Hi, Jan, and welcome to the forum. I have hep C and have also had liver cancer. I was treated at Mayo Jacksonville with chemoembolization, TheraSphere, and finally removal of the rt. lobe of my liver, where the tumor was taking up most of the lobe, in May '07.
Has your father's liver cancer metastasized? Mine had--to the inferior vena cava--but the TheraSphere (microscopic radioactive beads injected into the tumor) shrunk it back into the tumor. Therefore, they were able to operate.
I have never had encephalopathy, so your dad's disease must be more advanced. Although I had ascites and edema of the lower extremities, I was never drained. I was put on Lasix and Aldactone, and still take them, but at a lower dose. I also monitor my salt intake.
I'm sure you will find a lot of information and support on this forum.
Hugs,
Connie
