Global Cmtc-Ovm Organisation

Global Cmtc-Ovm Organisation For people with Vascular Malformations, their families and healthcare professionals. This the main page for English.

The worldwide CMTC-OVM is since 1997 the source for people who suffer from vascular malformations such CMTC. Our commitment is to support the welfare, foster well being of our patients and support the scientific research of vascular malformations. The patients in our organisation have the unique opportunity to get the best research of the causes, diagnosis and the best treatment of issues related.

Someone with a vascular malformation will look different in some way to other people which can lead to negative reactions from within their social environment and can give rise to psychological problems for the patient. Children affected by a vascular malformation often receive questions about this, because their condition is clearly visible. This can have a potentially negative influence on their social development and their performance at school. Other complications can vary from those of a cosmetic nature, visible veins for example, to those with serious and potentially fatal consequences. There are at least six known cases of children that have died as a result of complications thus far.

From May 19โ€“22, around 700 participants gathered in Philadelphia for the annual ISSVA congress , bringing together doctors, researchers and patient organisations from around the world.

For CMTC-OVM, ISSVA is always an important opportunity to learn about new developments, meet professionals in the field and represent the patient perspective.

One of the developments we are particularly pleased about is the growing role of patient organisations within ISSVA. The new Patient Support Committee will help strengthen patient representation and create a bridge between patients and medical professionals.

There was also increasing attention for the psychological and psychosocial impact of vascular anomalies. Although ISSVA is a scientific organisation, it is encouraging to see more recognition that the visible and invisible effects of a vascular anomaly both matter.

We also attended a special session organised by Relay, where the first results of their clinical trial were presented. The results look promising and may be an interesting development for patients with PROS.

And then, of course, there was our stand! Our banner, clogs, information materials, stroopwafels and Limburg chocolate once again helped us connect with many doctors and other participants. ๐Ÿ‡ณ๐Ÿ‡ฑ

The congress also included a beautiful tribute to Dr. John Butler Mulliken, one of the founders of the vascular anomalies field and of ISSVA.

We came home with new contacts, new information and lots to follow up on. Another valuable few days for CMTC-OVM. ๐Ÿ’™

For us, WCRSD was about more than sharing what we do. It was about listening, learning and talking openly about what life with a rare disease really means.

A highlight was seeing our President, speak about mental wellbeing in rare disease.

The numbers are sobering:
๐Ÿง  19% have experienced suicidal thoughts
๐Ÿ’ผ 70% have reduced or stopped working
๐Ÿค More than half experience social isolation

Behind every statistic is a person and a family. Thatโ€™s why mental wellbeing deserves to be part of rare disease care โ€” not an afterthought.

Weโ€™re leaving Versailles with new ideas, new friends and plenty of motivation for what comes next. ๐Ÿ’™

What a wonderful day at the Efteling! ๐Ÿ‡ณ๐Ÿ‡ฑโœจ

On 4 July, 88 participants from the Netherlands, Belgium and Germany came together for our annual Family Day. A day full of fun, laughter, conversations and making new memories.

The Efteling was the perfect place for our community, with something for every age. Families enjoyed the attractions, shared stories, met new members and reconnected with familiar faces.
The best moments often happened in between the activities; during lunch, while walking through the park, or even while waiting in line. These small moments of connection are what make our CMTC-OVM family so special. ๐Ÿ’™

What a wonderful weekend in the beautiful Biesbosch! ๐Ÿ‡ณ๐Ÿ‡ฑโœจ

On 23 & 24 May, families from different countries came together for our annual Family Weekend. There was adventure, laughter, teamwork and โ€” most importantly โ€” plenty of time to connect with each other.

From being out on the water and exploring nature to fun challenges and creating new memories, every family could enjoy the weekend in their own way.

It was wonderful to see new members become part of our CMTC-OVM family and to see existing friendships grow even stronger. ๐Ÿ’™
Thank you to all families who joined us and helped make this weekend so special!
