Randomized comparison of effects of suture-based and collagen-based vascular closure devices on post-procedural leg perfusion

Background Vascular closure devices (VCD) are well established to facilitate hemostasis after cardiac catheterization procedures. However, impairment of flow due to the reduction of femoral artery diameter remains a major concern. The present study aims to evaluate leg perfusion before and after application of collagen- and suture-based vascular closure devices.
