Oh wow...All I can say if it were me I would try. It sounds like this can be iffy since you just did this surgery ....and I know nothing about it...but IF you have the means to try to save him ...maybe try again ? Will he survive without this surgery ?
I can tell how much you love him
I don't envy you this decision and that's so heartbreaking. Bless his heart - he's just gorgeous.....all the best to you and you will be in my thoughts....
