What are varicose veins?

While arteries bring blood from the heart to the extremities, veins, by virtue of one-way valves, channel blood back to the heart. If these valves don't function well, the blood doesn't flow efficiently. The veins then become enlarged because they are congested with blood. These enlarged veins are commonly called spider veins or varicose veins. Spider veins are small red, blue or purple veins on the surface of the skin. Varicose veins are larger distended veins that are located somewhat deeper than spider veins. Pain in the legs is frequently related to these abnormal leg veins. Symptoms, often made worse by prolonged standing, include feelings of fatigue, heaviness, aching, burning, throbbing, itching, cramping, and restlessness of the legs. Leg swelling can occur. Severe varicose veins can compromise the nutrition of the skin and lead to eczema, inflammation or even ulceration of the lower leg. Vein disorders are not always visible, therefore diagnostic techniques are important tools in determining the cause and severity of the problem. In addition to a physical examination, non-invasive ultrasound and plethysmography tests are often used.

What cause varicose veins?

Heredity is the number one contributing factor causing varicose and spider veins. Women are more likely to suffer from these abnormal leg veins. Up to 50% of American women may be affected. Hormonal factors including puberty, pregnancy, menopause, and the use of birth control pills, estrogen, and progesterone effect the disease. It is very common for pregnant women to develop varicose veins during the first trimester. Pregnancy causes increases in hormone levels and blood volume which in turn cause veins to enlarge. In addition, the enlarged uterus causes increased pressure on the veins. Varicose veins due to pregnancy often improve within 3 months after delivery. However, with successive pregnancies, these abnormal veins are more likely to remain. Other predisposing factors include aging, standing occupations, obesity and leg injury.

How phlebology can help?

Phlebology is the field of medicine that deals with vein diseases. It has been an established medical specialty in Europe for 50 years, and serious interest in phlebology has developed over the last 15 years in the United States. American College of Phlebology was founded in 1985 and is the largest phlebology society in the United States. It was established to improve the standard of care related to disorders of the veins. Its members are physicians and other health care professionals with backgrounds from a variety of medical specialties, who share a common interest and expertise in vein diseases and disorders.

When and how are veins treated?

The most commonly asked questions are: Do veins require treatment and What treatment would be best? Veins that are cosmetically unappealing or cause pain or other symptoms are prime candidates for treatment. There are two general treatment options: conservative measures such as compression stockings, or "corrective" methods such as sclerotherapy, surgery and light source/laser treatment. In some cases, a combination of treatment methods works best.


Surgical techniques to treat varicose veins include ligation (tying off of a vein), stripping (removal of a long segment of vein by pulling it out with a special instrument), and ambulatory phlebectomy (removal of veins through tiny incisions). Surgery may be performed using local, spinal or general anesthesia. Most patients return home the same day as the procedure. Surgery is generally used to treat large varicose veins.

Radiofrequency occlusion

The Closure? Procedure is a treatment alternative to surgical stripping of the greater saphenous vein. A small catheter is inserted, usually through a needle stick in the skin, into the damaged vein. The catheter delivers radiofrequency energy to the vein wall, causing it to heat. As the vein warms, it collapses and seals shut. The procedure is generally done in an outpatient or in-office setting. It may be done under local anesthesia. Following the procedure, the catheter is removed and a bandage or compression stocking is placed on the treated leg. The Closure? procedure is FDA approved for the treatment of the greater saphenous vein.

Endovenuous laser treatment

Endovenous Laser Treatment is a treatment alternative to surgical stripping of the greater saphenous vein. A small laser fiber is inserted, usually through a needle stick in the skin, into the damaged vein. Pulses of laser light are delivered inside the vein, which causes the vein to collapse and seal shut. The procedure is done in-office under local anesthesia. Following the procedure a bandage or compression hose is placed on the treated leg. Endovenous Laser Treatment (EVLT ™) performed with a Diomed 810 nm laser is FDA-approved for the treatment of the greater saphenous vein.

Ambulatory phlebectomy

Ambulatory phlebectomy is a method of surgical removal of veins. This is usually done in the office using local anesthesia. Incisions are tiny (stitches are generally not necessary) and typically leave nearly imperceptible puncture mark scars. After the vein has been removed by phlebectomy, a bandage and/or compression stocking is worn for a short period.

Laser/Light Source Treatment

A variety of laser/light source treatments are available today. A light beam is pulsed onto the veins in order to seal them off and cause them to dissolve. Light-based treatment is generally used only to treat small veins. Treatments may be combined with sclerotherapy. Multiple treatments are usually required.


Sclerotherapy can be used to treat both varicose and spider veins. A tiny needle is used to inject the veins with a medication that irritates the lining of the vein. In response, the veins collapse and are reabsorbed. The surface veins are no longer visible. Sclerotherapy relieves symptoms due to varicose and spider veins in most patients. With this procedure, veins can be dealt with at an early stage, helping to prevent further complications. You may need anywhere from one to several sclerotherapy sessions for any vein region. Depending on the type and number of veins being treated you may have one to many injections per session. Generally, normal activities can be resumed after sclerotherapy. Medically prescribed support hose and/or bandages may need to be worn for several days to several weeks to assist in resolution of the veins. The procedure, performed in the doctor's office, usually causes only minimal discomfort. Bruising and pigmentation may occur after sclerotherapy. Bruising typically disappears within 1-2 weeks. Although pigmentation almost always fades, it can last for several months. Scarring and other complications are rare.

Duplex-Guided sclerotherapy

With this technique, sclerotherapy is done while the doctor visually monitors the vein on an ultrasound screen. This enables treatment of veins that can't be seen because they are below the surface of the skin and would otherwise require surgical removal.

What results can you expect?

With the evaluation and treatment methods available today, spider and varicose veins can be treated at a level of effectiveness and safety previously unattainable. Regardless which treatment method is used, its success depends in part on careful assessment of the problem by a knowledgeable phlebologist.
