Sclerotherapy is a process used to treat varicose or spider veins in a patient, usually affecting the legs. The procedure uses a chemical called sclerosant to minimize the affected veins. The drug is injected into the varicose veins and can take anywhere from five to 30 minutes depending on how many veins are being treated. Sclerotherapy is often done under ultrasound guidance so the physician can deliver and monitor the injection. Book an appointment today.
