The vascular system is made up of arteries and veins. Arteries deliver oxygenated blood to all organs of the body. Veins return deoxygenated blood back to the heart and lungs. Unlike arteries, veins contain one-way valves that when functioning properly permit the flow of blood toward the heart at a very low pressure. When valves become damaged and fail to either open or close completely, blood flow is altered and pressure in the veins increases.These enlarged veins are commonly called spider veins or varicose veins. Spider veins are small red, blue or purple veins on the surface of the skin. Varicose veins are larger distended veins that are located somewhat deeper than spider veins.
Veins that are cosmetically unappealing or cause pain or other symptoms are prime candidates for treatment. There are two general treatment options for varicose veins: conservative measures, such as compression stockings, and "corrective" methods such as sclerotherapy, surgery and light source/laser treatment. In some cases, a combination of treatment methods works best. A variety of laser/light source treatments are available today. A light beam is pulsed onto the veins in order to seal them off and cause them to dissolve. Light-based treatment is generally used only to treat small veins. Treatments may be combined with clerotherapy. Multiple treatments are usually required. One has to be catious about one`s lifstyle, since it is a main cause of veins.
