Hereditary Hemorrhagic Telangiectasia (HHT)
Treatment of HHT
Stopping bleeding Iron supplements Sometimes blood transfusions Treatment of hereditary hemorrhagic telangiectasia is aimed at stopping or preventing bleeding. Treatment may involve applying pressure, using a topical medication that narrows blood vessels (astringent), or using a laser beam to destroy the leaking blood vessel in the nose or digestive tract. Severe bleeding may require more invasive techniques, including surgery. AVMs in the lungs, and sometimes in the liver, can be treated using a thin flexible tube (catheter) to insert a small device that blocks the affected blood vessel. In this procedure, doctors insert a catheter through one of the person's arteries and into the artery leading to the AVM. The doctor then passes a small coil or a plug through the catheter to stop the blood flow through the AVM. Bleeding almost always recurs, resulting in Iron Deficiency Anemia . People with hereditary hemorrhagic telangiectasia often need oral or intravenous iron supplements. People may also need repeated Other medications such asbevacizumab,pazopanib,pomalidomide, orthalidomidecan reduce the number and density of abnormal blood vessels. Of these, onlybevacizumabhas been shown to reduce the incidence of bleeding in the nose and digestive tract.
