Life-threatening Anaemia in Patient with Hereditary Haemorrhagic Telangiectasia (Rendu-Osler-Weber Syndrome).

Hereditary haemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is a rare autosomal dominant vascular disorder. Patients with HHT may present with a wide spectrum of clinical manifestations from epistaxis to clinically significant arteriovenous malformations (AVM) in the lungs, liver, brain and spine. The diagnosis of HHT is based on clinical criteria. There is a long diagnostic delay of nearly 3 decades since disease onset. The treatment is based on various types of haemostasis. There is ongoing research with potential therapies which may prevent and decrease the severity of epistaxis. Thalidomide may be an effective treatment to decrease the bleeding symptoms of patients with HHT.
