Vein Disorders

Your arteries carry blood from your heart to the rest of your body and your veins carry blood back to the heart. Valves in the veins stop the blood from flowing backward.

In venous insufficiency, blood doesn’t flow back properly to the heart, causing blood to pool in the veins in your legs.

Several factors can cause venous insufficiency, though it’s most commonly caused by blood clots (deep vein thrombosis) and varicose veins.

When forward flow through the veins is obstructed — such as in the case of a blood clot — blood builds up below the clot, which can lead to venous insufficiency.

In varicose veins, the valves are often missing or impaired, and blood leaks back through the damaged valves.

In some cases, weakness in the leg muscles that squeeze blood forward can also contribute to venous insufficiency.

Risk factors for developing venous insufficiency include female gender, advanced age, history of blood clots,  obesity, pregnancy, smoking, prolonged standing, and trauma. 

Symptoms include swelling of the legs or ankles (edema), pain, leg cramps, aching, throbbing, itching, thickening or darkening of skin on your legs, a feeling of heaviness in your legs, or leg ulcers. 

Treatment Options

Comprehensive venous care

We encourage initial attempts at conservative treatment through​ weight control, low salt-diet, medically graded compression stockings, regular exercises, and leg elevation.

​For persistent disease, we offer a variety of non-surgical treatment options focus on destroying or removing problem veins and address conditions like spider veins and varicose veins.

Endovenous ablation

15 minute, office based procedure

Endovenous Ablation uses heat to treat a varicose vein. Closing off a problem vein reduces pressure on smaller, side-branch varicose veins. Endovenous ablation involves only one needle puncture, not incisions.

Nonthermal vein closure

A Happier, Healthier You

A small amount of medical adhesive is injected to seal  the diseased vein, rerouting blood to nearby healthy veins, which provides symptom relief


Dedicated vascular interventionalist
Sclerotherapy involves injecting the problem vein with a chemical. This causes the blood vessel to close up and dissolve. Sclerotherapy is the main treatment option for spider veins. It’s also used for treatment of certain varicose veins. It is performed in a short office visit. It causes little or no pain.
