Abstract

Self-expanding nitinol stents are routinely used to treat left common iliac vein compression in patients with May-Thurner syndrome. On occasion these stents do not provide adequate radial force to achieve a sufficient iliac lumen. If symptoms persist and persistent iliac vein compression is noted then balloon-expandable stents may be used to provide buttressing support at the compression site.  We present a case where the buttressing balloon-expandable stent is crushed and subsequently removed percutaneously prior to placement of a high radial force self-expanding stent at the compressive site.

A 38-year-old woman with May-Thurner syndrome underwent left common iliac vein self-expanding nitinol stent placement. Thirteen months later, she had recurrent symptoms due to collapse/compression of the stent (Fig. 1a) at the May-Thurner lesion. A buttressing balloon-expandable stent was placed (Fig. 1b) with symptom resolution. She again returned, two months later with recurrent left leg pain and swelling. Imaging revealed the balloon-expandable stent crushed at the May-Thurner compression site (Fig. 1c). Given the high likelihood of recurrent stent crushing with simple re-dilation of the balloon-expandable stent, plan was made to attempt stent removal.
