What is and how is a venous reflux study performed?
A venous reflux study is a noninvasive ultrasound examination. This test is performed in a vascular lab by a sonographer (also called a vascular ultrasound technologist). The test usually takes between 1 and 2 hours, depending on whether one or both legs are examined.
How do they do a venous reflux ultrasound?
During the Ultrasound You may be asked to change positions in order to obtain images of each vein. The technician will press the transducer on your legs and will squeeze your legs. This may cause a slight discomfort for some patients. A venous insufficiency ultrasound usually takes 60-75 minutes to complete.
How long does a venous insufficiency test take?

What is a venous reflux scan?
To identify the unhealthy valves, an ultrasound machine is used to examine the legs. The ultrasound machine can visualize blood flow using sound waves that travel through the legs and send back signals to the machine. This is a very safe study and does not involve radiation or injecting medicine into the body.
What is the treatment for venous reflux?
The easiest way to treat venous reflux is by wearing compression stockings. These can help improve circulation by applying pressure to the legs. A person with severe VRD may also need surgery. Speak with a doctor if any warning signs or symptoms of venous reflux occur, such as pain, muscle cramps, or swelling.
What is the best treatment for venous insufficiency?
Keeping your legs raised (elevated) can reduce swelling and help increase blood flow. Wearing compression stockings may also help. Regular exercise can also improve blood flow.
What is the most common cause of venous insufficiency?
Deep vein thrombosis (DVT) is the most common cause of chronic venous insufficiency. The blood clot damages the valve in your leg vein. People with a history of DVT face a higher risk of developing CVI.
What worsens venous insufficiency?
Avoid Tight Clothing and High Heels. Tight clothing or shoes can restrict blood flow in the legs and increase the risk of chronic venous insufficiency. High-heeled shoes can also impede blood flow in the legs. For this reason, your NYU Langone doctor may recommend wearing shoes with a low heel.

The duration of reflux is known as the reflux time. A reflux time of >0.5 seconds for superficial veins and 1.0 second for deep veins is typically used to diagnose the presence of reflux. A longer duration of reflux implies more severe disease but does not correlate well with clinical manifestations.
Can venous reflux be reversed?
First, I want to be clear that there is no way to actually reverse the cause of venous insufficiency, only the symptoms. Damaged valves inside the vein cannot be repaired, but there are plenty of ways to minimize the impact of the reflux they cause. Many of my patients do eventually become symptom-free.
What is considered severe venous reflux?
A reflux time of >0.5 seconds for superficial veins and 1.0 second for deep veins is typically used to diagnose the presence of reflux. A longer duration of reflux implies more severe disease but does not correlate well with clinical manifestations.

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 .

What is a vein reflux test?
Venous reflux testing with ultrasound is a test utilizing high frequency sound waves to obtain images of veins in the arms or legs and evaluate for reflux. This test is used to determine if there are any problems with the vessels which may result in varicose veins, pain and swelling. The technologist applies an acoustic gel on your arms or legs over the area to be viewed. A painless instrument called a transducer is gently moved across that portion of your body to visualize the inside of the veins.

in my studies i noticed in some patients a small reflux in great saphenous vein and in cfv in supine position after valsalva test but when the patient stand up i don't see the reflux.anyone noticed the same?anyone know the explanation ?
How to do a Doppler ultrasound?
First, the technologist will explain the exam and may ask you historical questions that aid in obtaining a more diagnostic study. You may be asked to undress below the waist and a drape or towel may be placed over you. You will lie on a specialized table that will tilt at an angle. Gel will be spread on your leg (s) to improve the quality of the sound waves. A small handheld unit called a transducer is pressed against your skin and moved back and forth over it. A picture of the blood vessels can be seen on a video monitor. The sonographer will apply compressions at different levels down each of your legs. You will need to lie very still while the ultrasound scan is being done and you may be asked to manipulate or bend your leg at different stages of the test. Doppler sonography is performed throughout the exam and you may hear noises from the machine during this time.

What happens when veins are damaged?
If these valves become damaged and do not fully close, they can allow blood to flow with gravity, causing reflux and impairing blood circulation.
How to diagnose CVI?
A doctor can diagnose CVI by examining the leg or surrounding body parts. They may use a handheld tool called a Doppler ultrasound to listen to the blood flow in the leg. To confirm their findings or improve the accuracy of their examination, a healthcare professional may also order a venous duplex ultrasound exam.
What causes a vein to enlarge?
Causes. Any condition that blocks the major leg veins or damages or weakens their valves can cause VRD. Conditions that can lead to VRD include: deep vein thrombosis (DVT) vein wall weakness , which causes veins to enlarge to the point where the valves cannot close. a congenital (from birth) absence of vein valves.
What type of surgery is used to remove a vein with reflux?
Types of surgeries used to treat CVI include: Vein stripping: A procedure to remove the vein with reflux, often performed while someone is under general anesthesia. Ultrasound-guided foam sclerotherapy: With this treatment, a doctor introduces a tiny tube into the vein using ultrasound imaging as guidance.

What are the procedures for venous insufficiency?
Venous insufficiency procedures fall under one of three categories: 1 Thermal Tumescent (TT) modalities include radiofrequency or laser ablation. These treatments use heat and a tumescent (a chemical compound that produces anesthesia). 2 Nonthermal Nontumescent (NTNT) modalities include ultrasound-guided foam sclerotherapy, mechanochemical ablation (also known as MOCA and commercially known as Clarivein ). Most recently cyanoacrylate glue (known commercially as VenaSeal) hit the market. These modalities do not rely on heat and do not require a tumescent. 3 Nonthermal Tumescent (NTT) includes vein stripping with tumescent.
Why do veins have one way valves?
In healthy veins, valves are one way, meaning they allow the blood to move upward and then close so blood continues to move in the right direction. When veins are unhealthy, the valves become weak, and instead of closing, their laxity allows for two way blood flow. This causes venous insufficiency or CVI. See the illustration below.
What is the best treatment for venous reflux?
