Vp Shunt Tip Location

The catheter is placed through the skull and into one of the ventricles spaces of the brain where the cerebrospinal fluid csf collects.

Vp shunt tip location. Relationship of the location of the ventricular catheter tip and function of the ventriculoperitoneal shunt article in journal of clinical neuroscience 20 1 99 101 january 2013 with 56 reads. The relationship between the location of the ventricular catheter tip and vp shunt function was analyzed in 52 patients. Ap radiograph of the skull shows a discontinuity between the tip of the vp shunt and the rest of the vp shunt.

Ventriculoperitoneal shunt introduction ventriculoperitoneal vp shunt insertion is an operation to place a. The long term maintenance of ventriculoperitoneal vp shunt function depends on the correct placement of the catheter tip in the lateral ventricle. The external portion of the catheter is connected to a valve that regulates the flow of csf based on a preset pressure.

Correlation between ventricular catheter tip location and function of vp shunt table 1 shows the number of patients according to catheter tip location and shunt function. Cases of ventriculoperitoneal shunt malfunction malposition misposition misplacement ap and lateral radiographs of the abdomen shows the distal portion of the vp shunt to be broken into multiple fragments. The incidence of ventriculoperitoneal shunt failure ranges from 25 to 40 at 1 year and 63 to 70 at 10 years failure rates with ventriculoatrial and ventriculopleural shunts are slightly higher patient presentation varies depending on patient age as well as the cause and acuity of failure symptoms with the highest positive predictive value include nausea and vomiting and decreased.

The shunt consists of a catheter tube a valve and a reservoir. Vp shunt function was well maintained in 14 patients 26 9 of whom 13 were in groups a or b demonstrating an odds ratio or of 17 875 p 0 05 table 2 a. As the name suggests a catheter is placed with its tip in the ventricle.

The knowledge of the relationship between ventricular catheter tip position etiology of hydrocephalus and patient s age with shunt malfunction may be useful to avoid shunt failure. Recovery most patients are discharged within 2 5 days after a straightforward vp. Ventriculoperitoneal vp shunts are a device used to shunt cerebrospinal fluid in the treatment of hydrocephalus.
