Clinical application of free inguinal flaps with retrograde blood supply anastomotic to repair soft tissue defects of extremities

To observe the clinical efficacy of free inguinal flaps with retrograde blood supply anastomosis to repair skin and soft tissue defects in the limbs. A total of 25 patients with soft tissue defects of the limbs treated from January 2019 to December 2021 were selected and repaired with free inguinal flaps anastomotic with retrograde blood supply. All 25 skin flaps survived; 1 patient had skin flap infection and the wound healed gradually after symptomatic treatment, and 1 patient had venous embolism and the skin flap survived after re-anastomosis. The patients were followed up for 6 to 18 months after the operation. After healing, the patient recovered satisfactorily, and the flap had a good appearance, texture, and flexibility; a reoperation was not required. The patient was satisfied with the effect of the treatment. Retrograde vascular anastomosis with the anterolateral femoral perforator flap is safe and reliable for repairing the soft tissue defects of the limbs. It is convenient for micromanipulation and can achieve satisfactory clinical results, and thus is an ideal repair method.
