Venous Disease Scan
Veins are blood vessels that carry blood back to the heart, working against the force of gravity. Your calf muscles and a system of valves in the veins help to move blood towards the heart. A variety of tests can assist in the diagnosis of venous disease:
- Venous duplex study is an ultrasound (imaging) test of the major leg or arm veins to determine whether blockage (clot) is present. The valves in the veins can also be tested and may be indicated when varicose veins are present.
- Vein mapping uses ultrasound and is a process of locating and measuring veins in the arms or legs to be used for bypass surgery or dialysis access.
What to expect during the test
- You may be asked to change into a gown and remove all jewelry.
- A venous disease scan requires no previous preparation. The test is completely safe and painless, and only takes between 30 and 45 minutes to complete.
- You will lie on your back while a technologist places a sensor on several areas of your body. The sensor will have a small amount of cool gel on the end. The gel helps produce clearer pictures, and will not harm your skin.
- The only discomfort you may feel is the coolness from the gel or a slight pressure from the sensor as it moves along your body.
- You may hear swooshing sounds during the test as the sound waves are detected.
What to expect after the test
- If your scan results are normal you may resume your regular activities immediately following the scan.
- A vascular surgeon will use your scan to assess any blockages or abnormalities in your veins.
- If your results are abnormal your physician will be contacted immediately, and you may be admitted to the hospital for further tests or treatment.
- Results from your scan will be prepared by the vascular surgeon, and a report will be mailed to your primary care physician.
If you have any questions about your care after you return home, call your physician's office.
