CSF Shunt Summary

HIDE
PrevNext

0:01

So in the final scenario of status post ventricular

0:04

peritoneal shunt with new lethargy or new mental

0:08

status changes, I've shown you several examples.

0:11

We saw a case where there was shunt malfunction with

0:14

secondary obstruction, and the ventricles enlarged.

0:17

We saw a case where there was a CSF collection which enlarged at

0:22

the setting of the reservoir, not necessarily at the

0:26

distal end in the peritoneum because, frankly, this is

0:28

not part of the central nervous system or neuroimaging.

0:31

But we also saw an example of a patient who had over-

0:35

drainage, which led to bilateral subdural hygroma

0:40

formation because of the decreased pressure in

0:44

the ventricular system compared to the

0:47

pressure outside the brain in the subdural space.

0:51

All of these are issues that may present themselves

0:55

when you are dealing with pediatric patients

0:58

through the emergency room who have been shunted.
