Hydrocephalus in Dogs and Cats

Abstract

Hydrocephalus is a common congenital or acquired neurologic disorder in dogs and cats. Although a differential diagnosis for the disorder exists, the underlying cause of congenital hydrocephalus is often unknown. Medical treatment decreases cerebrospinal fluid volume and production but offers only temporary palliation of clinical signs. Advances in shunt technology have allowed ventriculoperitoneal shunt placement to treat congenital hydrocephalus and as an adjunct in managing secondary hydrocephalus.This article discusses the pathophysiology and medical and surgical treatment of hydrocephalus.
