Vp Shunt Trajectory

Vp shunt trajectory. There is a myriad of reasons as to why a vp shunt should be placed. Data regarding the best trajectory for the frazier point are. Early studies on ventriculoperitoneal shunt malfunctions demonstrated that proximal catheter obstruction was the most common cause.

Three shunts types are mainly used to shunt csf. The aim of this technical report is to report a new method for ventriculoperitoneal vp shunt placement by determining the angle and distance of the proximal shunt catheter trajectory in the coronal plane using a simple modification of a standard coronal mri. By far the commonest are vp shunts.

Nine patients who had failed conservative management were included. If new shunt pop endoscope through catheter for visualization. All patients had intractable headaches and five patients also experienced visual compromise.

They can be categorized into congenital or acquired causes. If a vp shunt placement was considered in an infant a programmable shunt with a high pressure valve setting was placed to keep the ventricles intentionally open. The postoperative follow up period ranged from 6 to 110 months.

Four adults who had undergone stereotactic brain magnetic resonance mr imaging and had normal ventricles and 7 prospectively recruited adult patients with acute hydrocephalus were selected for inclusion in this study. Ventriculoperitoneal vp ventriculopleural vpl and ventriculoatrial va. Physicians treating patients with a vpl shunt must be aware of specific possible complications from these devices.

The authors present their experience with stereotactic placement of vp shunts in a small series of patients with iih. Vpl shunts have a higher failure rate than do vp shunts and are generally placed only if the peritoneum or vascular space is unsuitable. Insertion of vp shunts at the parieto occipiatal area enoh s point is safe and easy with acceptable short term complication rates and outcome.
