Hereditary Haemorrhagic Telangiectasia (HHT) is also known as Osler-Rendu-Weber syndrome. It is a rare inherited (autosomal dominant) disorder that affects blood vessels throughout the body and is characterised by a tendency for bleeding (haemorrhage), in particular recurrent epistaxis (nose bleeds) and skin telangiectasia.

There are several genetic mutations that have been associated with HHT including: ENG, ACVRL1 / ALK1 and SMAD4 among others. An inherited alteration in just one of these genes causes an abnormality in the formation of blood vessels, which may easily rupture and bleed. The abnormal dilated blood vessels are known as telangiectases, or arteriovenous malformations (AVM), if larger blood vessels are involved.

Most people with HHT can be treated symptomatically. AVMs may need active management. HHT should be treated if it is causing significant problems, such as severe and / or frequent nosebleeds. Ideally, a multidisciplinary clinical team should assist in the care of those with HHT.

Hereditary Haemorrhagic Telangiectasia – Family Day
