What is Sclerotherapy?

Sclerotherapy is derived from a Greek word that means ‘hardening’ is a kind of therapy that is used for treating varicose veins. In adults, when the veins present in the legs become twisted and swollen, such veins are referred to as varicose veins. When you wear shorts, it can be easily seen. They are also called ‘spider veins’. Sclerotherapy is done by injecting a chemical agent called sclerosing into the vein. The injection causes the veins to inflame and as a result, of it, scars are formed in the vein. The flow of blood is directed towards the healthier veins after closing the varicose vein.

During the treatment, the patient will experience mild pain for a minute or two. The treatment only lasts for 30 to 45 minutes. Some doctors make use of ultrasound sclerotherapy which requires usage of ultrasound technology to administer the solution precisely. Such kind of treatment will incur more sclerotherapy cost. When a person suffers from varicose veins, it should not be neglected and should seek medical assistance as soon as possible.

Sclerotherapy is a non-surgical procedure which is used to remove the varicose veins. Varicose veins are swollen twisted bluish or purple colored veins that are bulging out from the skin and sometimes there can be discomfort or pain in these veins. The sclerotherapy involves the injection of a solution directly in these veins. Due to the reaction of these injections, there is an inflammation reaction and this will lead to the walls of the veins to stay together which seems like the varicose veins shrink immediately. This also leads to fading and eventually then the disappearance of the veins.

Sometimes if there is a disease found in these veins then you might have to go through several treatments. There are also some spider veins which are treated effectively with the sclerotherapy treatment.

Foam Sclerotherapy

Foam Sclerotherapy is the new method which is used to treat large varicose veins as well as spider veins. There is a liquid sclerosing agent, which is mixed with the room air due to which foam is created and then this foam is injected into the affected varicose vein. The purpose of using this foam injection instead of the liquid injection is that foam covers the larger surface area.

Foam Sclerotherapy is used with the ultrasound imaging which shows up well and it becomes easier to track the foam and guide it to the affected area.

Possible Side Effects of Sclerotherapy and Foam Sclerotherapy

The simple Sclerotherapy side effects include bruising, lumps and burning sensation in the treated areas however it is only for few minutes and there are few precautionary measures to avoid these side effects. While the foam sclerotherapy includes some common allergies however there are also few people who are against it that through the foam, carbon dioxide is introduced in the body.

Other side effects are slight pains of the needle and bruises on the body which are common in both simple sclerotherapy and foam Sclerotherapy as in both treatments; the needles are inserted in the body.

Sclerotherapy Advantages

There are plenty of advantages of Sclerotherapy; few of these are given as under:

  • The first and foremost advantage is that it is a relatively inexpensive procedure than other surgical procedures.
  • The results of this treatment are relatively faster as it takes almost a week for the varicose veins to disappear.
