A type of bleeding caused due to the malfunctioning of blood vessels is known as Hereditary Hemorrhagic Telangiectasia. This is a disorder which the patient inherits from his or her parents. A typical case is of nosebleed that prolongs and which occurs frequently. There are other symptoms an affected person may experience, depending on the type of the particular disorder they have inherited.
HOW IS HEREDITARY HEMORRHAGIC TELANGIECTASIA DIAGNOSED?
HHT can be diagnosed by performing genetic testing. Genetic testing can detect a gene mutation in about ¾ of families with signs of HHT, which if found can establish the diagnosis of HHT in individuals and families who are unsure about whether they have HHT. A clinical diagnosis of HHT can be made if one has at least three of these four criteria:
• Recurrent nosebleeds that seem to start for no reason
• Visible telangiectases on the lips, mouth, fingers, nose and the inside of the mouth
• Internal telangiectases in the lungs, brain, spine, digestive tract or liver
• Family history of a parent, sibling or child with HHT
HOW IS HEREDITARY HEMORRHAGIC TELANGIECTASIA TREATED?
No cure exists for HHT, but treatment can help avoid serious complications caused by abnormal blood vessels. Treatment may include controlling bleeding and anaemia and preventing complications from abnormal artery-vein connections in the lungs and brain.
