Advocacy Organizations
Collaborative Research Advocacy for Vascular Anomalies Network (CaRAVAN)
As the research-based umbrella organization for all vascular anomalies, we are on a mission to develop a unified network of patients and their families, advocates, researchers, and clinicians who influence research from initial concept and design to patient care delivery
Project FAVA
Project FAVA is a 501(c)(3) non-profit patient advocacy group that promotes awareness of fibro-adipose vascular anomalies, educates patients, their families, and the global community, and provides helpful resources to those with FAVA. Project FAVA also advances research to move the needle towards more effective and less invasive treatment options for FAVA patients.
