Doctors use vein sclerotherapy to treat varicose veins and spider veins. This procedure is also called injection therapy, and each treatment session normally lasts from thirty to sixty minutes. Varicose veins appear most frequently in females aged thirty to fifty, however anyone can be affected. If you are pregnant, obese, have hormonal issues, or have a natural propensity to develop varicose veins, you are more prone to the condition.
The veins in healthy legs contain several valves, which move the blood upwards. As the blood makes its’ way towards the heart, it travels against gravity. If the valves malfunction in some way, blood might pool — and this creates problems. Once the veins in your legs have blood pooling, the pressure inside them rises. This weakens the walls of the veins. This causes the veins to become twisted and enlarged. Spider veins form near to the skin’s surface and typically, they have a circular appearance.
During vein sclerotherapy, a fluid (normally a saline solution) is injected straight into the spider vein or varicose vein. This solution aggravates the vein wall interior. As a result, the vein closes itself off. Then, the blood which would otherwise pass though this vein gets redirected, into a vein that is healthy. After the vein shuts off, it will slowly degenerate and become less pronounced.
