PAD means you have narrowed or blocked arteries -- the vessels that carry oxygen-rich blood as it moves away from your heart to other parts of your . Restricted blood flow (atherosclerosis) in other parts of the body. One of the most critical decisions relates to whether a patient requires therapeutic intervention and should undergo additional imaging studies. Low-frequency (2 or 3MHz) transducers are best for evaluating the aorta and iliac arteries, whereas a higher frequency (5 or 7.5MHz) transducer is adequate in most patients for the infrainguinal vessels. For additional information visit Linking to and Using Content from MedlinePlus. The index is a ratio of the two measurements. 15.1 ), pulsed Doppler spectral waveforms may be obtained at more widely spaced intervals when color flow Doppler is used. Spectral waveforms obtained distal to a severe stenosis or occlusion are generally monophasic and damped with reduced PSV and a delayed systolic rise, resulting in a tardus-parvus flow pattern ( Fig. You will not feel any pain; however you will feel mild pressure from the blood pressure cuff and the transducer.

Several large branches can often be seen originating from the distal superficial femoral artery and popliteal artery. It can also tell the width of a blood vessel and reveal any blockages. In other words, having varicose veins doesnt mean you have CVI. For lower extremity duplex scanning, pulsed Doppler spectral waveforms should be obtained at closely spaced intervals because the flow disturbances produced by arterial lesions are propagated along the vessel for a relatively short distance (about 1 or 2 vessel diameters). The reverse flow component is also absent distal to severe occlusive lesions. Spectral waveforms obtained from a normal proximal superficial femoral artery (, Lower extremity artery Doppler spectral waveforms. Closely follow your providers instructions. But CVI damages those valves, causing blood to pool in your legs. The stages are based on clinical signs, which are things your provider can see or feel when they examine your legs. The ability to visualize blood flow abnormalities throughout a vessel improves the precision of pulsed Doppler sample volume placement for obtaining spectral waveforms. LE. However, it should be emphasized that color flow Doppler and power Doppler imaging are not substitutes for spectral waveform analysis, which is the primary method for classifying the severity of arterial stenosis. With the cuffs inflated, the healthcare provider uses a handheld device called a transducer to apply ultrasound waves to different parts of your leg. But compression therapy is very important to help your veins work better and ease your symptoms. LE Medical Abbreviation / Page 2.

These are readily visualized with color flow or power Doppler imaging and represent the geniculate and sural arteries (see Chapter 11 ). Overall, chronic venous insufficiency affects about 1 in 20 adults. Because flow velocities distal to an occluded segment may be low, it is important to adjust the Doppler imaging parameters of the instrument to detect low flow rates. This is necessary because the flow disturbances produced by arterial lesions are propagated along the vessel for a relatively short distance. Therefore the flow is laminar, and the corresponding spectral waveform contains a narrow band of frequencies with a clear area under the systolic peak ( Figs. A care provider measures your blood pressure in both arms and both ankles. As discussed in Chapter 12 , the nonimaging or indirect physiologic tests for lower extremity arterial disease, such as measurement of ankle-brachial index, segmental limb pressures and pulse volume recordings, provide valuable physiologic information, but they give relatively little anatomic detail.
