Portal venography results from different modalities used at admission and after thrombolysis. A, B: Transverse and coronal reformation of magnetic resonance imaging portal venography showed hypointensity in the superior mesenteric venous (SMV) (white arrow) at admission; C, D, F, G: Transverse and coronal reformation on three-dimensional helical computed tomography (CT) portal venography showed a filling defect and refilling in the SMV (white arrow) at admission and after thrombolysis; contrast enhanced CT image showed bowel dilatation, bowel wall thickening, and peritoneal effusion secondary to acute superior mesenteric vein thrombosis; E, H: Portal venography in digital subtraction angiography showed a filling defect and refilling of contrast medium in the trunk of the SMV at admission and after thrombolysis.
