SCLEROTHERAPY

Sclerotherapy is a technique which is very effective in the treatment of unwanted leg veins. It involves injecting a solution into dilated and visible veins in order to cause them to scar on the inside. Once injected, the vein becomes 'plugged', blocking the flow of blood within it and therefore making it invisible. Because of the many connections between surface veins and deep veins, this does not lead to any significant circulatory problems. Normally a number of treatment sessions are required to obtain a good cosmetic result. Some varicose vein problems are best treated surgically and it is important for you to consult with Dr. Preston in order to arrive at an optimal treatment strategy.

What are Varicose Veins?
Varicose veins are veins which have enlarged and which do not circulate blood effectively. Some varicose veins may even allow blood to flow backwards inappropriately. Visible varicose veins belong to the superficial system of veins which is responsible for the return of about 10% of blood flow from the legs. Most of the blood (90%) is returned by way of the deep veins which are not visible. Varicose veins constitute a progressive problem which normally worsens with time. It can, however, be controlled by a well-planned treatment program.

What are Spider Veins?
Spider veins are simply small, dilated veins which are visible because of the superficiality in the skin: they may be blue, red or purple. These are very common and may be present with or without larger varicose veins.

What causes Varicose Veins?
The primary cause is heredity. If your mother or grandmother had varicose veins, it is more likely that you will also. If such is the case, preventative measures become very important. Factors known to aggravate varicose veins include pregnancy, heat, long periods of standing, and obesity. Healthy veins may become varicose if injured or inflamed.
