Venous Reflux Exam

Venous Reflux Exam

Are there significant advantages of a venous reflux exam when compared to other similar procedures?

The ultrasound techniques used are non-invasive. This is not the case with other diagnostic tools such as venography and arteriography.

What Actually Is Venous Reflux Exam?

Venous reflux exam, also known as a venous reflux study or venous insufficiency study, is a diagnostic test used to evaluate the blood flow in the veins of the lower extremities. This test is typically used to diagnose chronic venous insufficiency (CVI), a condition in which the valves in the veins of the legs become weakened or damaged, causing blood to pool and flow in the wrong direction.

The venous reflux exam is a non-invasive procedure that involves the use of duplex ultrasound technology to assess the blood flow in the veins of the legs. During the exam, a technologist or radiologist will apply gel to the skin of the legs and use a handheld transducer to create images of the veins. The transducer emits high-frequency sound waves that bounce off the veins and create images on a computer screen. The exam typically takes between 30 minutes to an hour to complete.

The venous reflux exam can help diagnose CVI by identifying the presence of reflux, which is the backward flow of blood in the veins. If reflux is detected, the technologist or radiologist will measure the amount of blood flowing in the affected veins and the pressure in the veins. This information can help determine the severity of the condition and guide treatment options.

Treatment for CVI may include compression stockings, lifestyle modifications, and in some cases, minimally invasive procedures such as endovenous laser therapy or radiofrequency ablation.

In conclusion, the venous reflux exam is a non-invasive diagnostic test that can help diagnose chronic venous insufficiency by assessing the blood flow in the veins of the legs. If you are experiencing symptoms such as leg pain, swelling, or skin changes, or have a family history of venous insufficiency, you may benefit from this test. Consult with a medical professional to determine if a venous reflux exam is appropriate for you.

How long do the results take?

At the AVC the tests are done, you may receive the results right away. Other clinics may take a few days. Many dedicated vein specialist have the equipment for a venous reflux exam right in their own office. If you have to go offsite for the tests, your healthcare provider will likely receive your results within a few days.

Will my insurance cover the cost of a venous reflux exam?

Since venous reflux exams are typically ordered by your physician to confirm a clinical suspicion or diagnose a medical condition, medical insurance companies usually cover this exam. You may still be responsible for copays or deductibles.


Are there any risks associated with venous reflux exams?

There are no known complications or risks connected with venous reflux exams. It is a simple, non-invasive procedure that takes 30 minutes to an hour. Some people have reported feeling dizzy or lightheaded during the standing portion of the exam. This can be easily remedied by sitting down.

How does venous reflux differ from arterial insufficiency?

Venous reflux and arterial insufficiency are two different conditions involving the blood vessels, but they have distinct causes and symptoms:

1. Venous reflux: Venous reflux, also known as venous insufficiency, occurs when the valves in the veins of the legs do not function properly, leading to the backward flow of blood. This can cause blood to pool in the veins, leading to symptoms such as varicose veins, swelling, heaviness, and aching in the legs. Venous reflux is more common in the lower extremities and is often exacerbated by prolonged standing or sitting.

2. Arterial insufficiency: Arterial insufficiency, on the other hand, occurs when there is a narrowing or blockage in the arteries that restricts blood flow to the tissues. This can result in symptoms such as leg pain, cramping, weakness, and skin changes. Arterial insufficiency is more common in the arteries of the legs and feet and is often associated with conditions such as peripheral artery disease (PAD) or atherosclerosis.

What are the limitations of a venous reflux exam?

The limitations of a venous reflux exam include:

1. Limited view: The exam may only provide a limited view of the veins being examined, particularly if the veins are deep or located in areas that are difficult to access.

2. Interpretation: The results of the exam may be subjective and depend on the skill and experience of the examiner. Different examiners may interpret the results differently.

3. False positives: The exam may produce false-positive results, indicating venous reflux when it is not actually present. This can lead to unnecessary worry or treatment.

4. False negatives: Similarly, the exam may produce false-negative results, failing to detect venous reflux when it is actually present. This can result in a missed diagnosis and delay in appropriate treatment.
