Th duplex/doppler ultrasound test combines doppler and ultrasound technology to examine the blood flow in the major arteries and veins in the arms and legs with the use of ultrasound (high-frequency sound waves). The image allows us to watch the blood flow through your veins and arteries, and make it possible for us to see plaque, lesions, narrowing, clots and obstructions. The sound waves move through your leg tissue and a computer translates the sound waves into an image on a video screen. The doppler device sends sound waves into your leg. Color doppler testing is used to assess blood flow. These tests are critical to an accurate diagnosis and, ultimately, the best plan of treatment. Here we perform noninvasive evaluations and diagnoses of the veins and arteries in your arms, legs, head and stomach. doi:10.14366/usg.At the Division of Vascular Surgery, we have an advanced, accredited noninvasive vascular laboratory. Doppler Ultrasonography of the Lower Extremity Arteries: Anatomy and Scanning Guidelines. Value of the duplex waveform at the common femoral artery for diagnosing obstructive aortoiliac disease. Spronk S, den Hoed PT, de Jonge LC, van Dijk LC, Pattynama PM. (2017) Radiographics : a review publication of the Radiological Society of North America, Inc. Noninvasive Physiologic Vascular Studies: A Guide to Diagnosing Peripheral Arterial Disease. Sibley RC, Reis SP, MacFarlane JJ, Reddick MA, Kalva SP, Sutphin PD. Pulsatile venous Doppler flow in lower limbs: highly indicative of elevated right atrium pressure. Characterizing Triphasic, Biphasic, and Monophasic Doppler Waveforms: Should a Simple Task Be So Difficult? Journal of Diagnostic Medical Sonography. Additional ultrasounds may be done over several days to check for new blood clots or to see if an existing one is growing. Journal of clinical and diagnostic research : JCDR. For the test, a care provider gently moves a small hand-held device (transducer) on the skin over the body area being studied. Accuracy of Common Femoral Artery Doppler Waveform Analysis in Predicting Haemodynamically Significant Aortoiliac Lesions. Rangankar VP, Taori KB, Mundhada RG, Rewatkar AD. Non-invasive methods of arterial and venous assessment. Journal of Diagnostic Medical Sonography. Confusion of peripheral arterial Doppler waveform terminology. Normal Doppler spectral waveforms of major pediatric vessels: specific patterns. Pulsatile venous flow is considered abnormal and is suggestive of elevated pressures in the right atrium 6. These categorizations differ for the cerebrovascular and visceral circulations, which normally have lower resistance. Diastolic flow reversal is generally considered normal but pandiastolic forward flow is abnormal in the peripheral arteries 2. Due to the controversy surrounding the definition of biphasic, there is disagreement about whether biphasic flow is normal 2. Triphasic arterial flow is considered normal in peripheral arteries and monophasic flow is considered abnormal 7.
