Veins are composed of layers of thin tissue. The vein wall consists of three layers: Tunica Adventitia - the strong outer covering of arteries and veins. It is composed of connective tissue as well as collagen and elastic fibers.
How big is a vein?
Vein Size. A vein can range in size from 1 millimeter to 1-1.5 centimeters in diameter. The smallest veins in the body are called venules. They receive blood from the arteries via the arterioles and capillaries. The venules branch into larger veins which eventually carry the blood to the largest veins in the body, the vena cava.
What is a clot in the veins called?
A clot that occurs in deep veins is called deep vein thrombosis . Vein problems can also arise from a defect. Varicose veins are the result of damaged vein valves that allow blood to pool in the veins. The accumulation of blood causes inflammation and bulging in the veins located near the skin's surface.
Why do veins have problems?
Vein problems are typically the result of a blockage or defect. Blockages occur due to blood clots that develop in either superficial veins or deep veins, most often in the legs or arms. Blood clots develop when blood cells known as platelets or thrombocytes become activated due to a vein injury or disorder.
What is the layer of arteries?
In arteries, this layer is composed of an elastic membrane lining and smooth endothelium (a special type of epithelial tissue) that is covered by elastic tissues. Veins do not contain the elastic membrane lining that is found in arteries.

Other times they are performed include post-procedure to make sure that blood flow has been restored to the area. In other cases, they might be performed to check for conditions that can develop with age such as:
How to check blood flow in arteries?
In order to form a clear picture of the status of your arteries and veins, your doctor can employ a variety of vascular studies. These are noninvasive tests that check the blood flow in various parts of your bodies. They make use of high-frequency sound waves (ultrasounds) to measure the amount of blood flow in your bodies. The sound waves echo off the blood cells in your arteries, and are read by a transducer probe against the skin. The transducer processes the echoes and sends them to a computer, which then displays them on a screen as either still images or videos. Vascular studies may use advanced types of ultrasound technology, such as color doppler imaging. This adds color to the ultrasound images to show the direction of blood flow, which can pinpoint blockages.

What is the purpose of ultrasound of the veins?
Ultrasound - Venous (Extremities) Venous ultrasound uses sound waves to produce images of the veins in the body. It is commonly used to search for blood clots , especially in the veins of the leg – a condition often referred to as deep vein thrombosis. Ultrasound does not use ionizing radiation and has no known harmful effects.
What is Venous Ultrasound Imaging?
Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. It is safe and painless. It produces pictures of the inside of the body using sound waves. Ultrasound imaging is also called sonography. It uses a small probe called a transducer and gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back. A computer uses those sound waves to create an image. Ultrasound exams do not use radiation ( x-rays ). Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. The images can also show blood flowing through blood vessels.
What are some common uses of the procedure?
The most common reason for a venous ultrasound exam is to search for blood clots, especially in the veins of the leg. This condition is often referred to as deep vein thrombosis or DVT. These clots may break off and pass into the lungs, where they can cause a dangerous condition called pulmonary embolism. If the blood clot in the leg is found early enough, treatment can be started to prevent it from passing to the lung.
How does the procedure work?
Ultrasound imaging uses the same principles as the sonar that bats, ships, and fishermen use. When a sound wave strikes an object, it bounces back or echoes. By measuring these echo waves, it is possible to determine how far away the object is as well as its size, shape, and consistency. This includes whether the object is solid or filled with fluid.
How does ultrasound work?

Patients typically present with hypertension. Aorta/iliac duplex: These studies include measurements throughout the aorta to rule out an aortic aneurysm.
What is the underlying problem with superficial venous disease?
Venous Reflux and Ultrasound. The underlying problem with most superficial venous disease is reflux or venous insufficiency. Valves in the veins of the legs are responsible for ensuring one-way flow of blood back to the heart. When these valves fail, due to many risk factors, venous reflux occurs.
What happens when venous valves fail?
When these valves fail, due to many risk factors, venous reflux occurs. Refluxing valves allow blood to fall back down the leg. Varicose veins start to pool with blood eventually leading to leg swelling and other signs and symptoms .
How long does it take to get DVT results?

What is normal circulation?
Normal Circulation. The veins return blood to the heart. There are two sets of veins in the legs: The veins in the leg deflate easily; blood flows under low pressure and against gravity. Two things help the blood pump more efficiently: The calf “muscle pump.”. As you walk, calf muscle movement pushes blood upward.
Why are some people more likely to develop a DVT?

How are the recordings of a physical exam received?
The recordings are received by running a small, smooth probe over various parts of your legs or arms.
Can a clot occur in a vein?
Clotting can occur after injury or in old var icose veins. Superficial thrombophlebitis usually responds very well to local treatment. Venous thrombosis (sometimes called phlebitis) is a blood clot in a deep vein, resulting in partial or complete blockage of blood flow in that vein.
Is DVT a serious health issue?
Unlike superficial thrombophlebitis, a DVT is a serious health concern, because it’s possible that the clot could break off and travel to your lungs. It is then referred to as a pulmonary embolus. The risk of pulmonary embolus is decreased if you recognize the symptoms of a DVT quickly and get it treated right away.
