Conventional Sclerotherapy

Conventional Sclerotherapy

Conventional sclerotherapy is a process where a liquid (a irritating solution called a sclerosant) is injected into the vein which causes the vein to collapse. As time goes by, the collapsed vein will seal so that no more blood can flow through it.

Sclerotherapy has been used in the treatment of varicose veins for over 100 years, but only became relatively safe in 1946 with the invention of sodium tetradecyl sulfate (STS). And it has been perfected with the use of ultrasound (as seen in the picture). This treatment is sometime called “ultrasound guided sclerotherapy”.


Quick and somewhat less expensive

In comparison with surgery, the operation takes a lot less time. It takes only about ten minutes to perform. And no anesthesia is necessary.

But the success rate is not as high. More than one treatment is usually needed to seal a vein. So you may need to come back to the clinic many times before getting rid of your varicose veins. Taking this into account, conventional sclerotherapy should be use on small varicose veins below the knee, where other treatments would be more risky.

Like all other surgical treatments, sclerotherapy does not prevent new varicose veins from appearing in the future. You must include an additional approach (wearing compression stockings or taking supplements to strengthen your veins, for example) to have long term success.
