Comparison of visibility for four self-expanding nitinol bare stents in vitro

Abstract

The SMART stent had the best overall performance. In the presence of bone overlap, all self-expanding nitinol stents had poor results. Increased pulsing frequency did not improve ODR or SRS but did increase the DAP. Use of digital magnification modes had no effect on DAP increasing ODR and SRS.

Mechanical thrombectomy with the Trevo ProVue device in ischemic stroke patients: does improved visibility translate into a clinical benefit?

“…While intensive work has been done by X-ray equipment manufacturers to enhance stent visibility in other fields,38–40 nitinol stents with overlying bony structures usually remain almost invisible 41. Recently, the potential clinical benefit of conscious sedation over general anesthesia for neurothrombectomy has been emphasized 21 22 42 43.…”

Method for Fabricating Miniaturized NiTi Self-Expandable Thin Film Devices with Increased Radiopacity

“…Approaches to increase radiopacity have been manifold in the last two decades: the optimization of X-ray imaging parameters for scanning Nitinol devices has been investigated to begin with, in particular combinations of pulse-dose and frequency for achieving improved image quality. However, no significant improvements of objective or subjective stent detection rate or visibility were obtained [2]. Hence, the material itself requires adjustments.…”
