Sclerotherapy is an effective, minimally-invasive procedure used to treat some varicose veins and spider veins. It involves injecting a medication (sclerosing agent) into the vessel requiring treatment. This medication makes the vessel shrink and become less noticeable. It can be done with ultrasound guidance for larger varicose veins, or with small injection needles to treat superficial spider veins and reticular veins.
Why is sclerotherapy used?
Sclerotherapy is used to treat some varicose veins and superficial spider veins. It may also be used to treat venous reflux disease.
What to expect during and after the procedure
During the sclerotherapy procedure, a very small needle is used to inject a solution called a sclerosant (liquid or foam) into the vein requiring treatment. During the injection mild burning sensation or cramping may occur. The number of veins injected in one session varies depends on the size and location of the veins.
In most cases, patients will be able to resume all normal activities after treatment and do not need a recovery period after sclerotherapy. It is advised to stay active after your sclerotherapy treatment and walk at least 30 minutes per day for the next few days. This helps to circulate the medication and helps prevent stasis of blood which could cause blood clots. A follow up ultrasound may be recommended if larger varicose veins are treated with sclerotherapy and will be scheduled in 1-2 weeks after treatment.
Multiple sclerotherapy sessions may be needed to achieve desired results. These are usually scheduled several weeks apart. Medically prescribed compression stockings may need to be worn for several weeks to assist in healing. In general, spider veins respond to treatment in three to six weeks, and larger veins respond in three to four months.
