Two years ago today my youngest son was recovering from his second invasive brain surgery. This time, to place a ventriculoperitoneal (VP) shunt into the right rear side behind his ear, to constantly drain cerebrospinal fluid (CSF) from the ventricles in the brain where it is produced, into his abdominal cavity via a catheter tube running internally down his neck. This device, though far from perfect in its design, with something like a 50% fail rate in the first year or two after placement, is a life-saver for children with hydrocephalus. It stops the fluid, which has trouble draining naturally, from building to the point where it squashes the brain against the skull, leading to brain damage and eventually (if left untreated) death.
Way back then, when he was just three months old, we were amazed at how resilient he was and how he had bounced back from his first brain surgery like a champion, but there were so many unknowns about how much his conditions would impact him as he grew and developed.
