Percutaneous Sclerotherapy of Symptomatic Liver Hemangioma With Bleomycin

Percutaneous sclerotherapy is currently a widely used treatment for subcutaneous low-flow vascular malformations. Considered as a low-flow vascular malformation, symptomatic liver hemangiomas could also theoretically be safely and effectively treated by percutaneous sclerotherapy with a mixture of Bleomycin and Lipiodol. The safety and efficacy of percutaneous sclerotherapy was firstly introduced by the investigator's investigators in 5 patients in a pilot study. The aim of this study is to design and conduct a study to evaluate the safety and efficacy of percutaneous sclerotherapy in a larger sample size with a long term follow-up.
