New HHT International Guidelines Released
Announcing the Second International HHT Guidelines for the Diagnosis and Management of HHT, published in the Annals of Internal Medicine. The Guidelines were developed by an international panel of HHT experts and patients, providing new evidence-based consensus recommendations in six priority topic areas: Epistaxis, Gastrointestinal Bleeding, Anemia & Iron Deficiency, Liver VMs, Pediatric Care, Pregnancy & Delivery. The 2020 Guidelines add to the First International HHT Guidelines published in 2009, most notably in areas that were not re-assessed in 2020: HHT Diagnosis, Brain VMs and Pulmonary AVMs. The HHT Guidelines recommendations should facilitate the implementation of key components of HHT (Hereditary Hemorrhagic Telangiectasia) care into clinical practice.

Liver VMs occur in approximately 75% of HHT patients, and are more common in women. These seven recommendations cover screening, diagnosis and management.
Potentially serious and life-threatening complications from HHT--pulmonary AVMs and brain VMs -- can occur at any age. As such, these guidelines focus on their screening and management in children.
