The Vein Institute of La Jolla, Calif., has announced a research study investigating sclerofoam treatment of varicose veins in the United States. The Vein Institute would like to hear from physicians about their experience in using foam sclerotherapy to treat varicose veins.

Participants will be asked to fill out a standardized brief questionnaire.

John Bergan, MD, said foam sclerotherapy is increasingly becoming the best alternative to surgery and endovenous treatment of varicose veins. Its introduction in the United States is relatively recent, even though it has been practiced in Europe since 1990.

In using foam sclerotherapy, a sclerosant chemical detergent is changed into foam by mixing it with room air, he said. The foam is then injected into the vein under ultrasound guidance. Foam acts as a perfect contrast agent in ultrasound use.

“The foam actually damages the endothelium, stimulates smooth muscle contraction, which closes the vein and seals it shut,” Dr. Bergan said. “Because of its simplicity and pain-free application, it has significant advantages over other forms of endovenous treatment such as radiofrequency closure and laser ablation.

He said one of the advantages of foam treatment of varicose veins is immediate return of the patient to normal activity with no need for anesthesia and no pain or bruising.

The lower costs of the procedure and shorter procedure times are further advantages that he cites.

Finally, Dr. Bergan said the foam treatment can be used on patients who are not suitable candidates for any other endovenous treatment. For example, foam sclerotherapy is more appropriate treatment in patients who have non-Saphenous Vein reflux, tortuous or very small veins.

“We are asking physicians who use foam sclerotherapy in their practice to participate in our study,” Dr. Bergan said. “Please send contact information, center, estimated varicose vein patients treated per year and whether or not you are interested in exchanging experiences in some detail, in the form of a questionnaire.E-mail to This e-mail address is being protected from spam bots, you need JavaScript enabled to view it or call 858-550-0330.
