Summary

This study follows 340 people with vascular Ehlers-Danlos syndrome (vEDS), a rare genetic condition that weakens blood vessels and organs. Researchers will track complications like artery tears, digestive issues, and pregnancy risks to better understand how the disease progresses. The goal is to improve care and quality of life for patients.
