What Are Leg Veins?

Leg veins, otherwise known as spider veins; the very small thin, threadlike veins that lie close to the skin’s surface and are commonly red, blue, or purple in appearance. Spider veins can be hormonally induced and associated with pregnancy and menstruation. Spider veins grow from reticular veins, also known as “feeder” veins.

Causes of Leg Veins

Your circulatory system is composed of arteries and veins. Arteries transport oxygenated blood from the heart and lungs to the rest of your body. In contrast, veins transport blood back to your heart and lungs. Spider veins and varicose veins most commonly occur in the leg, in what are known as the superficial veins. This is because the veins in your legs are subject to large amounts of pressure and must work harder than other types of veins to transport blood upward to the heart, against the force of gravity.

Blood typically flows from superficial veins into deep veins, which are often connected by perforating veins. Normally functioning veins have uni-directional valves which prevent blood from flowing backwards in the vein, as it travels upwards toward the heart and lungs. If valves in the perforating veins or superficial veins do not work properly, some blood will be allowed to flow backwards, and collect in a pool below. As blood accumulates, it exerts increasing pressure on the walls of the vein, which causes them to weaken and become dilated, or stretched. As a result, spider veins or varicose veins form in the region.

Leg Veins Treatments

Sclerotherapy is a procedure used to treat leg veins, otherwise known as spider veins; the very small thin, threadlike veins that lie close to the skin’s surface and are commonly red, blue, or purple in appearance. Spider veins can be hormonally induced and associated with pregnancy and menstruation. Spider veins grow from reticular veins, also known as “feeder” veins.

Sclerotherapy is done by carefully injecting sclerosing solution into the unwanted vein. The solution causes the veins to collapse and fade. Multiple sclerotherapy sessions may be required to achieve desired results. There are a few rare risks involved with sclerotherapy, including inflammation, the formation of blood clots in the veins, and adverse allergic reactions to the sclerosing solution. As always consultations are recommended. The benefits of treatment can include cosmetic improvement as well as an increase in self esteem and confidence.
