My sister 40 yo w/congential fibrosis of liver, renal failure, hep c. In the past 2 months has had increased hepatic encephalopathy. She is on the tx list and we have been called many times but due to a portorenal shunt (at age 8), and her very small size (4'10"; 95 lbs.), size has been a major issue. She has been in/out of the hospital every couple of weeks for last month or so due to low blood pressure or escalated ammonia levels. Can you give me an idea of what we can expect from here and maybe best/worst case scenarios of life expectancy.
