Confirmation of no Common Femoral Artery Stenosis Following Percutaneous EVAR

Excerpt

We thank White et al. [1] for their comments on the findings of our paper [2], demonstrating the long-term outcomes of percutaneous EVAR. Given the aims of the study, we believe the design of comparing two time points post-intervention (30 days and longest follow-up scan) was best suited to investigate the long-term evolution of accessed groins. White et al.’s comments that the review of pre-procedure scans would be helpful to their understanding. We had previously taken the view that suture-mediated closure devices had established data on their short-term safety and efficacy and had not set about confirming this. However, to further inform readers we have since analysed changes at these three time points—pre-procedure, 30 days post-procedure (short term) and latest follow-up scan (long term). As per our original study [2], paired T test and Wilcoxon matched pairs signed-rank test was used to assess the significance of changes in vessel diameter and calcification, respectively. …
