Axial computed tomography images in this patient. A – On day 2 of admission, CT images demonstrated occlusive thrombosis within the right portal vein (RPV) (solid black arrow) and superior mesenteric vein (SMV) (solid red arrow) and mesenteric venous gas (dotted red arrow). B – On day 8 of admission, CT images demonstrated partially recanalized RPV (solid black arrow), but SMV (solid red arrow) thrombosis remained occluded and mesenteric venous gas persisted (dotted red arrow). C – On day 31 of admission, CT images demonstrated that SMV (solid red arrow) thrombosis was slightly improved, and the mesenteric venous gas disappeared (dotted red arrow). D – After 3-month anticoagulation with rivaroxaban, CT images demonstrated completely recanalized SMV (solid red arrow) without mesenteric venous gas (dotted red arrow)
