Sclerotherapy Treatment 

Spider and Varicose Vein Treatments in Vancouver, Burnaby & Coquitlam, BC

For many people, varicose veins and spider veins are simply a cosmetic concern. For other people, varicose veins can cause aching pain and discomfort. Sclerotherapy is the gold standard of treatments. World-renowned for cosmetic improvement of spider/reticular leg veins, sclerotherapy is the treatment of recommendation and choice. Also, sclerotherapy can reduce symptoms and improve the look of the skin.

What is Sclerotherapy?

Leg vein conditions such as spider veins and varicose veins may be unsightly and annoying, but they rarely pose a serious health threat. Spider and varicose veins are an inherited (genetic), weakness in the vein wall. Hormones, pregnancy, leg injuries, abdominal straining, and occupations that require standing, all contribute to the development of spider and varicose veins, as we age.


How does the treatment work?

Sclerotherapy uses an injection of a special chemical (sclerosant) substance, into a varicose vein, to damage and scar the inside lining of the vein. This then causes the vein to close. During this procedure, the affected leg is elevated to drain blood, and the sclerosant is injected into the varicose vein. The procedure is done in a doctor’s office or clinic, and takes approximately 5 to 30 minutes, depending on how many varicose veins are treated, as well as how big they are. After the injection of sclerosant is given, pressure is applied over the veins to prevent blood to return, when you stand up. You may need to wear compression stockings for several days or weeks to maintain the pressure. The sclerotherapy injection may be painful, and the chemical (sclerosant) that is injected can cause a feeling of burning or cramping for a few minutes, in the area where the shot was given. You may require multiple sessions depending on the extent of the varicose veins, and the type of sclerosant used.

Avoid exposing your legs to the sun for the first 2 weeks after the procedure.You will probably have to wear compression stockings for a short time after having sclerotherapy.

What are the side effects of sclerotherapy?

What are the side effects of sclerotherapy?

The most common side effect is skin colour change, along the treated vein. The discolouration may take 6 to 12 months to disappear.

Itching, bruising, pain, and blistering may occur where the veins were treated.

Scarring may happen, if ulcers or skin/fat necrosis forms around the treated vein. This would happen if sclerosant is injected outside a vein, or sclerosant escapes through the wall of a weakened vein.

A mild or severe (anaphylactic) reaction to the sclerosant. (Severe reaction is very rare.)

Blood clots or damage in the deep vein system.

Failure of treatment to prevent varicose veins from returning.
