 7.0 cm. All patients were followed up for 6 to 12 months. The survival rate, color, temperature, capillary filling reaction and sensory recovery of flap were observed. The complications of recipient site were counted and the sensory function of hand was evaluated. Results One patient developed venous crisis after operation, which healed after timely exploration and reanastomosis. Thirteen flaps survived, 2 flaps had partial necrosis and healed after dressing change. Three cases of flaps were slightly bloated and two-stage flap repair was performed at 6 months after operation. The remaining patients had good texture and appearance of flap. The recovery of hand function was satisfactory, 14 cases were excellent and 1 case was good. The sensory recovery of hand was good. No serious complications occurred in the recipient area. Conclusion The lateral upper arm free flap is an ideal flap in the repair of small and medium-sized skin and soft tissue defects of hand.
