Abstract
We report two patients with venous malformation (VM) who were successfully treated by embolosclerotherapy. Case 1 is a woman in her 20s, who presented with right upper arm pain due to a brachial intramuscular VM. She underwent two sessions of percutaneous sclerotherapy, however, the pain relief was insufficient. Since her VM appeared to be an ‘intermediate-flow’ lesion based on the findings of dynamic MRI, we tried embolosclerotherapy consisting of feeding-artery-embolizations using gelatin sponge particles and following percutaneous sclerotherapy using ethanol. The treatment effect was significant, and prolonged pain control was obtained without any additional treatment. Case 2 is a woman in her 20s who had the tongue and buccal mucosal VMs. She suffered from bleeding due to biting of the oral cavity VMs. We treated these lesions with 2 sessions of embolosclerotherapy. In this case, to avoid mucosal necrosis we did not use ethanol, and 3% polidocanol was used as a sclerosant. Additional percutaneous sclerotherapy was repeated 3 times in every 4 months at the outpatient clinic. After these treatments, both the tongue and buccal mucosal lesions shrank enough to be resected.
