I had a brain shunt installed in 1977 when I was 15. I had a motorcycle accident that resulted in hydrocephalus. I have not experienced any problems, but I am worried that something may happen due to the age of the shunt. Has anyone had a shunt for such a long period of time without suffering any problems? Has anyone experienced problems with an aged shunt after such a long period of time? My doctor told me that it may become brittle at some point. Has anyone ever had one get brittle? After how long? Was the shunt replaced? Any information regarding aging and operation of the shunt would be appreciated.
