RESUMEN
Vertebroplasty is a cost-effective procedure for the relief of pain in appropriately selected patients when performed by a skilled practitioner. The currently accepted indications and contraindications for vertebroplasty are reviewed. The techniques routinely used by the authors are presented, including a discussion of recognized complications. Recent controversy has highlighted weaknesses in the practice of technology evaluation, and more robust studies will be required to address these issues across the board in the future more scientifically than has been done in the past.

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.
