BackgroundInfectious purpura fulminans is a disabling disease often leading to amputations. Free flaps preserve limb length, covering exposed areas. We examined the efficacy of free flaps for lower limb salvage in infectious purpura fulminans survivors by evaluating surgical management, walking ability and quality of life.MethodsThis single-center, observational, descriptive, retrospective study was conducted in from 2016 to 2019. Adult purpura fulminans survivors who received a free flap for lower limb salvage were included. Patient characteristics and data on surgical management and rehabilitation were collected. Quality of life (SF-36 questionnaire), limb function and walking ability were later evaluated post-surgically.ResultsThe 6 patients included, mean age 38 years, had all required amputations. Nine free flaps were performed to cover important structures in 7 cases and for stump resurfacing in 2. All flaps were successful. Patients resumed walking at a mean of 204±108 days after the onset of purpura fulminans. Post-surgical evaluation was performed at a mean of 30±9.3 months. Five patients required secondary revision. All were independent for the activities of daily living. Mean physical component score was 37.6±9.4 and mental component score was 44.6±13.2 (minimum 0, maximum 100).ConclusionsUse of the free flap in patients with infectious purpura fulminans, after multidisciplinary reflection, is an appropriate procedure that preserves limb length. In spite of secondary complications, preservation of limb length enables patients to resume walking, with relatively good independence and quality of life.Copyright © 2021 Elsevier Masson SAS.
