A Brief History

The first documented use of foam sclerotherapy dates back to the 1940s when European doctors began experimenting with injecting a foam solution into veins to treat blood clots. Over time, the procedure was refined to treat varicose veins and has been used for decades. In the 1990s, foam sclerotherapy gained popularity in the United States as an alternative to surgical procedures for treating varicose veins. Vein Specialist Centers offers this effective treatment from top doctors in NJ and NY.

What Is Foam Sclerotherapy?

Foam sclerotherapy is minimally invasive and can be performed right in our clinic. It is a safe and effective alternative to surgery for treating varicose veins and spider veins. The foam solution used in the medical procedure combines a sclerosing agent with air or gas. A sclerosing agent is a chemical substance that is injected into a vein or other tissue to cause it to become inflamed and eventually scarred. The subsequent scarring helps to seal off the affected blood vessels or tissue, preventing blood flow within the unhealthy vein. Our vein specialists inject the foam solution directly into your affected vein, causing it to collapse and eventually be reabsorbed by the body. 


Varithena is a brand name for an FDA-approved foam sclerotherapy solution our vein specialists use to treat varicose veins. It contains a medication called polidocanol, a type of sclerosing agent injected into the affected veins to cause them to collapse and seal shut. Varithena has a unique microfoam formulation of tiny bubbles that allow it to spread more evenly throughout the vein. This can make it more effective in treating larger veins than traditional liquid sclerosing agents.

What Happens During the Procedure?

Our Vein Specialist Centers doctor will inject the foam solution into your affected vein using a fine needle. This displaces the blood in the vein, allowing the sclerosant to contact the vein wall directly.

The foam has a higher surface area than liquid sclerosant, allowing for more efficient treatment of larger veins. Your physician will use ultrasound guidance to ensure the accurate placement of the foam solution.

The procedure typically takes 30-60 minutes, depending on the number and size of veins being treated. The sclerosant causes the vein to collapse so that the body can absorb the diseased vein and redirect blood flow to healthy veins.

Is Foam Sclerotherapy Painful?

Foam sclerotherapy can cause some discomfort during and after the procedure, but it is generally not considered painful. The foam injection may cause a mild burning or stinging sensation, but this is well-tolerated and usually subsides within a few minutes. Some patients may experience cramping or a feeling of pressure in the treated area during the procedure, but this is also typically mild and temporary. After the procedure, patients may experience some soreness or tenderness in the treated area. However, this can usually be managed easily with over-the-counter pain relievers and should resolve within a few days.
