Figure 3 Surgical protocol and procedures. A: The parent magnet was guided to the target position of the inferior vena cava (IVC) by the wire fixed to one end and the catheter; B: The daughter magnet was advanced to the anastomosis position of the portal vein (PV) by the guide wire and catheter through the incision on the splenic vein; C: Position of the magnets and the wire after the first surgery; D: The magnets were pulled out of the body by the wire fixed to the parent magnet and the portal-IVC shunt was set up.
