Ultrasound-Guided Injection of Polidocanol Microfoam in the Management of Venous Leg Ulcers

Background: Venous leg ulceration is a frequent and severe complication of lower limb venous insufficiency. Compression therapy is associated with a protracted course of healing and multiple recurrences. Minimally invasive surgery (subfascial endoscopic perforating surgery) is only possible in a subset of patients with leg ulcers. Low-cost and noninvasive therapeutic procedures are needed as alternative treatments. Objective: To evaluate the efficacy and safety of sclerosant in microfoam in treating venous leg ulceration. Design: A retrospective study of medical records, pretreatmentandposttreatmentcolorphotographs,andecho Doppler in patients with venous leg ulceration. All patientswereevaluatedat6monthsaftertherapy,70%were also evaluated at 2 years, 25% at 3 years, and 14% at 4 or more years after treatment. They were assessed for complete (100%) ulcer healing, time to wound closure, and recurrence.
