Venous Duplex Scanning is used to diagnose vascular conditions in the legs. This procedure can effectively detect blood clots in the legs that may cause dangerous conditions such as deep vein thrombosis or pulmonary embolism. While many diseased leg veins are visible on the skin in the form of varicose or spider veins, some patients may experience significant venous reflux, or back flow, that can only be detected through ultrasound imaging.
A Venous Duplex Scanning shows a thorough, detailed image of the veins, along with the direction of blood flow, to help accurately diagnose vascular conditions. The ultrasound lab is certified by the American College of Radiology, and has extensive experience to date performing almost 5000 studies. Dr. Stevens is a Registered Phlebology Sonographer, and his staff is certified as well.
Venous Duplex Scanning Procedure
The Venous Duplex Scanning procedure is a straightforward, noninvasive one, is performed in our certified ultrasound laboratory. During the procedure, a clear gel is applied to the targeted area of the legs and a transducer is moved across the site. The transducer sends out high frequency sound waves which produce an image on a screen of the blood vessels in question, showing any blockage, clot, narrowing, occlusion or spasm of the blood vessel being viewed.
Conditions which may be diagnosed through the use of Venous Duplex Scanning include:
- Venous insufficiency
- Deep vein thrombosis
- Thrombophlebitis
- Peripheral artery disease
- Vascular tumors
The patient experiences no pain during a Venous Duplex Scanning so there is no anesthesia or recovery required. Another advantage of this diagnostic test is that the image on the computer screen appears immediately so it can be reviewed by Dr. Stevens and the patient at the time of the procedure.
There are no risks associated with the ultrasound procedure. There is no exposure to radiation. Depending on the results of the Venous Duplex Scanning, the doctor will be able to personalize an appropriate treatment.

How accurate is Venous Duplex Scanning at finding vein issues?
Duplex ultrasound imaging for venous insufficiency has been used for more than 15 years. This safe, painless, noninvasive technology expands the capacity of Dr Stevens to examine the veins, and to make accurate recommendations based on the anatomy and pathophysiology of each case. The use of venous duplex scanning can help prevent errors in treatment selection by accurately identifying the patterns of varicose veins beyond what is possible in a standard visual and manual examination of the affected leg. The lab has been certified by the American College of Radiology for several years, confirming a nationally recognized standard of quality
- Pain, cramping, numbness, itching, swelling
- Pain made worse by standing
- Pain improved by elevating the leg
- Discoloration or hardening of the skin on the leg
- Ulceration of the leg
The ultrasound procedure is an alternative to venography or angiography. In addition to assisting in the diagnosis of ongoing vascular conditions, Venous Duplex Scanning may also be utilized to diagnose the extent of vascular injuries and to evaluate vascular repair. The process may also be used to pinpoint a location for needle or catheter placement.
Is there any pain or risks involved with the venous duplex?
No. The use of ultrasound imaging has been common for many years. It is the technology used for example during pregnancy to observe the growing fetus or to look at the heart. Ultrasound is completely noninvasive. It works by sending sound waves through the body. These waves "bounce" off of internal organs, providing a real-time, moving image of the inner workings of the body. Venous duplex scans are done to see what cannot be seen with the naked eye. The sound waves bounce off of the veins and create an image of the vein and the blood circulating through it. Though ultrasound is a form of imaging, it does not utilize radiation.
Is there any recovery involved?
No. Venous duplex ultrasound is completely non-invasive and has no residual effect on the veins or superficial tissue. You can resume all normal activities upon leaving the office.
How can I prepare for a Venous Duplex Scan?
You need not do anything to prepare for your venous duplex scan. It is ideal to wear loose, comfortable clothing to your appointment, though you may be given a hospital gown to wear for your procedure.
Can I have a procedure performed after my Venous Duplex Scan?
The venous duplex scan is primarily used as a diagnostic tool, and is the gold standard. It helps Dr. Stevens accurately diagnose the type of venous insufficiency that is present, if any at all. From there, an appropriate treatment plan can be developed and discussed with the patient. Because there may be multiple treatment options to consider, the clinical procedure is often scheduled for a separate appointment in the future.
