The SVC is located in the anterior right superior mediastinum. It is the typical site of central venous access via a central venous catheter or a peripherally inserted central catheter. Mentions of “the cava” without further specification usually refer to the SVC.
What is bilateral superior vena cava?
The most common of the SVC anomalies is bilateral SVC, which means that both right and left superior caval veins are present. Both bilateral SVC and isolated left SVC can occur in the otherwise normal heart or be associated with congenital heart disease [1. U.
What is the function of the superior vena cava quizlet?

Thrombosis is a blood clot in a blood vessel, which leads to restricted blood flow and circulation throughout the body.
How does the superior vena cava protect the heart?
It protects and strengthens the vein and serves to attach the vein to surrounding structures. Most veins contain valves that help keep the blood moving in the direction of the heart, preventing the blood from backflowing away from the heart. The superior vena cava, however, is one of a few valveless veins in the body. 6
What kind of blood vessels are in the circulatory system?
Arteries and veins are the two primary types of blood vessels in the circulatory system of the body.
