General Information

What is foam sclerotherapy?
Using an injectable, foaming agent, foam sclerotherapy is a procedure designed to eliminate spider veins and varicose veins by irritating the lining of the unsightly or painful veins until they close up and fade away.

How does foam sclerotherapy work?
Similar to alternative types of sclerotherapy, foam sclerotherapy interrupts the bloodflow through the enlarged veins by causing scarring to the vein’s inner lining. When this occurs, the blood is re-routed through other, healthy veins and the problem vein contracts and eventually vanishes. Foam sclerotherapy is unique because instead of a liquid sclering agent, it uses a frothy foam that is created when two chemicals are combined in the syringe before injection. The foamy consistency helps the agent stick to the problem vein longer, allowing more effective treatment.

How does foam sclerotherapy compare to similar procedures?
With foam sclerotherapy, the active sclering agent stays in contact with the walls of the targeted vein for a longer time than a liquid agent can, which delivers treatment that is more effectual. Another benefit to foam sclerotherapy is that the foam is visible on ultrasound, so the placement, travel, and effectiveness of the treatment can be monitored in an accurate, non-invasive way throughout the procedure.

Who should consider foam sclerotherapy?
Many people afflicted with varicose veins or spider veins can undergo foam sclerotherapy. Because it is less invasive than surgical options, individuals who are unable or not prepared to have surgery may be able to find relief through sclerotherapy techniques. Patients who have certain blood disorders or cardiovascular conditions, or are pregnant, may not be candidates for this procedure, and should consult a doctor for more information.

How is the procedure performed?
Your specialist will begin by sterilizing and anesthetizing the treatment areas to ensure minimal discomfort and complications. Then, under ultrasound guidance, the specialist will inject the foaming agent into the problem veins and track the dispersing of the foam throughout the entire treatment area. The number of injections and the length of time required to complete the procedure depends on the size of the area being treated, but usually the process takes around 30 to 45 minutes.

What is the recovery like?
One of the benefits of foam sclerotherapy is the short amount of recovery time needed. Most individuals can resume their everyday activities right after their procedure, though compression stockings are often recommended for a week or so if the treatment was performed on the legs.

Are the results immediate?
Results are visible immediately after the procedure, and the foam will continue to treat the area for a short time after. Once a vein is treated the results are permanent. Some patients require multiple treatment sessions for the best results.

Are there any risks involved?
Side effects such as itching, redness, and bruising may occur in some patients, though they usually fade within a few days of the treatment. There is a possibility that foam sclerotherapy may involve an elevated risk of microembolisms, or small blood clots, but if this is a concern for you your specialist can provide additional information.

Has foam sclerotherapy been approved for use in the U.S.?
Yes, this procedure has been FDA-approved as safe for the treatment of spider and varicose veins in the United States.

Will my insurance cover this procedure?
If the treatment is motivated by a cosmetic concern, then it is typically not covered by insurance providers because they do not deem it medically necessary. However, if pain or other factors affect the patient’s lifestyle, the procedure may be covered. It is best to consult your specialist and your personal insurance plan for more information on the coverage you are eligible for.

What are the costs associated with foam sclerotherapy?
Foam sclerotherapy can range an average of $200 to $500 per treatment session, but can be more expensive depending on the area you live in, your provider’s fees, and the size and extent of the treatment area.
