I have been trying to look for informartion regarding fixed pressure valve indications. There are mainly low, middle and high fixed pressure valves. What are the indications for each one? I understand you need to know about the physiologyand dynamics of CSF. Please do not reply without any reference. I need scientic facts only.

Thanks

Is Vancouver a suitable reference style for you my liege?[1]

Every patient has a csf pressure and flow rate that is ideal for them. The difficult thing is figuring out that pressure and flow before surgery, which is the major value of an adjustable pressure valve because you can try several options. My personal feeling is unless someone had an evd then the safest course of action is an adjustable valve and on the first revision you can switch to fixed pressure once you have found their ideal setting.

I have not seen a fixed pressure valve implantation at my institution yet....

A pubmed search would likely do you some good.

I'm a little lazy at the moment, but in my folder for papers I'm certain I have a review of the various programmable and fixed pressure valves and their, relative, indication.
