Ventriculostomy Insertion

I just started my training in the Surgical ICU and have a bunch of questions. One that just came to me is, Does the insertion of a ventriculostomy drain have the potential of causing more brain injury? Does the catheter not go through brain parenchyma?
The biggest risks are infection and over drainage of CSF. The catheter does go through brain matter, yet typically the non-dominant hemisphere is used for insertion, unless contraindicated.

Thank you for your response. I just am having trouble grasping the fact that the catheter go through brain matter without causing any injury?

It causes injury but it's a benefit vs risk. The risk of death is greater than a few less brain cells. I ahd a neuro guy tell me once you loose more brain cells on a night of partying hearty.....

Okay, that makes sense! Thank you!

In premature infants with post-hemorrhagic hydrocephalus, over draining can cause the skull to collapse and cause more hemorrhaging.

...once had an intern pick up a VT drainage bag and hold it up to look at it...I lunged for the bag and he dropped it...what an idiot
