Hi there, If he is still having fevers and lethargic, I'd be worried that one of his grafts were infected. Sometimes, it takes many weeks or even months to get over a major surgery, but he should start to improve and not decline.  Blood cultures would be the first place to start, as if he has blood cultures that show infection, I'd be very worried that his arterial grafts were infected. If he has negative blood cultures, that is more reassuring.  If his incision is getting better, that's certainly a good sign. I would have a straight forward conversation with the surgeon who did the surgery and ask him why your husband hadn't fully recovered, and what his expectation for his recovery should be.  If he's not eating well and having pain, then there are certain things that can be due such as a nasogastric feeding tube, or perhaps even IV nutrition.  If he's having pain issues, then he should refer him to a chronic pain doctor.  And finally, if he's having fevers, I'd ask the surgeon if he has an infection of the grafts, and if he says no, I'd ask him where he thought the fevers were coming from this far out of surgery. In this case, it sounds like you really have to push your surgeon for answers.  No one will know the answers to these questions unless it's the surgeon who did the operation, who should be following him closely. I hope this is helpful. Please contact me if you have any further questions.
