Vascular stent Implants cardiovasculaires? Significant reduction in luminal diameter at any point along the length of the stent when compared to the post-procedural reference diameter. In the selection of the equipment used for this evaluation, consideration should be given to this variability. Might be due to twisting or kinking of the stent, failure of the stent to fully open, dissection or any other cause.
