Intravascular sonography, has an advantage over angiography because it provides images from within the vessel, has greater resolution without having to penetrate the extravascular soft tissues, and provides 3D assessments (20). Because of its higher spatial resolution and the fact that it enables analysis of the insides of vessel walls, IVUS provides a more reproducible and accurate measurement of disease severity than angiography (10). In this study we used IVUS as a complementary tool during SV in order to delineate better details of endoluminal structural abnormalities.
