What is the primary purpose of a Doppler ultrasound in vascular studies?
✔✔ To assess blood flow and detect abnormalities like stenosis or occlusions.
What is the most common artery affected by atherosclerosis in the lower extremities?
✔✔ The femoral artery.
What does a "to-and-fro" pattern in Doppler waveform indicate?
✔✔ It suggests a stenosis with disturbed flow, often at or near a narrowing.
What is the significance of the ankle-brachial index (ABI) in vascular assessments?
✔✔ It is used to evaluate peripheral artery disease by comparing the blood pressure in the ankle
and arm.
What is the normal range for an ankle-brachial index (ABI)?
✔✔ 1.0 to 1.4.
1
,How is a duplex ultrasound used in vascular diagnostics?
✔✔ It combines traditional ultrasound and Doppler imaging to assess both the structure and
blood flow in vessels.
What does a high peak systolic velocity indicate in a carotid artery duplex exam?
✔✔ It may suggest a significant stenosis or narrowing of the artery.
What is the main difference between arterial and venous ultrasound examinations?
✔✔ Arterial ultrasounds focus on blood flow and blockages, while venous ultrasounds evaluate
vein reflux and deep vein thrombosis (DVT).
What condition is most commonly associated with an elevated systolic velocity in the carotid
artery?
✔✔ Carotid artery stenosis.
What is the role of the jugular vein in a vascular assessment?
✔✔ It is commonly evaluated for signs of central venous pressure changes or thrombosis.
2
,What is a significant finding in an arterial Doppler study that suggests atherosclerotic disease?
✔✔ A biphasic or triphasic waveform in the affected artery.
What is the primary risk factor for developing deep vein thrombosis (DVT)?
✔✔ Prolonged immobility, such as after surgery or during long periods of bed rest.
What does the term "turbulent flow" mean in vascular ultrasound?
✔✔ It refers to disorganized blood flow, typically seen after a stenosis or in areas of abnormal
vessel geometry.
What is a common method for diagnosing deep vein thrombosis (DVT)?
✔✔ A venous ultrasound to visualize clot formation in the deep veins.
How does a color Doppler study aid in the evaluation of blood vessels?
✔✔ It provides real-time visualization of blood flow direction and speed, helping to identify
blockages or abnormalities.
3
, What is a common sign of an aneurysm in a vascular ultrasound exam?
✔✔ An abnormal bulging or dilation of the vessel wall.
What is the significance of a "monophasic" waveform on Doppler in the peripheral arteries?
✔✔ It typically indicates a more severe obstruction or occlusion of the artery.
What condition might cause a sudden loss of pulse in a limb during vascular assessment?
✔✔ Acute arterial occlusion, often due to embolism or thrombosis.
What does a spectral Doppler waveform assess in vascular studies?
✔✔ It measures the velocity and character of blood flow within a vessel.
What is the primary goal of treating a patient with peripheral artery disease (PAD)?
✔✔ To improve blood flow, reduce symptoms, and prevent complications like ulceration or
amputation.
What does the presence of collateral circulation in a vascular exam indicate?
✔✔ It suggests that other vessels have adapted to compensate for blocked or narrowed arteries.
