a An overview of the postoperative clinical course. b A time series showing multidetector-row computed tomography findings, the course of treatment, and the changes in serum AST and ALT levels. b-1 Before the anticoagulation therapy. Yellow arrowheads show thrombotic occlusion of the LHV. b-2 After the anticoagulation therapy. Yellow arrowheads show improvement in blood flow of the LHV. b-3 Before the first endovascular intervention. Yellow arrowheads show thrombotic occlusion of the LHV. Hepatic congestion in the drainage area of the occluded LHV can be identified. b-4 After the first endovascular intervention. Yellow arrowheads show improvement of blood flow of the LHV. b-5 Before the second endovascular intervention. Contrast effects of the LHV were not observed. b-6 Before the third endovascular intervention. Contrast effects of the LHV were not observed. b-7 After the third endovascular intervention. Yellow arrowheads show improvement of blood flow of the LHV. POM, postoperative month; LHV, left hepatic vein; AST, aspartate aminotransferase; ALT, alanine aminotransferase
