How does a medical shunt work?

A medical shunt is a device that creates a passageway to redirect bodily fluids, such as blood or cerebrospinal fluid, from one area to another. It typically consists of a tube that connects two spaces, allowing fluid to bypass an obstruction or drainage issue. Shunts are commonly used in conditions like hydrocephalus, where excess cerebrospinal fluid is drained from the brain to the abdominal cavity, helping to relieve pressure and prevent complications. The effectiveness of a shunt relies on proper placement and maintenance to ensure that fluid flows correctly without blockage.
