What is a Venous Reflux Exam?

Updated on: August 18, 2014

Venous reflux exams have been used to confirm or exclude a diagnosis of venous valvular insufficiency for individuals in Boynton Beach, Florida and throughout the country. These exams are also used to evaluate vein function and to check for venous reflux. Those who have been diagnosed with venous reflux or venous valvular insufficiency may be good candidates for this exam, while those experiencing any related symptoms like varicose veins, venous ulcers, chronic swelling, pain and heaviness in the legs, or skin discoloration may also be considered good candidates for venous reflux exams.

There are two types of exams. One involves the use of a sensor that is attached to the leg to measure how long it takes blood to be pumped to the heart and back to the ankle. The other uses ultrasound to map the veins and determine the direction and velocity of blood flow, and to identify any problem veins and the level of valve function.

The first type of exam involves first attaching of a sensor to the patient's leg and then having the patient pump his or her foot up and down to promote blood flow. The sensor will measure the length of time that it takes the blood to go to the heart and then return to the ankle. The results from the exam may be available within a few days of the exam. The results include the measurements necessary to allow the Boynton Beach vein specialist to determine the function of the valves, and to confirm or exclude the diagnosis of venous reflux or venous valvular insufficiency.

The second type of exam involves the use of ultrasound technology to map the veins. A handheld ultrasound wand is used on both legs as the patient lies on the exam table. A conductive gel may be used and the wand is passed over the exam area. The reflection of sound waves allows an image to be created so the Boynton Beach vein specialist may view the valves and the veins to determine the movement of blood. About 40 minutes to an hour are necessary to complete the exam for both legs.

This is a completely non-invasive treatment so no recovery time or downtime is necessary after treatment. What's more, there are no risks involved with this procedure, making it a convenient and straightforward test to check for venous valvular insufficiency or venous reflux.
