Shunt surgery is a medical procedure used to treat conditions like hydrocephalus, where excess fluid accumulates in the brain. During the surgery, a small tube, called a shunt, is inserted to drain the excess fluid and redirect it to another part of the body, usually the abdomen. This helps relieve pressure on the brain and prevents further complications. The procedure is typically performed under general anesthesia and can be done using minimally invasive techniques. After the surgery, patients may need regular follow-ups to ensure the shunt is functioning properly and to monitor for any potential complications.
