An overview of vascular closure devices: what every radiologist should know.

Haemostatic devices can be categorised according to their mechanism of action into three main types; namely pressure devices, topical haemostatic pads and vascular closure devices (VCD). Of these three categories, it is the development of VCDs that revolutionised management of endovascular procedures. Currently available VCDs fall into three major classes, those that use a collagen plug, those that use clips and those that perform suture closure at the arteriotomy site. This article provides a comprehensive review of the all three classes with examples of commercially available devices. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.
