Official Title: An Investigational Pilot Study to Evaluate Sildenafil for the Treatment of Lymphatic Malformations
Brief Summary: There is an unsatisfied medical need for a first-line treatment of lymphatic malformations with a good benefit/risk profile. Based on a patient experience in the institution, the investigators plan to verify whether or not the medication sildenafil has a beneficial effect on lymphatic malformations. The investigators plan to do this by treating patients with lymphatic malformations with the medication sildenafil for a 20 week period. This is an investigator initiated study funded by an Innovations in Patient Care grant and a SPARK grant.
