Varicose veins are gnarled, enlarged veins. Any vein may become varicose, but the veins most commonly affected are those in your legs and feet. That's because standing and walking upright increases the pressure in the veins of your lower body. The thickened, twisting or dilated parts of the vein are called varicosities.Varicose vein treatment, or endovenous ablation, is a simply invasive treatment that uses radiofrequency or laser energy to cauterize (burn) and close unusually enlarged veins in the legs, a condition called varicose veins. Normally, blood circulates from the heart to the legs via arteries and back to the heart through veins. Veins contain one-way valves which allow blood to return from the legs against gravity. If the valves leak, blood pools in leg veins which can become enlarged or varicose.Endovenous ablation is an image-guided method that uses heat generated by radiofrequency or laser energy to seal off these faulty vessels, diverting blood flow immediately to nearby healthy veins. Veins that have lost their valve effectiveness become extended, rope like, bulged, and thickened. These enlarged, swollen vessels are known as varicose veins and are a direct result of increased pressure from reflux. A usual reason of varicose veins in the legs is reflux in the thigh vein called the greater saphenous, which leads to pooling in the visible varicose veins below.This minimally invasive treatment is an outpatient process performed using imaging guidance. After applying local anesthetic to the vein, the interventional radiologist inserts a thin catheter, about the size of a strand of spaghetti, into the vein and guides it up the great saphenous vein in the thigh. Then laser or radiofrequency energy is applied to the inside of the vein. This heats the vein and seals the vein closed.What causes spider veins Varicose eczema usually occurs in the skin over and around varicose veins. It is caused by the faulty valves in varicose veins, which allow blood to flow in the wrong direction. Varicose eczema is also known as gravitational or stasis eczema. Like all types of eczema, the skin becomes dry and itchy. It is generally a slight annoyance and leads to no major problem. Most of the times there is no need for any kind of treatment and the problem subsides automatically.
