Bridging Stent Placement in Vena Cava Syndrome With Tumor Thrombotic Extension in the Right Atrium

Venous stent placement of symptomatic occlusion of the superior and inferior vena cava is considered the treatment of choice in malignant disease because this technique can restore patency and achieve a relief of symptoms. However, tumor thrombus extension into the right atrium harbors the potential risk of stent migration and perforation. One strategy to avoid this potential life-threatening complication could be the placement of a bridging stent from the superior vena cava-to-inferior vena cava. This case reports describes the superior vena cava-to-inferior vena cava bridging stent technique in 2 patients with malignant occlusion of the superior and inferior vena cava. Special considerations such as technical details of the devices and potential complications are discussed.
