Anastomosis Kavo-Kavalnaya

Cavo-caval anastomosis (a. cavo-cavalis) is a connection between the inferior vena cava and the superior vena cava, which can be performed surgically.

Anatomically, the inferior vena cava (vena cava) collects venous blood from the lower part of the body and drains into the right atrium. The superior vena cava also drains into the right atrium, but collects blood from the upper part of the body.

Creating an anastomosis between these two large veins may be necessary for some congenital or acquired diseases of the heart and blood vessels. For example, with some malformations there may be no connection between the superior vena cava and the right atrium. In this case, blood from the upper half of the body cannot enter the atrium and then into the right ventricle. A surgically created anastomosis between the superior vena cava and the inferior vena cava allows blood from the upper half of the body to still flow into the right atrium through the inferior vena cava.

Thus, cavo-caval anastomosis is an important surgical procedure for restoring normal venous blood flow in some congenital and acquired diseases of the cardiovascular system.
