This condition has significant mortality risk and requires specific protocols for medical procedures, pregnancy, and emergency management.

Documentation Requirements

✓Documentation of major criteria (arterial rupture, bowel perforation, uterine rupture)
✓Characteristic facial features
✓Thin, translucent skin with visible veins
✓Family history of vascular complications
✓Cardiac echocardiogram and vascular imaging results
