OBJECTIVE: The main objectives of this study were to evaluate the sensitivity and specificity of duplex Doppler ultrasonography in the study of hemodialysis peripheral vascular access dysfunction and to analyze the resistance index and flow in the afferent artery.
Follow up studies after angioplasty or atherectomy. Preparation Venous Doppler testing is used to check the veins in your legs for blood clots. The test is done

2013 Jun; 12(2):102-109 the CTA examinations. The equipment used in the present study were Elscint Twin Flash / Dual Slice Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to generate imaging of the movement of tissues and body fluids (usually blood), and their relative velocity to the probe.By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart valve, its speed and direction can be determined and Evaluation of signs and symptoms which may suggest decreased blood flow in the arteries and/or veins of the neck, legs, or arms. Evaluation of previous procedures that were performed to restore blood flow to an area. Evaluation of a vascular dialysis device, such as an A-V fistula in the arm.

Doppler waveforms refer to the morphology of pulsatile blood flow velocity tracings on spectral Doppler ultrasound. Waveforms differ by the vascular bed (peripheral, cerebrovascular, and visceral circulations) and the presence of disease.
Management of patients with peripheral artery disease (compilation of 2005 and 2011 ACCF/AHA Guideline Recommendations): a report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines. Vascular Surgery Abbreviations Below is a list of medical abbreviations commonly found in vascular surgery articles, textbooks, and other resources.
A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs.
Key words: Peripheral arterial occlusive disease; ultrasound,.

A Doppler ultrasound study is usually part of a vascular ultrasound examination.
During the study, the patient is asked to breath-hold or breathe quietly in order to obtain adequate spectral Doppler samples. The abdominal aorta is usually evaluated first via an anterior approach by placing the transducer just below the xiphoid process of the sternum. A Doppler ultrasound can help check whether an issue such as a blockage is impeding blood flow.

This exam shows any blockage in the veins by a blood clot or “thrombus” formation. Normal Circulation. The veins return blood to the heart. A Doppler ultrasound can detect differences in pitch as blood cells move through your blood vessels.
2020-07-15 · Spectral Doppler waveform assessment has been the principal diagnostic tool for the noninvasive diagnosis of peripheral artery and venous disease since the 1980s. 36,37 The absence of uniformly accepted, standardized descriptors for arterial and venous Doppler waveforms has been a long-standing point of controversy 38 and the main impetus for the development of this consensus statement, which is a major step towards clarifying and standardizing the key definitions and descriptors
