I am seeking someone with knowledge or experience in R.F. ablation on a tumor that is encroaching on the middle hepatic vein. I have intrahepatic cholangiocarcinoma. I have had my right lobe taken away (resected) and there is reacurrance at the surgical site-middle vein. Also a new lesion in left lobe. I don't want to cook that vein. It is the main life giver to my liver. I do not have any Hep strain. Any insight would be truley appriciated.
