HHT Clinic: What Is Hereditary Hemorrhagic Telangiectasia?

HHT, also known as Osler-Weber-Rendu syndrome, is a genetic condition in which there is an abnormality in the formation of the small blood vessels. HHT affects approximately one in 5,000 people. Males and females from all racial and ethnic groups are affected equally by the condition. Most often, individuals present with nosebleeds or visible red spots (telangiectasias) on the skin. Patients can also develop arteriovenous malformations (AVMs) in various body organs. AVMs may rupture with bleeding in vital organs such as lungs, intestines, brain, or spine. Although telangiectasias or AVMs cannot be prevented, they can be treated to avoid complications of bleeding and anemia. Younger family members can be screened to prevent life-threatening bleeding.
