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 ...

Repeated Doppler ultrasound showed no flow through the SMA with concomitant critical TC stenosis ... Control Doppler scan confirmed patency and proper blood flow across the stent. The presented case ...

Optical coherence tomography (OCT) is non-inferior to intravascular ultrasound (IVUS ... to assess target lesion characteristics, optimize stent implantation and minimize stent-related problems.
