A ventriculoatrial (VA) shunt is a medical device used to treat hydrocephalus, a condition characterized by excessive accumulation of cerebrospinal fluid (CSF) within the brain's ventricles. In hydrocephalus, the excess CSF causes increased intracranial pressure, which can lead to brain damage. The VA shunt helps to divert the CSF from the ventricles to the right atrium of the heart, where it can be absorbed into the bloodstream.
