Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder that causes some blood vessels to develop improperly. Yale radiologists are developing guidelines for the evaluation of blood vessel malformations in the lungs (pulmonary arteriovenous malformations) in children with HHT. This innovative approach will replace CT scans, avoiding the successive and often unnecessary radiation exposure for children who have no symptoms.
We are also developing guidelines for the diagnosis and treatment of malformed blood vessels in the brain (cerebral arteriovenous malformations), and aim to have these guidelines become part of the standard of care. Our physicians are also examining potential liver transplant guidelines for patients with HHT in heart failure. We are continuously analyzing existing data and conducting evidence-based research to develop new treatment methods that can impact the lives of patients in our care.
