The legs contain a complex interconnected network of both superficial and deep veins, which during normal activity accommodate about 17% of the body's blood volume. Although dilated varicose veins do carry blood, they are not very efficient and are not necessary for adequate circulation. Often by the time varicose veins are large enough to be seen, the body has already started to establish an alternate more effective route for the blood to circulate back to the heart.

Varicose veins can be safely treated and/or eliminated without harming your legs. Venous circulation will actually be improved and any symptoms that defective veins may have caused will improve by helping restore normal venous volumes and pressure. In fact, the veins which are closed by the laser endovenous occlusion of the saphenous vein (LES-Vein©) procedure are superficial and collect blood only from the skin. They contribute very little overall to the major blood flow away from the leg, which occurs through the separate deep veins located well within the larger muscles of the leg.

When the damaged veins have been closed off from the circulatory system, the blood that was pooled in the varicose and spider veins is no longer stationary and stagnant. Without the stagnant blood engorging the varicose and spider veins, your legs should feel less tired and heavy, and any swelling you may have been experiencing should be reduced. In general, the removal of spider veins has a minimal effect on overall circulation but may improve local venous circulation in the area treated.
