A Tried and True Procedure
Sclerotherapy (pronounced sklair-o-THAIR-uh-pee) is a medical procedure that has been used since the 1930s to treat varicose and spider veins. As the standard of care, it is considered one of the safest and most effective treatments for removing unwanted leg veins.
The procedure involves injecting a solution directly into a vein, causing the treated vein to seal shut and fade from view over time. The treated blood vessel (vein) is then naturally resorbed by the body.
Commonly asked questions about sclerotherapy
What is sclerotherapy?
Sclerotherapy is a minimally invasive procedure administered by your healthcare provider to treat uncomplicated spider veins and uncomplicated reticular veins. The treatment involves the injection of a solution into affected veins.
What are spider veins?
Spider veins are very small, fine, red or blue veins that are less than 1 mm in diameter. They lie closer to the surface of the skin than varicose veins and may resemble a thin red line, tree branches, or spider patterns. Spider veins can be found on the legs and face and may cover a small or large area.
What are small varicose veins?
Small varicose veins, also known as reticular veins, are small blood vessels that measure between 1-3 mm in diameter and are also known as feeder veins. Small varicose veins can enlarge, as a result of increased pressure in the vein or from weakened vein valves. You may have only small varicose veins or both small varicose and spider veins at the same time.
What causes spider and reticular veins?
Some factors that may increase your risk of developing them:
Heredity. If other family members had varicose veins, there’s a greater chance you will too.
Age. The risk of varicose veins increases with age. Aging causes wear and tear on the valves in your veins that help regulate blood flow. Eventually, that wear causes the valves to allow some blood to flow back into your veins where it collects instead of flowing up to your heart.
Gender. Women are more likely to develop the condition. Changes in hormones due to puberty, pregnancy, menopause, or taking birth control pills may increase a woman’s risk of developing varicose veins.
Pregnancy. During pregnancy, the volume of blood in your body increases. This change supports the growing fetus but also can produce an unfortunate side effect — enlarged veins in your legs. Hormonal changes during pregnancy may also play a role.
Extra weight or obesity. Carrying extra weight can put additional pressure on the veins. Prolonged standing or sitting. Your blood doesn’t flow as well if you’re in the same position for long periods of time.
Other possible causes for varicose veins are ethnicity, posture, occupation, hormones such as estrogen and progesterone, primary valvular incompetence, and incompetent perforating veins.
