During this treatment for spider veins, the solution will be injected through a very fine needle directly into the vein. There may be some mild discomfort or cramping for a minute or two, especially if it is a larger vein. The sclerotherapy procedure will take 15 to 30 minutes.
Some blood vessels may have to be injected more than once, several weeks apart. After several sclerotherapy treatments, most patients see a 50 to 90 percent improvement. However, fading is gradual over a period of months. Elimination of spider veins is usually achieved, but similar veins may appear in the same general area.
You should be active and walk right after sclerotherapy. Some patients will be recommended to wear compression hose following vein treatment—especially if you spend a lot of time on your feet. Compression hose may decrease the number of spider vein treatments needed and the potential of recurrence.
