Vp Shunt Vs Evd

Endoscopic third ventriculostomy etv.

Vp shunt vs evd. Zunt in handbook of clinical neurology 2010. Currently there is no established standard regarding the ideal number of external ventricular drain evd clamp trials performed before ventriculoperitoneal vp shunt insertion following nontraumatic subarachnoid hemorrhage sah. If the hydrocephalus is not improved or gets worse after the evd has been clamped the patient will require placement of a permanent ventriculoperitoneal vp shunt.

The external ventricular drain evd catheter is an alternative method for monitoring and controlling elevated icp. As the name suggests the catheter that is inserted diverts the cerebrospinal fluid csf from the lateral ventricles of the brain into the peritoneum. A shunt is a long plastic tube that lets fluid drain from the brain.

In this study the authors aimed to evaluate this relationship. There was no increase in delayed vp shunt placement at 3 months 9 3 vs 8 6 univariate p 0 41. What is an external shunt.

Although cns infection rates as high as 27 have been reported in patients undergoing evd placement highest rates of infection occurred in patients who had an evd in place for an average of 8 1. Shunt timing and length of stay. To analyze the effect of vs timing following evd we compared those undergoing vs in the first 2 weeks with those undergoing vs later than 2 weeks.

The intermittent rapid evd approach was also associated with a shorter mean evd duration 10 2 vs 15 6 days p 0 001 shorter icu los 14 2 vs 16 9 days p 0 001 shorter hospital los 18 2 vs 23 7 days p 0 0001 and lower incidence of a nonfunctioning evd 15 vs 30 or 0 29 p 0 006. Evd external ventricular drain.

Doctors use shunts to relieve pressure on the brain. Treatment in which an endoscope is used to puncture a membrane in the floor of the third ventricle creating a pathway for csf flow within the cavities in the brain. This pressure is usually caused by a condition called hydrocephalus.
