WebShunt. Shunt system. The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt. It consists of a long, flexible tube with a valve that keeps fluid from the brain flowing in the right direction and at the proper rate. One end of the tubing is usually placed in one of the brain's ventricles. WebHow It Works. A shunt usually consists of two catheters and a one-way valve. The valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brain’s ventricles. As the pressure of cerebrospinal fluid inside the brain increases, the one-way valve opens and the excessive fluid drains to the downstream cavity.
