Fig. 2. Post-treatment ultrasonography (US) and axial view of abdominal computed tomography (CT) images. (A) After 2 weeks of anticoagulant therapy, the US image showed no flow signal at the right proximal portal vein using super microvascular imaging (SMI) (arrow). (B) After 3 weeks of anticoagulant therapy, the US image showed a restored portal vein flow signal on SMI (arrow). (C) After 1 month of anticoagulant therapy, the axial portal phase CT image showed recanalization of the right portal vein (arrow), but remaining preexisting chronic thrombus. (D) At 6 months after the end of anticoagulant therapy, the axial portal phase CT image showed improvements of partial thrombosis (arrow), recanalized left portal vein (dotted arrow), and decreased ascites. (E) At 6 months after the end of anticoagulation therapy, axial portal phase CT image showed cavernous transformation (arrow).
