Budd Chiari syndrome (BCS) results from hepatic outflow obstruction. Endovascular management to restore venous patency, including inferior vena cava (IVC) angioplasty with stenting, and transjugular intrahepatic shunt (TIPS) placement to decompress liver congestion, have become standard of care. Herein, we describe a patient with BCS requiring liver transplantation and the surgical technique of suprahepatic IVC anastomosis including thoracic extension of an IVC stent with a review of the relevant literature. A 29-year-old female with BCS due to polycythemia vera, who had been previously managed with TIPS and IVC stent placement, was taken for liver transplantation. Preoperative imaging confirmed stent extension into the thoracic IVC and the stent was unable to be removed intraoperatively. The thoracic IVC was clamped through the diaphragm at the level of the right atrium and the stent was left in place and incorporated within the suprahepatic anastomosis with good vascular outcome at one year follow up. Diligent preoperative preparation is essential with adequate imaging and cardiac surgical consultation in patients with malpositioned stents. Review of the literature shows four cases in which performing the suprahepatic anastomosis including an embedded stent is a viable alternative that allows for avoidance of a thoracotomy.
