Spider Vein Sclerotherapy

How are spider veins eliminated?

Sclerotherapy is the ‘gold standard’ for eliminating spider veins and small reticular leg veins. For small, faint spider veins,  laser therapy may also be used.

Multiple injections of a foamed sclerosing agent are injected into the abnormal red, blue or purple spider veins of the involved leg. Injecting the unwanted veins with the sclerosing solution causes the target vein to immediately shrink, and then dissolve over a period of weeks as the body naturally resorbs the treated vein.

Prescription stockings should be worn for 1 week after treatment to ensure a successful outcome. Patients are encouraged to walk regularly every day during that time. The patient usually requires at least 2-3 treatment sessions separated by several weeks to significantly improve the appearance of their spider veins.

Are there side effects?

Side effects of treatment may include pain and swelling of the leg for a few days after injection. Rarely, brown hyperpigmentation or scarring may occur. In women taking estrogen-containing drugs, the formation of tiny, new blood vessels in the treated area can occur within a month after treatment but this usually resolves spontaneously by 6 months.  Cosmetic lasers can be used to treat these tiny vessels.

Will my spider veins return?

Usually the treated veins do not return. However, if you suffer from underlying venous hypertension or varicose veins, new spider veins may open up in the same areas after successful treatment. If this occurs, you should see a phlebologist, a specialist in venous disorders, who will examine your legs with duplex ultrasound . This test can determine if your deeper veins are involved. If they are, correction of the underlying problem may eliminate the spider veins.
