Injection therapy, such as sclerotherapy, may be used to put off damaged veins without the need for surgical treatment. Sclerotherapy can be performed in a doctor’s office and works like this:
With using a fine needle, the doctor simply injects an irritating chemical (the sclerosing agent) into the varicose vein.
Doctor may prescribe anesthesia to minimize risk of injecting sclerosing agent.
The sclerosing agent produces scar tissue inside the vein, which stop the flow of blood to that vein, shutting it down permanently.
You should be confirmed that injection treatment is especially useful for treating for varicose veins small one below the knee. It could also be useful in treating some cases of spider veins.
Sclerotherapy is not suitable for:
- Large varicose veins
- Varicose veins extending up to the groin
- People who are obese
After the procedure:
- There may be some effects and redness of the skin at the injection sites.
- Your doctor may apply a compression bandage to the area. You would need to wear this bandage for about three weeks.
- Walking is necessary in regular practice.
- Many people are able to return to work and daily chores within 24 hours, if not immediately.
Possible Complications of Sclerotherapy
Sclerotherapy is sometimes very successful, but not always. Each varicose vein may occur again and require treatment. Other complications include:
Blood can come out from the treated veins into the surrounding tissue, which develops brownish discoloration on the skin around the treated veins. This discoloration will finally fade in four to six months, however sometimes it takes as long as a year. In uncommon cases, the discoloration is permanent.
In rare cases, a tiny, depressed scar may look after treatment, or a blood clot may produce in a treated vein.
The process may leave a fine network of smaller varicose veins at the site where the larger vein was treated.
The chemical solutions taken in the process contain high concentrations of salt, which can temporarily arouse blood pressure. Solutions have lead allergic reactions in some people, but these are uncommon.
Need To Know:
Women who undergo sclerotherapy should not take oral contraception precautions for six weeks before and six weeks after this treatment, because of an increased risk of hemorrhage (bleeding).
