Frequently Asked Questions About Sclerotherapy


What is Sclerotherapy?

Sclerotherapy is an outpatient procedure that involves injecting a sclerosing liquid through a tiny needle into the spider or varicose vein. This solution replaces the blood in the vein and causes irritation and scarring of the walls of the vessel. The body then begins its natural healing process and the vein begins to shrink and disappear. Sclerotherapy is one of the most common treatments for spider and varicose veins and has been in use for more than 75 years.

Who is a Candidate?

Our physicians and staff will evaluate your varicose and spider veins. We will order a preliminary ultrasound (particularly patients with large bulging veins) to see if EVLT or ambulatory phlebectomy needs to be performed before the sclerotherapy. The treatment strategy is discussed in detail with each patient prior to starting therapy.

Describe a Treatment Session

The sclerosing agent is injected into the spider or varicose veins through a tiny needle. Discomfort is minimal and no anesthesia is required. You will need to bring support hose to your appointment.

What are the Risks?

Sclerotherapy has been proven to be remarkably safe. Reported complications, including overlying skin burns, nerve injuries, or blood clots developing in other untreated veins, are extremely rare. The risks are well below 1 percent; we have not seen these complications in our practice to date.

Do Insurance Companies Cover EVLT?

The overwhelming majority of insurance companies cover EVLT, ambulatory phlebectomy, and sclerotherapy for treatment of symptomatic varicose veins. But not all insurance companies will cover spider vein sclerotherapy. We will submit your information to your insurance company for preapproval prior to your treatment.
