Vp Shunt Valve Types

The type of shunt system is named by the inflow and outflow locations e g.

Vp shunt valve types. A shunt consists of a ventricular catheter that is connected to a valve and then connected to a distal catheter. The time till median valve pressure adjustment was 2 9 years and 38 3 one year after vp shunt placement for the general sample in kaplan meier analysis. The programmable csf shunt valve has become an important tool in hydrocephalus treatment particularly in the nph population and in pediatric patients with complex hydrocephalus.

There is possibility to identify the opening pressure type of the valve in x ray low medium high pressure types of valves. The main differences between shunts are the type of valve used and whether the valve is programmable or not. A ventriculoperitoneal shunt vps is the most common type of implanted csf shunt system 1 2 an estimated 33 000 csf shunt placement procedures are performed in the us annu ally with most being vps 3 although vps placement is a commonly performed neuro surgical procedure and shunt valves and systems continue to.

Keep all products with magnets at least 2 inches away from the valve implant site your head. The article looks at the types procedure possible complications and tips for recovery. Too close to a magnet.

We have never noticed any malfunction in correlation to mri scans up to 1 5 tesla yet. A ventriculoperitoneal shunt is a medical device that surgeons use to treat hydrocephaly. The purpose of this study is to provide a single reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings.

A shunt valve is part of a ventriculoperitoneal vp shunt used in treating diseases such as hydrocephalus hydrocephalus is a condition involving an abnormal accumulation of cerebrospinal fluid csf the clear fluid which circulates around the brain and spinal cord inside the skull elevated amounts of fluid in the close confines of the skull can increase pressure inside the head and cause. The omni shunt system is a non programmable differential pressure valve. Be sure to follow the vp shunt manufac turer s guidelines for magnet precautions specific to your type of shunt.

This depends on the vp shunt model. Some general rules for many shunts are. If the proximal catheter is in the ventricle and the distal catheter is in the peritoneal cavity it is called a ventriculo peritoneal vp shunt table 1.
