Venous Reflux Ultrasound

A venous reflux ultrasound evaluates whether the valves inside the leg veins are working properly. Healthy valves help move blood upward toward the heart. When valves leak, blood can flow backward and pool in the leg. This is called venous reflux or venous insufficiency.

Reflux can contribute to varicose veins, leg heaviness, swelling, aching, throbbing, skin discoloration, dermatitis, and venous ulcers. Because reflux is not always visible from the outside, ultrasound is one of the most important tests in modern vein care.

• Confirming venous reflux
• Finding which veins are leaking
• Measuring reflux severity
• Planning EVLT, RFA, VenaSeal, Varithena, ClariVein, phlebectomy, or ultrasound-guided foam treatment
• Supporting insurance documentation when symptoms are medical

A duplex ultrasound checks the anatomy of the veins and the direction of blood flow. The technologist evaluates specific superficial and deep veins and may use gentle maneuvers to see whether blood flows backward.

The test is non-invasive and does not require recovery time. You may be asked to stand or shift positions during the exam. The care team reviews the results and explains whether a medical treatment plan may be appropriate.

There is no downtime. If reflux is found, your plan may include compression, conservative care, vein closure, injection treatment, or staged procedures.

This test is commonly covered when symptoms and exam findings support medical necessity. Coverage depends on your plan and documentation.
