Figure 1 Twenty-nine years old girl with Budd-Chiari syndrome and leiden factor V positive for heterozygote. A: Gadolinium-enhanced T1-weighted magnetic resonance image (MRI) obtained during arterial phase. Hyperintense structures represent portal venules, which are visible because of postsinusoidal portal hypertension; B: T2-weighted MRI shows hyperintensity ascites and splenomegaly; C: Using a Rösch-Uchida transjugular liver access set, a small collateral hepatic vein branch was accessed, the portal vein was punctured (D), and wire access into the superior mesenteric vein was achieved. A 10-mm diameter, 6-cm long Viatorr stent (W. L. Gore and Associates, Flagstaff, AZ, United States) was deployed, extending from the right portal vein to the inferior vena cava (E, F).

Figure 2 Access technique. A: Initial inferior vein cava (IVC) venography depicting the origin of the obstructed right hepatic vein (arrowhead); B: Colapinto stylet positioning prior direct puncture of the IVC at the level of the origin of the thrombosed right hepatic vein (arrowhead), just below the diaphragm. Note the tip of the sheath within the right atrium (arrow); C: The Colapinto needle is turned anteriorly, parallel to the spine and access obtained at the main right portal branch; D: Final result after the deployment of 2 stent grafts.

Shunt created 9 years before, using a dedicated stent graft (VIATORR® TIPS Endoprosthesis; GORE®, United States), in a patient with Budd-Chiari syndrome due to primary thrombocythemia. A: Computed tomography image demonstrating a complete occlusion of the intra-parenchymal segment of the stent graft; B: Digital subtraction angiography (DSA) following lesion crossing, confirming the occlusion; C: Final DSA demonstrating flow restoration following deployment of a 10 mm × 80 mm stent graft (Fluency™; BD, United States).
