A Study of Enalapril in Treatment of Venous Malformations

Summary

The goal of this clinical trial is to explore if enalapril can be used to treat painful venous malformations. The main question it aims to answer are: \- Can enalapril reduce pain and volume of the malformation and increase quality of life in patients with painful venous malformations? Participants will: Receive a dose of enalapril 5 mg once daily. If it doesn't have effect the dose of enalapril will be increased to 10 mg daily after 3 months. The treatment duration will be 12 months, with an additional follow-up of 12 months. The visit frequency will be after 1, 3, 6,9 and 12 months and then a follow up visit at 18 and 24 months. Approximately 15 participants will be screened to achieve minimum 10 enrolled participants.
