Not sure about pancytopenia, but portal hypertension can lead to congestive splenomegaly and hypersplenism, which is most associated with thrombocytopenia and anemia. I wouldn't call it a stretch to say that it becomes pancytopenia when it also involves granulocytes, but it is definitely not the classic presentation for hypersplenism.
