Application of intraluminal ultrasound imaging to vascular stenting.

Over the past few years catheter-based intraluminal ultrasound (IVUS) has emerged as a promising and imaginative technique which can significantly extend our understanding of atherosclerotic lesions both before and following interventions. In relation to stent implantation intravascular ultrasound appears well suited as an imaging modality--providing information as to lumen shape lesion surface and topography, as well as wall composition. To this end arteriography is unable to provide such detailed information. The purpose of this review is to outline the characteristics of stents and endoluminal support devices, currently under investigation, and the role of ultravascular ultrasound in this respect.
