Treatment and Prevention
Compression hose are commonly used to prevent spider veins and decrease extension of existing spider veins. However, intervention is needed to eliminate spider veins that have already developed. Sclerotherapy is a technique in which a saline solution is injected into the vein, causing it to cave in. This normally takes several treatments and compression stockings are worn afterwards to prevent re-opening of the vessels.
