CMTC-OVM
For People with CMTC and Other Vascular Malformations (OVM), their families and healthcare professionals.

CMTC-OVM is a global non-profit community that aims to improve the quality of life of people suffering from rare vascular malformations (blood vessel abnormalities) such as CMTC and Klippel-Trenanay, their families and to stimulate scientific research into these malformations.
Our worldwide non-profit organization, active since 1997, consists entirely of motivated volunteers. We can always use support in many areas. Think of this as a sponsor (such as products, services and money) but also of volunteers, members and donors.
