Ultrasound in Peripheral Arterial Atherosclerotic Disease

In presence of peripheral arterial atherosclerotic disease, it is necessary to detect and describe the stenosis, the occlusions and the aneurysms.

In the hemodynamic stenosis, although duplex ultrasound includes images, the primary parameter is the peak systolic velocity: a high-velocity systolic and diastolic signal is revealed over the stenotic segment.

The peripheral arterial occlusion is characterized by the absence of the color and of the spectral Doppler waveform within the arterial segment occluded. The waveform recorded distal to the occlusion is monophasic, in the absence of reversed component.

The ultrasound imaging is the initial non-invasive diagnostic modality used to study the peripheral artery aneurysms: the echocolor Doppler may demonstrate swirling flow within the aneurysm or no color flow if it is completely occluded. 

In this lesson the echocolor Doppler characteristics of the peripheral arterial atherosclerotic disease are presented.
