HHT is an inherited disorder that affects blood vessels. It is characterized by abnormal connections between arteries and veins known as arteriovenous malformations (AVM’s) and telangiectases. AVM’s occur in the brain, spine, liver and lungs. Telangiectases are found in the mucocutaneous surface areas of the gastrointestinal tract, skin and nose.
Manifestations of HHT include:
- Recurrent epistaxis (nosebleeds)
- AVM’s in solid organs
