Reconstructing the portal vein through a posterior pancreatic tunnel: New choice for portal vein thrombosis during liver transplantation

Figure 2 Embolization of large splenorenal shunt under digital subtraction angiography alleviates portal vein insufficiency after liver transplantation. A: Preoperative three-dimensional (3D) visualization model showed a slender portal vein (arrow) and obvious splenorenal shunt varices (*); B: Postoperative 3D visualization model on day 3 showed a normal portal vein shape and unobstructed blood flow (arrow), and splenorenal shunt varicosity was reduced (*); C: Postoperative 3D visualization model (at 3 wk) showed portal vein stenosis in the initial segment (arrow), and color Doppler ultrasound examination indicated insufficient portal venous blood supply; D: Percutaneous and transhepatic splenic venography showed that most splenic venous flow drained into the inferior vena cava through the splenorenal shunt, but did not drain into the portal vein (arrow); E: After embolization of the splenorenal shunt (arrow), angiography showed that blood flow was mainly present into the portal vein; F: 3D visualization model 1 wk after the vascular intervention showed unobstructed portal vein flow (arrow), and the splenorenal shunt was no longer visible.
