Q89.01: Asplenia (congenital)

The spleen has not developed.

The spleen is on the top left side of the abdomen. Old blood cells are broken down in the spleen. Furthermore, defense cells are stored. If the defense cells are needed, they are then released from the spleen into the blood. The spleen forms part of the immune system.

While developing in the womb, many different types of tissue develop in the body. The organs and body parts develop out of the various types of tissue.

If the spleen fails to develop, it weakens the immune system. This can result in recurring, severe infections. If the spleen is not breaking down old blood cells, there may be too many platelets in the blood, for example. Platelets are important for blood clotting. When there are too many platelets in the blood, blood vessels can get blocked.
