A Less Common Complication of Hydrocephalus

I've had a stomach ache for 18 months. My neurosurgeon says either of the distal catheters may be causing the pain.  The new one  (almost two years old) or the old one almost thirty years old.   Once he figures out which one is causing the pain it will need to be trimmed.  If it's the old one he'll need the assistance of another surgeon to disentangle the old catheter.

The good news is the old shunt lasted 27 1/2 years.  The bad news is the complications of the remaining, aging catheter will be with me forever.  This may be just a hiccup, or this may be just the beginning.
