Hi. I have had a kidney transplant since July 2000. Both the kidney and I are keeping on keeping on (I hope). Perhaps I missed it, but has your Mother's liver failed, or is it failing? Although not a doctor, if the liver has failed then the time window in which to do a transplant is very limited. One ironclad transplant rule, at least for kidney transplants, is that a patient's body mass index (BMI) must be below 39 (I believe). BMI is calculated by using the patient's weight and height. God bless you and yours at this time.
