Do you also have questions about blood flow in your veins? Let's talk about Vascular Ultrasound!

Do you sometimes wish there was a way to know exactly how the blood is flowing through your body? If your doctor says you have a problem with your veins, especially in your arms, legs, or neck, or if you yourself are experiencing similar symptoms, it's reasonable to think about this. Today we're going to talk about a test that can help you in such a situation. This is called a vascular ultrasound.

What is this vascular ultrasound?

Simply put, a vascular ultrasound is a noninvasive test that does not cause any pain to the body . Some people also call it a 'Duplex Study'. This mainly looks at how blood is moving through the blood vessels in your arms, legs, and neck, that is, whether blood circulation is good.

Think about it, just like cars on a road, blood flows through our veins. Sometimes the road can get blocked, or the road can get narrow, right? In the same way, problems can arise inside our veins. This ultrasound test uses high-frequency sound waves to create detailed images of the soft tissues and blood vessels inside the veins. We cannot hear these sound waves, but the data they receive is converted into images using a computer.

In what situations does the doctor recommend doing this?

There are several reasons why your doctor may suggest a vascular ultrasound. The main one is to check the way blood flows through your veins and arteries – the blood vessels . This test can help confirm if you have any of the following conditions:

• Atherosclerosis: This is when fat and cholesterol build up inside the walls of the arteries, narrowing them. It's like rust building up inside a water pipe, clogging the passageway for the water.
• Blood clots: Blood clots can form inside the veins. These are very dangerous because they can become dislodged and lodge in the heart, lungs, or brain, causing serious problems.
• Carotid artery disease: This is a condition that occurs in the main arteries that carry blood to the brain from both sides of the neck. If these arteries become blocked, conditions such as stroke can occur.
• Chronic venous insufficiency: Simply put, it's when blood doesn't flow properly back to the heart through the veins in the legs. This can cause swelling and pain in the legs.
• Deep vein thrombosis (DVT): This is also a blood clot, but it occurs especially in the deep veins of the legs.
• Extracranial carotid artery aneurysm: A carotid artery outside the skull (in the neck) becomes weak and bulges like a balloon. This is also dangerous because it can burst.
• Peripheral artery disease: A disease caused by blockage or narrowing of the arteries that supply blood to the arms and legs.
• Vascular disease: Any disease that occurs in the blood vessel system in general.
• Varicose veins: You've probably heard of this. The veins in the legs appear blue, purple, and twisted, like they're knotted together.

Imagine, there is a person named Nimal. For some time now, he has been experiencing pain in one of his legs when he walks, along with some swelling. The doctor suspected that it might be a ``deep vein thrombosis (DVT)''. Then, this vascular ultrasound can be done to see if there is actually a blood clot.

What symptoms would make me need this type of test?

There are certain symptoms that your doctor may recommend if you have them. For example:

• If you feel like your legs are burning.
• If the muscles are weakened and thin, it is called ``Muscle atrophy``.
• If you have pain in your buttocks, hips, thighs, or groin, especially when walking.
• If you have non-healing ulcers on your legs.

Not only for these symptoms, doctors use this vascular ultrasound in other situations.

• After an organ transplant, check to see if the new organ is receiving adequate blood flow.
• See if someone is suitable for angioplasty (a treatment in which a blocked artery is widened with a balloon-like device).
• See how your veins are doing after bypass surgery.

Who is doing this test?

This vascular ultrasound test is performed by an ultrasound technologist . These people are specially trained to perform ultrasound tests. So you have nothing to worry about, they know this very well.

How does this vascular ultrasound work?

This is very simple. As I mentioned before, it uses high-frequency sound waves . These sound waves penetrate the surface of your skin and travel through soft tissue and blood vessels.

As they travel, the sound waves bounce back, like a ball hitting a wall. These returning sound waves (called echoes) are captured by a computer and used to create pictures or videos. The doctor can look at these pictures to see exactly what is happening inside the veins.

Actually, it's a bit like the way bats fly at night. Bats emit sound waves, and when they bounce off something, they know what's ahead. This is the same thing, but they're looking inside the body.

How should you prepare for this?

This is another good thing about this test. There is no need to prepare too much for it.

• Arrive at the appropriate location (hospital or clinic) about 15 minutes before your test time.
• Wear comfortable, loose clothing . Tight clothing may make the test difficult.
• It's better to leave jewelry and valuables at home.
• Sometimes you may be asked to wear a special hospital gown. Do as they tell you.

What happens during the test?

When you go into the examination room, you will be asked to lie down on an examination table .

Then, the ultrasound technician will apply a special gel (lubricating gel) to the areas of your skin that need to be examined (for example, on your legs if you have a leg, or on your neck if you have a neck). This gel may feel a little cold, but it helps the sound waves penetrate the skin better.

Then, he or she will place a special device called a transducer (it's like a small microphone) on the skin where the gel was applied and move it back and forth. You may feel a slight push while doing this, but it won't hurt.

The amazing thing is, sometimes you can even hear your own blood flowing through your veins! It might sound like a 'duk-duk' or a 'fush-fush' or a whirring sound. That's how sound waves capture the flow of blood.

What to expect after the test?

Once the test is over, the technician will wipe off the gel that was applied to your body. After that , you can go back to your normal activities without any problems. If you are a person who goes to work, you can go back to work, and if you are a person who works from home, there is no problem in doing that work.

Are there any risks or side effects to this?

This is the most important thing. Vascular ultrasound is a very safe test. It does not use any radiation like X-rays. Therefore, you will not experience any side effects from this test. Even pregnant mothers can do this safely. So, do not be afraid of this at all.

If you're wondering, "This won't cause any problems, right, Doctor?", the answer is, "No, it won't!"

What kind of information do doctors get from this?

This test gives the doctor a lot of valuable information about your vascular system.

• How fast (or slow) the blood moves through your body .
• This allows the doctor to understand if something is blocked inside a blood vessel (for example, a blood clot or a fatty layer (plaque)).
• Or you can check to see if the blood vessels are narrow .

Based on this information, the doctor will decide what further treatment you need.

How long does it take for the report to arrive?

The images from the test are evaluated by a radiologist . This is a doctor who specializes in diagnosing diseases by looking at things like X-rays and scans. He or she will look at the images carefully, analyze them, and create a report. After creating the report, it will be sent to the doctor who ordered the test for you.

It's hard to say exactly how long this will take. It usually takes a day or two, and sometimes it can take longer. It can vary depending on where the test is done and how busy the hospital is. You can ask the people there when you get the test to find out how long it usually takes.

What time should I call the doctor after the examination?

As I mentioned before, there are usually no side effects to be expected from this vascular ultrasound test. However, in the rare case that you develop a new symptom or if an existing symptom worsens , for example, if you experience pain, redness, or swelling at the site of the test, it is a good idea to inform your doctor. But remember, these things happen very rarely.

So, the final take-home message:

Okay, so now you have a good understanding of Vascular Ultrasound. Here are some things to keep in mind:

• This is a painless, non-invasive, and very safe test.
• This allows you to see how blood flows through the veins in your arms, legs, and neck .
• This helps to diagnose many medical conditions, such as blood clots, vein blockages, and narrowing of the veins .
• This doesn't require any special preparation, and once you're done, you can go about your normal business.
• Don't worry about any side effects.

So, if your doctor asks you to do this kind of test, do it without any unnecessary fear. Because this is a very valuable test that will help you know exactly what your health condition is and start the necessary treatment.
