intravascular ultrasonography

intravascular ultrasonography

The use of ultrasound imaging by means of a transducer within a blood vessel. This has become possible by the development of ultrasound probe catheters small enough to be inserted into a coronary artery and other peripheral arteries. The method produces detailed images of the interior walls of arteries and is especially useful in assessing plaque morphology and volume in cases of ATHEROSCLEROSIS. The method can also be used for STENT placement and the assessment of plaque regression during statin therapy.

To be sure, that there was no dissection, but only in-situ thrombus formation intravascular ultrasonography (IVUS) with CromoFlo was performed with Volcano Eagle Eye Gold IVUS catheter (Fig.
Intravascular ultrasonography performed 12 months posttransplant found the incidence of vasculopathy was lower for both everolimus groups-35.
Our findings that everolimus significantly reduced the frequency and severity of vasculopathy, as measured by intravascular ultrasonography, offers a note of cautious optimism with respect to the control of this disorder.
The primary endpoint was the change in average intimal index (plaque area divided by vessel area) measured by intravascular ultrasonography (IVUS).
The bigger question concerns the potential role of newly available radiofrequency intravascular ultrasonography (RF IVUS) in early assessment of patients with ACS.
For example intravascular ultrasonography would give us more detailed information about the severity, as well as the nature-complexity of the coronary lesions.
We believe in cases of MB when invasive intervention is the only choice of treatment, intravascular ultrasonography (IVUS) should be performed to detect any accompanying atherosclerotic disease.
The existence of a MB was confirmed with intravascular ultrasonography (IVUS), which also revealed a plaque creating 80% stenosis just distal to the bridge (Fig.
