Hi, Seth, and welcome to the forum. I'm so sorry that your father is battling this disease. I know how concerned you must be about him.
The only thing I know is that the Mayo Clinic DOES take other factors into consideration when evaluating and listing for a liver. There are conditions that will override a MELD score, if they feel that the patient in question is going to die within a week if he doesn't get a liver. I'm not sure if other transplant centers have the same exception, or if they go strictly by the MELD score, which (as you know) can go up and down while the patient's symptoms indicate that he is sicker than the MELD score shows. It is very frustrating, I know, as I've seen many spouses and loved ones here battle with the same things you are.
Since today is a holiday, we may not get many posts. But check back over the weekend, and I'm sure you will get some input from others.
