Hereditary hemorrhagic telangiectasia

Hereditary Hemorrhagic Telangiectasia

HHT may affect many different organs, so presenting symptoms of HHT depend on the location of the vascular lesions.

The diagnosis of HHT is based on 4 specific criteria referred to as the Curacao Criteria and include: spontaneous recurrent nose bleeds; multiple telangiectasias in typical locations; proven arteriovenous malformations in the lungs, liver, brain, or spine; and first-degree family member with HHT.

Symptoms

Signs and symptoms may include nosebleeds, acute and chronic digestive tract bleeding, coughing up blood, and anemia. If the bleeding vascular lesions are located in the brain, the person may present with headaches and signs and symptoms of a stroke.
