Ultrasound Guided Sclerotherapy
After the Venefit procedure has closed the main incompetent superficial veins, there are often refluxing tributary veins which must be dealt with, as these veins can be a source of symptoms and recurrence of varicose veins. Ambulatory phlebectomy is very effective in removing large, bulging varicose veins that are easily visible on the skin’s surface. For the refluxing tributary veins that cannot be seen on the skin surface, we use foam sclerotherapy for resolution of symptoms.
Foam sclerotherapy involves injection of a solution with ultrasound assistance into the diseased tributary veins causing them to shrink, close off and gradually disappear. Foam is created by mixing air with the liquid sclerosant (detergent) and it has several advantages to straight liquid sclerosant. The foam agent displaces the blood in the vein so the medication can be applied to the vein wall at full strength; this increased contact increases its effectiveness without increasing toxicity. Second, the foam is easily seen on ultrasound, allowing us to be very specific in targeting the refluxing tributary veins.
Foam sclerotherapy is performed in our office and the entire procedure takes just a few minutes to complete. Dr. Sharma uses the ultrasound to help locate the targeted vein and inject the foam agent directly into the vein. After the procedure, we recommend wearing compression stockings for 48 hours to promote healing. This is a non-invasive procedure with no down time; patient is allowed to return to regular activities immediately after the treatment.
