I fell at the first double negative ( it isnt very well written)
There seems to be paucity of evidence on when one can fly following neurosurgery. With a recent paper based on surgeon's preference, only 5 out of 66 surgeons were not against flying after neurosurgery.
not against flying - o god my brain hurts
so the idea seems to be
you cant fly around the world for the best neuro surgical treatment because it might go 'foop'! on the way
and yet people do.
and if you do .... you are stuck here
and yet people come back
oh and if you have survived 12 y without a rebleed
then you have a 90% chance of going 4 y without a rebleed
someone quantised "the longer you live - the longer you live" and came up with the rule of thirds
( if a house has stood for 99 y then it is likely to last another 33 y)
I would do what you want quite honestly
