Cobalt Chromium or Stainless Steel Balloon-Expandable Bare Metal Stents for Iliac Occlusive Disease?

Stents with a thin-strut structure improve the flexibility and deliverability. The lower profile also increases the applicability lowering the risk of vascular access complications. In this study newer-generation cobalt chromium balloon-expandable stent did not confer advantages over stainless steel bare metal stent. On contrary, the technical success was inferior to stainless steel stents as longitudinal deformation or dislocation of the Dynetic-35 occurred. Therefore, enhanced attention should be given passing a Cobalt chromium stent with wires, catheters or sheaths to avoid stent deformation.
