Acute extensive portal and mesenteric venous thrombosis after splenectomy: Treated by interventional thrombolysis with transjugular approach

Figure 3 Case 3: A 38-year-old woman with abdominal pain, nausea, distension, and vomiting for 3 d. She had undergone splenectomy 2 wk previously. A: Selected axial image from before open splenectomy contrast-enhanced CT shows splenomegaly (arrows) and patent portal vein (curved arrow); B: Selected axial image from admission contrast-enhanced CT, on postoperative day 14, shows extensive thrombus within the PV (arrows); C: Pre-treatment direct venography via transjugular approach access to the portal vein showing extensive PV (arrows) and SMV (curved arrows) thrombosis, without collateral drainage; D: Follow-up direct portal venography via the infusion catheter (curved arrow), obtained 5 d after the catheter infusion of thrombolytics, shows patent PV and SMV with residual thrombosis within the intrahepatic portal venous branches (arrow).
