Sclerotherapy is a widely used nonsurgical procedure that eliminates spider and varicose veins. Using an ultrafine needle, Dr. Mackey injects a sclerosing agent into the vein, which will cause them to dissolve and eventually disappear. Patients undergoing sclerotherapy generally experience very little discomfort and can return to work that same day. Often used as an alternative to surgery, sclerotherapy can reduce or eliminate spider and varicose veins in 1-6 treatments, depending upon the extent of the problem and patient compliance following the procedure.
