Sclerotherapy is a microinjection procedure to treat spider veins. The procedure involves injection of a sterile solution (called a sclerosing solution) into the small veins using a very fine, thin needle. This solution irritates the vein lining causing it to undergo fibrosis and eventually disappear. Multiple veins can be injected at each session. The sclerosing solution used may be one of several different types and its selection often depends on the size and location of the spider vein.

This procedure is usually done in the doctor's office. It does not require any type of anesthesia. There is minimal pain, though a topical anesthetic cream can be applied to the skin before the procedure to reduce any discomfort.

The spider veins are destroyed by injecting a small amount of a chemical in the vein. The common sclerosants are either glycerine, hypertonic saline or Sotradecol. These chemicals irritate the small vein and causes them to undergo fibrosis and eventually disappear, restoring a smooth appearance to the affected area.

Cosmetic sclerotherapy is most effective in treating the small superficial veins next to the skin, referred to as spider veins. When large veins (varicose veins) are treated with sclerotherapy along with ultrasound guidance, a stronger solution and a higher volume is required. Following the treatment for larger veins, compression hose stockings are usually recommended to be worn.

It varies from individual to individual but typically 2-4 treatments are required for the best results. In patients with milder cases, 1-2 will suffice.

Walking is highly recommended soon after the procedure. However, any high intensity sports should be avoided for the first 2-3 days.

There is a little sting associated with each injection. The burning sensation lasts few seconds. Most individuals tolerate the procedure well and do not require any type of anesthetic. The majority of patients claim that the procedure is much less painful than what they anticipated.

Absolutely nothing. Spider veins are small veins which are entirely cosmetic in nature. They do not form blood clots, they do not ache, and they do not cause swollen feet or pain.

Almost anyone with unwanted spider veins can be treated, except women who are pregnant or nursing. Other relative contraindications include those with skin infections, uncontrolled diabetes, fever, and history of deep vein thrombosis.

The injected site may appear bruised and swollen for a few days. Wearing of the ace bandage will help relieve the swelling and pain. The bruising usually disappears in 2-3 weeks. After the first 1-2 days, most patients can resume their normal activities.

Generally, most individuals have multiple spider veins, and only up to 10-15 injections can be done at one seating. Each treatment session lasts approximately 15 minutes. After the treatment, sterile dressings are placed over the injection site and the entire leg is covered with an ace bandage. The ace bandage is left on for 2-3 days until the patient returns to see the doctor.

No; treatment of spider veins with sclerotherapy is considered cosmetic in nature and the cost of treatment is not covered by any insurance companies.
