There are many different treatments for getting rid of unsightly spider veins on the body and especially on the legs but one of the most effective ways is with sclerotherapy. Let me explain. In sclerotherapy, your doctor takes a liquid which is a sclerosant and with a very tiny little needle, painlessly injects it inside the spider vein. That medicine, the sclerosant, causes the spider vein to become swollen and irritated and when that happens it becomes sticky. After your treatment the doctor takes a compression bandage and puts it against the skin on top of the spider vein and it pushes the two sides of the spider vein together like this. But because the sclerosant has caused it to become sticky from inflammation, the two sides stay stuck together. If that happens, the blood can’t flow and when blood can’t flow through a spider vein, the spider vein dies and it just goes away. It’s a little bit analogous to putting glue in a garden hose and then stepping on the garden hose. The two sides get stuck together and then water can’t flow through it. What you need to know about sclerotherapy, besides the fact that it’s very effective and very safe, is that it’s painless, it’s done in the doctor’s office, and other than wearing the compression bandages and compression stockings for two to three days, it’s a very, very simple way to get rid of your unsightly spider veins.
