What is a VA Shunt and what does it do?

This is a device which drains the extra fluid in the brain into the right atrium of the heart. A shunt catheter is placed into a vein in the neck and threaded down where the vein joins a larger vein called the Superior Vena Cava. This large vein returns blood to the right atrium of the heart . The cerebral spinal fluid is added to the blood supply and is absorbed.
