What can hereditary hemorrhagic telangiectasia cause?
Hereditary hemorrhagic telangiectasia (tuh-lan-jee-uk-TAY-zhuh) is an inherited disorder that causes abnormal connections, called arteriovenous malformations (AVMs), to develop between arteries and veins. The most common locations affected are the nose, lungs, brain and liver.
How does hereditary hemorrhagic telangiectasia affect the body?
A person with HHT may form blood vessels without the capillaries (tiny blood vessels that pass blood from arteries to veins) that are usually present between arteries and veins. The space between an artery and a vein is often fragile and can burst and bleed much more easily than other blood vessels.
Does HHT weaken your immune system?

What is telangiectasia a symptom of?
Telangiectasia that appear as dilated loops of capillaries with the avascular areas (areas lacking blood vessels) on the fingernail folds are highly characteristic of both scleroderma and dermatomyositis. These findings can help physicians make an early diagnosis of these conditions.
What is HHT stroke?
•A condition that causes abnormally formed blood vessels, which increases risk for clots. •Symptoms include nosebleeds or ischemic stroke. •Treatments include embolization, surgery, and stereotactic radiosurgery.
Is hereditary hemorrhagic telangiectasia fatal?
HHT can be fatal if the AVM is in the patient’s brain, lungs or GI tract (stomach and intestines). AVMs in the GI tract do not cause pain or discomfort. Symptoms of GI bleeding are black or bloody stools and/or anemia. The anemia (low blood count) can then cause fatigue, shortness of breath, chest pain or dizziness.

What is Osler Weber syndrome?
Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is a rare genetic disorder that affects the blood vessels in the body.
What is capillary telangiectasia in the brain?
Capillary telangiectasias (CTSs) are small areas of abnormally dilated capillaries within otherwise normal brain tissue. Although CTSs most commonly occur in the pons, they have been described throughout the brain.
What is hereditary hemorrhagic telangiectasia?
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by epistaxis, telangiectases, and multi-organ vascular dysplasia. Head and neck localizations of HHT are recurrent, frequent associated with serious complications.
What are the signs and symptoms of hemorrhagic telangiectasia?

What are telangiectasias (AVMs)?
People with HHT can develop abnormal blood vessels called arteriovenous malformations (AVMs) in several areas of the body. AVMs on the skin are called telangiectasias.
