Table 5 summarizes the mean velocities and ICA to CCA ratios for = 30 to < 50%, = 50 to < 70%, and = 70 to 99% in-stent restenosis, based on CT angiography. ROC Curves: Sensitivity and Specificity ...

There has been an ongoing debate regarding which duplex ultrasound (DUS) criteria to use to determine the rate of in-stent restenosis. This prospective study revisits DUS criteria for determining ...

Fractures and breakages of the helix on the Rotarex system has led to 30 serious injuries, four deaths, and 115 interventions ...

Boston Scientific (NYSE:BSX) said it has received FDA approval for its Agent Drug-Coated Balloon for the treatment of coronary in-stent restenosis, the narrowing of a stented blood vessel due to ...

These studies suggest that the rate of restenosis and the proportion of patients in need of repeat revascularization may indeed be increased with the use of long stents and multiple areas of stent ...

Overall, the researchers were able to convincingly show that stenting for vertebral artery stenosis could be performed safely and effectively, 1 with a rate of in-stent restenosis lower than that ...

However, traditional metal stents may cause restenosis—a re-narrowing of the artery—due to excessive smooth muscle cell proliferation one month after implantation. Drug-eluting stents are ...
