Vascular ultrasound is a valuable diagnostic tool utilized by healthcare providers to assess blood flow within the arteries and veins of various parts of the body, including the arms, neck, and legs. It is a noninvasive imaging technique that relies on high-frequency sound waves (ultrasound) to create real-time images of blood vessels and the flow of blood through them.
​
Purpose:
Healthcare providers use vascular ultrasound for several purposes, including:
​
-
Diagnosing Blood Clots: Vascular ultrasound can detect the presence of blood clots (thrombosis) within the arteries and veins. This is crucial for diagnosing conditions such as deep vein thrombosis (DVT) in the legs or arms, which can lead to serious complications if left untreated.
-
Assessing Peripheral Artery Disease (PAD): By evaluating blood flow and detecting narrowing or blockages in the arteries, vascular ultrasound helps diagnose peripheral artery disease. PAD restricts blood flow to the extremities, leading to symptoms such as leg pain, cramping, and numbness.
-
Evaluating Candidates for Angioplasty: Vascular ultrasound helps determine if a patient is a suitable candidate for angioplasty, a procedure used to widen narrowed or blocked arteries. By assessing the severity and location of arterial blockages, healthcare providers can make informed decisions about treatment options.
-
Monitoring Blood Vessel Health: Patients who have undergone procedures such as bypass surgery may undergo vascular ultrasound to monitor the health and function of the repaired or bypassed blood vessels. It helps healthcare providers assess the effectiveness of the treatment and detect any complications, such as restenosis (re-narrowing of the blood vessel).
​
Procedure:
During a vascular ultrasound examination:
​
-
Ultrasound Gel Application: A clear gel is applied to the skin over the area being examined. This gel helps transmit sound waves and ensures good contact between the ultrasound probe and the skin.
-
Ultrasound Probe Movement: The healthcare provider or sonographer gently moves the ultrasound probe over the skin in the area of interest. The probe emits high-frequency sound waves, which bounce off blood cells and tissues and are then converted into real-time images displayed on a monitor.
-
Image Interpretation: The healthcare provider interprets the images to assess blood flow, identify any abnormalities or blockages, and make a diagnosis.

Vascular ultrasound is safe, painless, and noninvasive, making it an ideal tool for evaluating blood flow and diagnosing vascular conditions without the need for surgery or contrast agents. It provides valuable information that guides treatment decisions and improves patient outcomes.
