The placement of a ventricular catheter, or shunt tube, is a minimally invasive procedure in which a tube made of flexible plastic or silicone is placed in one of the brain’s ventricles. Cerebrospinal fluid (CSF) is the clear liquid surrounding the brain and the spinal column. An excess of CSF in the brain ventricles is brought on by infection or disease. A ventricular shunt is put into place to relieve pressure on the brain caused by hydrocephalus via drainage of excess fluid.
The ventricle can swell to a large size and place severe pressure on adjacent brain structures. Causes for hydrocephalus may include a brain tumor, infection of or bleeding into the cerebrospinal fluid, or brain malformations.
How The Instrument Works
The shunt drains fluid from the brain to the jugular vein in the neck, or a cavity in the abdomen. The brain and the drainage site must be accessed surgically. Catheter tubing ensures a one-directional flow of fluid to the drainage site. Valves in the tubing also self-regulate the amount of fluid which is drained.
A reservoir system attached to the tubing near the scalp can be checked to analyze CSF for bacteria, cancer cells, blood or protein levels. The reservoir may also be used as the site for the injection of antibiotics to treat infection.
A decrease in ventricular size is typical within three or four days after shunt placement. Ventricle shrinkage will occur even in chronic cases of hydrocephalus. Empirical signs of improvement become present within a few weeks. Circumstances surrounding the cause, type and severity of hydrocephalus can affect the outcome of surgery.
