Venous reflux exams help evaluate efficiency of vein function and help check for venous reflux for patients in Phoenix, Arizona and around the country. They may also be used to confirm or exclude a diagnosis of venous valvular insufficiency. Venous reflux exams that utilize ultrasound or sensors are often more desirable and less invasive than other similar exams such as venography, arteriography and other possible diagnosis tools. It is important to discuss one's options with a trained professional before proceeding with any diagnostic tool or exam, of course.
There are two common types of non-invasive venous reflux exams. The first is rather simple and uses a sensor that is attached to the individual's leg to measure the time required for blood to be pumped up towards the heart and return to the ankle. The second type of non-invasive venous reflux exam involves ultrasound. This technology is used to map the veins and determine the direction and velocity of blood flow. This helps identify problematic veins and helps determined the level of functionality of the valves in the veins.
To perform the first type of venous reflux exam, the individual administering the test will attach a sensor to the patient's leg, and the patient is then instructed to pump his or her foot up and down. The sensor measures how long it takes for the blood to be pumped to the heart and return to the ankle. Results may be available a few days after the exam and help the doctor determine the functionality of the valves, and may help confirm or exclude a diagnosis of venous reflux or venous valvular insufficiency.
To perform the second type of venous reflux exam, a handheld ultrasound wand is used on both legs. A complete duplex ultrasound exam may be conducted during the screening. The patient will lie down on a table as the professional administering the test applies a conductive gel and passes the wand over the area that is being examined. The reflection of sound waves creates images allowing the physician to view the veins and valves to help determine the movement of the blood. About 40 minutes to an hour is typically required to perform the test on both legs.
There is no recovery required following these procedures and patients can return to normal activities or work immediately after the exam. Within a few days after the exam, the doctor should receive the results and consult you to formulate a treatment plan depending on what the results indicate. Further making non-invasive venous reflux exams an attractive option, there are no risks or complications associated with these exams.
