Hereditary Hemorrhagic Telangiectasia (HHT)

Cure HHT Center of Excellence

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, is a rare genetic condition that causes bleeding due to blood vessels that did not develop correctly. HHT causes arteriovenous malformations (AVMs) — tangled connections between arteries and veins. AVMs can affect different organs, including the gastrointestinal system, skin, lungs, liver and brain. Complications from arteriovenous malformations range in severity from discoloration of the skin to bleeding and disruption of normal organ function.
