Figure 1
Figure 1 The figure shows a male, 43-year-old patient, 2 mo after splenectomy, with abdominal fullness for 6 d. He had thrombolysis through a transjugular intrahepatic portosystemic shunt (TIPS). A: Direct PV-SMV angiography showed extensive thrombosis in the PV and SMV. Contrast agent remained. No lateral branch angiogenesis (arrow); B: Mash and suck thrombi with intermittent injection of urokinase and heparin sodium. Repeated angiography 30 min after thrombolysis showed blood reperfusion in the PV-SMV and normal PV-SMV branches (arrow). Symptoms disappeared.

Figure 2 The figure shows a female, 22 year old patient who had abdominal pain for 17 d. A: A CT scan showed a high density of superior mesenteric vein thrombosis (characteristic of subacute thrombosis) (arrow); B: A Cobra catheter was inserted via the femoral artery into the superior mesenteric artery. Indirect angiography showed extensive thrombosis in the PV-SMV. Angiographic contrast agent remained (arrow); C: Indwelling catheters for 8 d. Angiography showed partial blood reperfusion in the PV-SMV. PV branches in the liver were intact (arrow). Symptoms were relieved.

Figure 3 A 24 year old male with abdominal pain for 8 d. A: The CT scan showed a low density SMV thrombosis (arrow); B: An enhanced CT scan still showed a low density of thrombosis (arrow). This fulfilled the symptoms and signs of acute thrombosis; C: An extended Cobra catheter was introduced into the superior mesenteric artery via the radial artery. The indirect angiography shows extensive thrombosis in the PV-SMV without lateral branch angiogenesis (arrow); D: Indwelling catheters for 10 d. The indirect angiography showed that the lateral vessels of the PV-SMV had significantly increased (arrow). Symptoms were relieved.
