procedure

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.

medication

Arteriovenous malformation embolization

Catheter-based embolization of pulmonary or hepatic AVMs to prevent serious complications such as stroke, brain abscess, or high-output cardiac failure.

surgical

Curry 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.
