Mike, I hope all be fine.
Your wife accept clots thinning drugs?
Follow her closely, if you suddenly see start attacks,
as if the person is choking. In this case,
immediately call an ambulance, immediately,
and for an examination of the shunt via MRT.
If a person as if suffocating, then it may be clogged shunt.
In the past year my girlfriend's mother died, because of this
(75 years old). Doctors are not identified during shunt
blockage symptoms. After bypass surgery this happened across 4 months.
Accept my prayers.
And be very watchful.
