Superior vena cava-to-inferior vena cava bridging stent placement was described in 2 patients with malignant vena cava occlusion to avoid stent migration and perforation.
Case Report (n=2)
A bridging stent from the superior to inferior vena cava may be a feasible strategy to avoid stent migration and perforation in patients with malignant vena cava occlusion and tumor thrombus extension into 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.
Zander et al. (Mon,) conducted a case report in Malignant occlusion of the superior and inferior vena cava with tumor thrombotic extension in the right atrium (n=2). Superior vena cava-to-inferior vena cava bridging stent placement was evaluated. Superior vena cava-to-inferior vena cava bridging stent placement was described in 2 patients with malignant vena cava occlusion to avoid stent migration and perforation.
