Spider veins in the legs develop in persons who inherit the condition from their parents. Like their larger (varicose) counterparts, valve failure of these smaller veins allows blood to flow backward to the surface, a process called reflux, where they become enlarged and visible. Most of the time, nearby subtle, flat, blue-green (“reticular”) veins are the source of spider veins and should therefore be treated simultaneously.
While spider veins can cause leg discomfort, they do not lead to the more serious complications associated with varicose veins. However, the longer one postpones treatment the more new veins will appear, which will then require more treatments.
When many spider veins appear together at or near the ankle this is called “corona phlebectatica” and can be a sign of deeper “saphenous vein” reflux.
The most cost-effective treatment for spider veins is conventional sclerotherapy. This treats both the abnormal reticular and spider veins together. Finer veins can then be treated with the VeinWave.
