Example of mispositioned TIPS. (a) C-shaped TIPS (white arrow), results of coaxial positioning of a second stent graft in order to adequately cover the intraparenchymal and hepatic vein tracts (white dot and arrowhead). (b) Placement of a new straight TIPS covering the junction of the HV with the IVC (white dot); the previous short and curved TIPS (white arrow) developed a complete thrombosis despite the deployment of a coaxial longer stent graft (white arrowhead). (c) To cover the entire length of the HV beyond the junction with the IVC, a new coaxial stent graft was deployed inside the original TIPS. The white bracket indicates the distance between the original and the coaxial stent graft distal markers (white arrowheads). HV, hepatic vein; IVC, inferior vena cava, TIPS, transjugular intrahepatic portosystemic shunt.
