Whether you’re suffering from varicose veins or spider veins, the experts at the Precision Vein Center are here to help. Learn about the different vein treatments we provide for various vein conditions. Call us at 262.292.3151 to schedule your complimentary vein screening.

Schedule your complimentary varicose vein screening.


As a new patient concerned about their vein health, we recognize it’s important to have a thorough understanding of your diagnosis. We believe each patient should leave their first appointment with a full understanding of their vein diagnosis as well as the preferred treatment recommendations specific to their condition. The Precision Vein Center does not require multiple appointments to achieve a diagnosis.

Your first Precision Vein appointment includes a personal consultation with Dr. John Tomashek as well as a vascular ultrasound. Following the ultrasound, Dr. Tomashek will discuss your ultrasound results and family history, as well as provide his recommendations and treatment plan. Each patient is unique; some may need an outpatient varicose vein procedure while others may only need sclerotherapy for spider veins. Rest assured, after receiving Dr. Tomashek’s thorough evaluation you will have the education and treatment recommendations necessary to plan your return to active living!

If a varicose vein procedure is recommended, you can expect your post-procedure followup appointment to include another vascular ultrasound, the removal of any stitches as well as an opportunity to discuss any of your post procedure questions.

There are many myths and misunderstandings related to varicose vein disease. Years ago, the only treatment for varicose veins was an invasive surgical procedure, performed in the hospital, called vein stripping. It was a painful process and required at least two overnights in the hospital with a high risk of infection. Today, varicose vein treatment has advanced profoundly with many minimally invasive procedures, performed in the office, to correct venous insufficiency and varicose veins. Patients no longer need to suffer from the pain, swelling, and discomfort of varicose veins.

PRECISION VEIN offers multiple treatment modalities for varicose veins, not simply one. Each treatment is tailored to a patient’s individual pattern of venous reflux (determined with the vascular ultrasound examination) as well as family health history. We offer three different treatment options for varicose veins including radiofrequency ablation (RFA), endovenous laser therapy (EVLT), and the VenaSeal™ procedure. These minimally invasive procedures are excellent treatment options and are more than 97% effective in treating the source of varicose veins, with most patients noticing an improvement in how their leg feels within 24 hours. The procedures are performed in the office and patients typically return to their usual level of activity the same day. Medically prescribed support hose and/or bandages may need to be worn for several days to several weeks to assist in the resolution of the veins.

Radiofrequency Ablation (RFA)

What is Radiofrequency Ablation (RFA)? RFA is often referred to as one of the greatest advancements in the treatment of varicose veins. Radiofrequency ablation (RFA) is an innovative, minimally invasive procedure. The goal of the procedure is to restore healthy circulation throughout the leg. During RFA, heat is delivered to the affected vein wall, forcing it to close, and interrupting the backward flow of blood through the vein. This procedure corrects the underlying cause of varicose veins. Following the RFA procedure, blood flow is redirected to healthy veins, restoring healthy circulation in the leg. This technique has replaced the much more invasive surgical vein-stripping procedures.

Endovenous Laser Therapy (EVLT)

Much like Radiofrequency Ablation (RFA), Endovenous Laser Ablation (EVLT) uses heat to treat the underlying cause of varicose veins. EVLT is a minimally invasive procedure that restores healthy circulation throughout the legs. Laser vein ablation is one of the safe and effective treatments for saphenous vein reflux, the underlying cause of most varicose veins.

Microphlebectomy or Phlebectomy

To achieve healthy circulation and improved appearance, sometimes a multi-step treatment plan is best. Varicose veins may require additional treatment if they remain bulging and visible through the skin after healthy circulation has been restored using either radiofrequency ablation, endovenous laser ablation, or the VenaSeal™ procedure. Microphlebectomy is the procedure that is performed to remove the remaining bulging surface veins, resulting in painfree, healthy legs


Sclerotherapy is a cosmetic medical procedure for treating spider veins. A tiny needle is used to inject a solution directly into the vein. The solution irritates the lining of the vein, causing it to swell and close. Over time, the body will absorb the treated vein. Mild discomfort may occur when larger veins are injected. The number of veins injected in one session is variable, depending on the size and location of the veins as well as the patient’s overall medical condition.

Our eVein Screening helps to personalize your care experience.


Stage 1: Spider Veins

Spider veins affect 50% of Americans and one of the most common reasons people tend to cover their legs. Many times, avoiding shorts or bathing suits. Although they are commonly perceived as only a cosmetic issue, they can often be a symptom of the more serious problem of venous insufficiency, especially if you have symptoms such as heaviness, aching and/or fatigue in the legs.

Stage 2: Varicose Veins

Varicose veins are visible veins in the leg that bulge, often protrude through the skin, and affect approximately 40% of the U.S. population. These veins form because of venous insufficiency due to a faulty valve creating protrusion. Patients dealing with varicose veins often limit social activities due to the pain and embarrassment associated with varicose veins. Left untreated, symptoms may worsen.

Stage 3: Leg Swelling

One of the most common complaints we often hear is “My legs feel swollen, tired, and heavy—especially at the end of the day”. The leg veins are responsible for draining blood out of the legs and returning it to the heart. When the valves inside the veins don’t work properly, blood tends to build up and pool in the leg, which over the course of the day leads to increased swelling. Swelling in the feet and legs often leads to the legs feeling tight and heavy. This can limit mobility, and the ability to take part in daily activities and often can affect sleep schedules.

Stage 4: Skin Darkening + Thickening

The leg veins are often described as the drainage system for your skin. Similar to when a sink drain becomes clogged, with vein reflux a backward flow prevents adequate blood circulation in the legs. As the blood pools over time, it can leak out of the damaged veins, into the skin. This results in dark, thickened patches of skin that often are very itchy.

Stage 5: Skin Ulcers or Venous Ulcers

One of the most dreaded complications of vein disease is developing an open wound on the leg called a venous ulcer. Venous ulcers usually occur on the inner aspect of the leg just above the ankle. They often develop in discolored and abnormal patches of skin and are due to lack of oxygen and nutrients. These ulcers may take years to heal and unless the underlying circulation problem is repaired, the wounds will likely return.
