Wow you're new at this. Welcome. I think.
A "revision" is the fancy codeword we use for surgery. A shunt revision is
literally where the surgeon "revises" the shunt so it functions again,
whether it is repaired, replaced, or both. It can be to treat any
reason.... infection, blockage, breakage (however rare) etc etc. typically,
by basic definition, any shunt operation except for the first one (although
it may be included if you wish).
