Vp Shunt Ventricular Catheter
A small hole is drilled in the skull.
Vp shunt ventricular catheter. Ventriculoperitoneal vp shunt is the most common neurosurgical procedure to treat obstructive and communicating hydrocephalus but failures are frequent. It can also be done with an endoscope that allows the surgeon to see inside the ventricle. Axial t2 mri without contrast of the brain above obtained 2 months ago shows normal ventricular size with a vp shunt in place.
Ventriculoperitoneal vp shunt placement is a procedure to help remove excess fluid in the brain. The external portion of the catheter is connected to a valve that regulates the flow of csf based on a preset pressure. One end of the catheter is passed into a ventricle of the brain.
The shunt is usually placed in a part of the brain that can tolerate this manipulation but rarely patients can develop weakness sensory or visual changes and speech difficulty. The proximal catheter tip is ideally positioned in the frontal horn of either lateral ventricle anterior to the foramen of monro away from the choroid plexus the proximal catheter exits through a burr hole to connect to a reservoir in the subcutaneous tissues through which csf may be. The catheter is placed through the skull and into one of the ventricles spaces of the brain where the cerebrospinal fluid csf collects.
When the shunt is placed the catheter must pass through normal brain tissue to reach the fluid cavity ventricle. Ventriculoperitoneal shunts consist of a valve and two tubes called catheters which drain the fluid. Ventriculoperitoneal vp shunts are a device used to shunt cerebrospinal fluid in the treatment of hydrocephalus.
The most common causes of shunt failure are malpositioning and obstruction of the ventricular catheter by debris or blood clothes. Ventriculoperitoneal shunt introduction ventriculoperitoneal vp shunt insertion is an operation to place a catheter into a brain ventricle to drain cerebrospinal fluid csf from the ventricular system. As the name suggests a catheter is placed with its tip in the ventricle.
The shunt consists of a catheter tube a valve and a reservoir. A ventriculoperitoneal shunt drains excess brain fluid reducing brain pressure to a safe level. The basic components of a csf shunt include a proximal catheter reservoir valve and distal catheter.
