Hi and welcome to the Chiari Malformation forum.
Budd Chiari and Chiari Malformation are two different conditions, your's is a liver issue while the one we discus here is a brain related condition.....You may want to check out a Liver Conditions/disease forum for others with your same BCS.
I would like to add, we do have a similar issue with Drs not really knowing what our Chiari is or how it affects us and or how to treat us effectively.
