Pressures trump tracings. This means that if the pressures are normal but the tracings are not, believe the pressures. However, in general these two pieces of information should align. So before scratching off a discrepancy, think. A decrease of 20 mmHg in pressure between adjacent segments denotes disease The human body is symmetrical.

PVR interpretation involves analyzing both the amplitude and contour tracings to recognize specific patterns to identify areas of stenosis in the affected extremity ( Figure 5 ). Tracings show the changes of volume within an extremity during arterial pulsation.

A PVR is a graph of the pulsatile change in limb volume from blood flow using constant standard pressure. Modern vascular laboratories acquire these tracings using the same pressure cuffs used for segmental limb pressure measurement. Normal PVRs consist of a rapid upstroke with a sharp peak, a dicrotic notch, and a concave-up late diastolic component.

PVR tracings are moderately abnormal throughout on the left. Segmental pressures and ABIs are in the moderate range. This study suggests mild iliofemoral or femoral-popliteal disease on the right and moderate iliofemoral disease on the left; aortoiliac disease (left worse than right) is …

Like segmental pressure measurements, PVR waveforms obtained at various levels of the lower extremity can be used to infer the presence and location of arterial occlusive disease. The normal pulse contour has a rapid upslope, a sharp systolic peak, a dicrotic notch, and a downslope that bows toward the baseline (Fig. 20.13). Downstream from stenotic segments, the waveform …
