"The Northwest's First
Vein Center"


Willamette Vein Centré, for over two decades, has been the leader in state-of-art technology and cutting edge procedure for the treatment of all aspects of vein disease. The first -- and --only medical office in the Northwest to provide graduate training in Phlebology. Physicians from across the nation and around the world have come to Salem to rain under Dr. Wilson.

Ultrasound Guided Sclerotherapy

High tech ultrasound machines are used in many areas of clinical medicine to provide a visual window to structures beneath the surface of the skin. These same machines, used to visualize diseased refluxing veins deep under the surface of the skin, can now enable doctors trained in ultrasound guided sclerotherapy to safely and effectively treat the actual leaking vein causing varicose veins and spiders seen on the surface of the skin.

Ultrasound guided sclerotherapy gets to the source of the disease - the refluxingor leaking vein - and in doing so treats all types of diseased veins and spiders better, quicker, and more effectively than they've ever been treated before.

This technology is relatively new -- it was only developed about 15 years ago in France. It was first used in the United States by physicians in Chicago, who subsequently trained Willamette Vein Centre' personnel in its use. Willamette Vein Centre' was the first vein clinic in the Northwest to use this technique, and has trained scores of physicians around the country in its use.

What are the benefits of ultrasound guided sclerotherapy as compared to conventional sclerotherapy?

Better results. Quicker Results. Less Expense.

Because only ultrasound guided sclerotherapy gets to the source of diseased
veins deep under the surface of the skin, results from sclerotherapy treatment
performed via ultrasound guidance tends to be much better. Large varicose veins
can go away quickly and completely without surgery. Spider veins and so-called
feeder veins (reticular veins) often fade with fewer treatments and cosmetically
better results than when treated with conventional sclerotherapy or laser alone. Ultrasound machine
Since because ultrasound guided sclerotherapy gets to the source of the disease
(reflux), the results of treatment tend to be more permanent and less expensive
because fewer treatment sessions are necessary to get the job done.

When looking for sclerotherapy treatment, we suggest everyone inquire whether ultrasound guided sclerotherapy would be the right choice of treatment for them, whether they have large varicose veins or even small spiders.

Is ultrasound guided sclerotherapy only for large varicose veins?

No. Remember that all diseased veins on the surface of the skin - even spider veins - are caused, to some degree, by reflux. Only ultrasound guided sclerotherapy can "see" beneath the skin to allow treatment of feeder veins causing spiders. Therefore, nearly all new patients of Willamette Vein Centré - even those with only spider veins - undergo at least one ultrasound guided sclerotherapy treatment to be sure all sources of reflux are treated at the beginning treatment process.

Find out if sclerotherapy is right for you

Perhaps you know that sclerotherapy is just what you've been waiting for, and you're ready to schedule an appointment to get started. That's great. Just give us a call at (503) 399-0644 or (866) VEINS01 and schedule your appointment for a venous examination. If you're not exactly sure, or you'd like to know more, we can help you with that too. Simply call us and ask to have Brief Sclerotherapy Assessment. This brief examination will be done by Dr. Wilson for a fee of only a $75 charge to the patient; afterwards, Dr. Wilson will discuss your treatment plan with you.

VNUS Closure

Leg drawing There are several different techniques that can be used for venous ablation treatment. The first technique is a variation of a procedure that was first used in the 1930's for the treatment of hemorrhoids, and is known as "radiofrequency closure" or "VNUS closure". With this technique a set of wires is inserted into the offending vein, and an electrical current is used to slowly "cook" the vein. The term "radiofrequency" is used because the frequency of the current that is used is just below the frequency of an AM radio station. Typically, the treatment takes a few minutes per vein, and the set of wires are slowly withdrawn during this time to ensure treatment of the entire course of the vein.

Endovenous Laser Treatment (pictured)

The second technique make use of a more recent technical development — that of the laser. This procedure, which is known as "Endovenous Laser Treatment" (EVLT) or "Endovenous Laser Ablation Treatment" (EVLAT), involves passing a laser optic fiber into the vein and "cooking" the vein with laser energy. This technique also damages the vein,with the actual treatment taking about a minute.

Steam Technique

The third technique is still considered investigational and
involves a very old technology -- steam. With this approach a catheter is placed in the vein and the vein is "cooked" by injecting hot steam into the catheter or by injecting water that is then converted to steam by a small heating element in the tip of the catheter. It appears that this technique, while being just as safe and effective as both Endovenous Laser and VNUS Closure ablation, offers no particular advantage over these two procedures.


Willamette Vein Centré was one of ten research sites selected by the FDA for the clinical investigation of endovenous laser treatment in 2001. Since then over 900 offices, clinics and hospitals have joined us in using endovenous laser treatment for venous reflux disease. More recently, we have added VNUS Closure to our vein treatment repertoire, thus giving our patients the option of choosing from one of two excellent ablation techniques.
