A lumboperitoneal (LP) shunt is a medical device used to treat conditions that cause an excessive accumulation of cerebrospinal fluid (CFS) in the brain and spinal cord. This device helps to divert the fluid from the lumbar area of the spine to the peritoneal cavity in the abdomen, where it can be absorbed. It is commonly used in pediatric patients to manage conditions such as hydrocephalus and pseudotumor cerebri.
