Like all medical procedures, sclerotherapy does have some risks. Sometimes the incision may bleed and in rare cases infection is possible. The sclerosant can cause numbness in the area that was treated, and this numbness may take a while to go away. Pulmonary embolism (a blood clot in the lungs) is a rare occurrence. An allergic reaction to the dye used to help the interventional radiologist see clearly inside the body is possible but rare.
