摘要： Venous malformations (VMs) are problematic common vascular malformations that are challenging even for experienced physicians. Several treatments are available including sclerotherapy, surgery, laser or combinations of these procedures. As none of these is specific, we still need therapies that would allow to cure these patients without complications. Hopefully, the unraveling of the causative defects of VMs will give us new tools for the management of this difficult condition.
