U have not provided enough details of ur husband's serology. The blood reports would ve been helpful to make an inference.
Even though surgical outcomes are always obscure it is still a chance to be taken always. Current days post op patients are treated very nicely but still casualties happen. U cannot say anything surely.
With AVN the quality of life of ur husband will always be poor. So if the doctors assure you to go with surgery go with it. Elective surgery doesn't means patient gonna die but it's a little more risky than others.
Procrit is a necessary drug for kidney patients and u shall take it and not discontinue. Ur complications are not due to this injection.
Additionally why are his doctors going with two antivirals. Baraclude is sufficient enough to handle hbv.
I know almost nothing about usage of these medicines in patients undergoing surgery. Even so, I would add that going off oral Hep B medication (unless specific treatment end-points have been reached) always risky. All oral Hep B medications come with the warning that HBV DNA levels shoot up if you go off meds altogether. I see that both Entecavir and Adefovir recommend a reduced dosage, and don't recommend stopping, it even if the patient is on dialysis.
Not qualified to answer these questions.
OK, so how can he go ahead with this surgery? There is going to come a time where he can be looking at emergency surgery, we know this. I want him to go to Boston, for another opinion.
"he is at a increase rate of something going wrong with this surgery because of his other health problems is this true?"
--The question is so general the answer has to be Yes.
Hepsera affects kidney more than Baraclude.
