?:definition
  • Ventricular intracranial catheters designed to be used as proximal catheters in the treatment of obstructions of the cerebrospinal fluid pathways accompanied by an accumulation of cerebrospinal fluid within the skull (hydrocephalus); they are usually made of silicone elastomers (silastic). These catheters are usually placed in the anterior horn of the lateral ventricle through a small burr hole, typically in the right parietooccipital region. Hydrocephalic ventricular catheters are typically connected through a valve and/or a reservoir to another catheter that drains the cerebrospinal fluid in the peritoneum or the left atrium of the heart; these devices as a whole are known as ventriculoperitoneal and ventriculoatrial shunts, respectively. Hydrocephalic ventricular catheters are used in treating children and adults with hydrocephalus, which may be idiopathic or the result of congenital malformation, neoplasms of the brain, brain cysts, or traumatic injury.
