Management of central venous stent migration in a patient with a permanent inferior vena cava filter.
Stent embolization is a rare complication in the treatment of central venous stenoses in patients receiving long-term hemodialysis. The authors report a case of nitinol stent embolization into the right atrium in which the stent could not be repositioned across an indwelling permanent inferior vena cava (IVC) filter. The migrated stent was managed by advancing the stent to the superior margin of the IVC filter and then deploying a second suprarenal IVC filter to prevent repeat embolization.
