About the Surgery
Shunts typically consist of two catheters and a valve that redirect excess fluid from the brain to another part of the body. Implanting shunts usually takes less than an hour, and may help relieve symptoms of normal pressure hydrocephalus.
A shunt usually consists of two catheters and a one-way valve. Shunts allow excess cerebrospinal fluid to drain to another area of the body.
All treatment and outcome results are specific to the individual patient, and will form part of your consultation with your healthcare professional.
Please consult your healthcare professional for a full list of benefits, indications, precautions, clinical results, and other important medical information that pertains to shunts.
Shunts have been used to treat hydrocephalus for more than 50 years. The devices allow excess cerebrospinal fluid to drain to another area of the body.
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 or spine increases, the one-way valve opens and the excessive fluid drains to the downstream cavity.
Typically, the fluid gets “shunted” (moved) using the following shunt types:
There are various types of shunt valves. The two most common are:
Both of these valve types can include a siphon control device. The purpose of this device is to minimise excessive drainage due to gravity when a person is in the upright position.
