Levels of aspartate aminotransferase (AST), total bilirubin (T-bil), and platelet (PLT) counts in peripheral blood. (A) Level of AST was highest on postoperative day (POD) 1 (4500 IU/L), and it then decreased gradually. On POD 14, thrombosis of the portal vein in the remnant liver occurred, and the level of AST again increased (479 IU/L), after which the level of AST was stable, and there was no increase after the closure of the arterio-portal shunt (APS); (B) Level of T-bil was highest on POD 20 (15.9 mg/dl), after which it decreased gradually, and did not increase after the closure of APS. (C) Platelet count in the peripheral blood was highest on POD 20 (12.2 × 104/μL), after which it decreased gradually because of portal hypertension and splenomegaly; it was less than 5.0 × 104/μL by POD 67. After closure of the APS on POD 73, the PLT count increased gradually and by POD 85 it was 8.5 × 104/μL.
