What is hereditary hemorrhagic telangiectasia?

hereditary hemorrhagic telangiectasia (HHT) is a rare, genetic state. This affects the way in which blood vessels are formed and can create problems with how they work and communicate. In particular, some blood vessels in a person with HHT do not have the necessary connection of capillaries between arteries and veins. This lack of connections creates a high -pressure blood flow between veins and arteries, resulting in the fragility of the veins at the point of connection of the artery/vein that can cause bleeding or bleeding.

The absence of a capillary connection in hereditary hemorrhagic telangiectasia does not occur in all connections of the vein/artery. However, it can occur in different areas of the body and affect small or large arteries and veins. The size of the vessels determines whether delicate and susceptible to bleeding is referred to as telangiectasia or arteriovenous malformations. The latter may be more dangerous and placed in areas such as lungs or brain, which represents important property if it begins to bleed. Many telangiectas are presentNear the skin or near mucous membranes and one characteristic feature of this condition are frequent nosebleeds, or visible evidence of telangiectas to the skin. One species, called Juvenile HHT, has another function. People can be prone to the development of polyps in their intestinal tract except for these capillary venous connections.

All types of this condition are inherited. The inheritance formula is autosomal, which means that people only need to inherit a single gene from a single parent to express the disease. This also means that people with HHT have a 50% chance to pass the condition to any offspring.

Some of the most common HHT symptoms include Nosebleeds, to which may occur and the presence of purple or red spots (telangiectasis) on the face or skin in half of their lives. People can also show bleeding in other places where the matter is more serious. A stomach may appear,Helor, brain or pulmonary bleeding and find that one has hereditary hemorrhagic telangiectasia is important, so these potential risks can be monitored. If the bleeding occurs regularly but is not serious, some people become anemic and blood tests could be performed frequently to seek this sign.

It is important to realize that the expression of symptoms is very different and many symptoms can be controlled or medically controlled. For example, the use of moisture at home can help with frequent noses. Unsilicient or annoying telangiectasis can be surgically removed. A number of surgical interventions are useful in repairing arteriovenous malformations, so severe bleeding does not occur internally. People with HHT need careful monitoring of a specialist, but many of them can live very normal lives very few interventions.

One thing all people with hereditary hemorrhagic telangiectasia tend to require prophylaxis bacterial endocarditis (BE). This is the treatment of antibiotics fromtaken in front of dental procedures. The weakness in the columns of membranes in the mouth creates a more likely that bacteria enter the bloodstream, which can cause infection in the heart. Anyone with HHT should inform the dentist to make sure that this preventive measure is observed, even for simple things like brushing teeth.
