PURPOSE: To report clinical and radiographic outcomes of patients with venous malformations (VMs) treated with bleomycin foam.
MATERIALS AND METHODS: Twenty patients (age, 2-68 y) presented with symptoms of swelling (n = 19; 95%), pain (n = 14; 70%), and bleeding (n = 4; 20%). Lesions were located in the head and neck in 17 patients (85%), extremities in two (10%), and mediastinum in one (5%). Twenty-seven embolizations were performed, with a mean of 1.7 ± 1.0 treatments per patient (range, 1-4). An average of 0.45 ± 0.4 U/kg of bleomycin foam was used per procedure, with a range of 0.1-2.3 U/kg.
RESULTS: All procedures were technically successful with no intraprocedural complications. Mean follow-up was 66 days ± 80, with a range of 4-403 days. Postprocedure complications were minor in 6 of 27 procedures (22%) and major in 2 of 27 procedures (7%). All 20 patients (100%) reported improvement in their symptoms after a single treatment session. Postprocedural magnetic resonance (MR) imaging demonstrated volume reduction of treated lesions in 13 of 14 patients (93%), with a mean lesion volume reduction of 66% ± 21. Enhancement on MR imaging after treatment was decreased in 11 of 14 patients (79%), increased in two (14%), and stable in one (7%). T2 signal intensity on MR imaging after treatment was decreased in 12 of 14 patients (86%) and stable in two (14%).
CONCLUSIONS: The use of bleomycin foam for the percutaneous treatment of VMs is safe and effective. Foaming bleomycin may be used to address the dose limitations of the liquid.
