A shunt, in medical terms, is a device or procedure that redirects the flow of bodily fluids. It is often used to treat conditions where normal fluid drainage is obstructed, such as in cases of hydrocephalus, where excess cerebrospinal fluid accumulates in the brain. By creating an alternative pathway, a shunt helps to relieve pressure and prevent damage to surrounding tissues. Shunts can be made from various materials and come in different designs, depending on their specific purpose. For example, a ventriculoperitoneal shunt is commonly used to drain fluid from the brain to the abdominal cavity. This diversion helps maintain proper fluid balance and supports overall health.
