Atresia

Atresia is a congenital absence or abnormal narrowing of any opening or canal in the human body.

  1. Examples of atresia:
  1. Biliary atresia affects the bile ducts and causes obstructive jaundice in infants. If the child is not operated on in time, the disease can be fatal.

  2. With atresia of the tricuspid valve (tricuspid atresia), intracardiac blood flow is disrupted, because the flow of blood from the right atrium to the right ventricle is disrupted.

  1. Atresia can also refer to degenerative changes that occur in most ovarian follicles. Typically, only one Graafian vesicle (follicle) ovulates during each menstrual cycle.

  2. Atretic - related to atresia.



A person may be surprised to see that a colleague had an abnormality as a child, but most birth defects do not occur by chance. They occur due to genetic disorders or environmental factors. One such defect is atresia, a congenital abnormality or absence of something in the body.

Today we will look at two types of atresia: vitelline duct atresia and tricuspid atresia. Both cause serious problems in the body and can lead to death if not treated promptly.

Vitelline tubular atresia is a lack of communication between the intrahepatic bile ducts and bile, a waste liquid secreted by the liver. This means that children suffering from biliary atresia cannot properly remove toxins from their blood, resulting in stunted growth, abnormal development, and even death. But not all atresis lead to such severe consequences. Atresis of the tricuspid valve is not as serious as atresis of the vitelline anals. The tricuspid valve is the valves in the heart that regulate the flow of blood from left to right and right to left. When any reason prevents the valve from functioning properly, it does not work correctly, allowing blood to flow where it does not belong. The person experiences blood flow problems such as heartbeat problems, heart failure and death.

It is important to note that both types of atresis are pathologies that appear from birth, so doctors should pay special attention to them.
