Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Antifibrinolytic therapy
Oral tranexamic acid or aminocaproic acid to stabilize clots at bleeding sites, particularly effective for recurrent epistaxis and gastrointestinal bleeding in HHT.
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Laser photocoagulation therapy
Pulsed dye or Nd:YAG laser treatment to ablate visible telangiectasias on skin and mucous membranes, reducing spontaneous bleeding episodes and improving quality of life.
Additional treatment options
Iron supplementation and anemia management
Oral or intravenous iron replacement to counteract chronic blood loss from recurrent bleeding, maintaining hemoglobin levels and preventing iron deficiency anemia.
medicationArteriovenous malformation embolization
Catheter-based embolization of pulmonary or hepatic AVMs to prevent serious complications such as stroke, brain abscess, or high-output cardiac failure.
surgicalCurry criteria screening and AVM surveillance
Regular screening with contrast echocardiography, MRI, or CT to detect pulmonary and cerebral AVMs per HHT diagnostic criteria, enabling early intervention.
monitoringWhen to seek medical help
