Peripheral vascular interventions conventionally have been performed using angiography for diagnosis and guidance of devices. Newer interventions, particularly those emphasizing endovascular repair of vascular lesions, have shown encouraging initial results, although a considerable number of procedures are still plagued by immediate and late complications. Imaging modalities, including contrast computed tomographic scanning, magnetic resonance angiography and intravascular ultrasound are improving diagnostic and interventional accuracy.
Intravascular ultrasound is an imaging method that adds considerable information and precision to interventional procedures. This method has been shown to be complementary to both angiography and angioscopy in its ability to image the entire circumference of vessel lumen and wall, as well as the morphologic components of the atherosclerotic lesions, providing unique in vivo information.
