A vein's primary function is to return de-oxygenated blood to the heart to be pumped through the lung and become re-oxygenated. During walking, for instance, the calf muscles act as a pump forcing blood back to the heart. To prevent blood from flowing in the wrong direction or stagnating, veins utilize valves. If the valves fail (the primary cause of venous reflux) then backflow down the leg is permitted. Over time, this backflow results in veins becoming enlarged and varicose. Vein treatment thus must stop this refluxing to be successful. To accomplish this, treatment must stop the valve failure at its highest level. In the legs, veins near the surface drain into larger veins, called the saphenous veins, that then connect into the deep vein system behind the knee and at the groin. Damaged valves in these larger veins often contribute to backflow, allowing blood to enter surface veins, thus causing swelling, pain, twisting, aching and bulging veins. In addition to valvular dysfunction, other causes for varicose veins are genetics, pregnancy, occupation, in some instances trauma, previous clots and advancing age.
Gravity is the culprit. The distance from the feet to the heart is the furthest blood has to travel in the body. Consequently, those vessels experience a great deal of pressure. If vein valves can’t handle the pressure, the back flow of blood can cause the surface or superficial veins to become swollen and distorted.
Vein ulcers are areas of the lower leg where the skin has died and exposed the flesh below. Ulcers can range in size from a penny to completely encircling a leg. They are sometimes painful, odorous open wounds which leak fluid and can last for months or even years. Most ulcers occur when vein disease is left untreated. They are more common as age advanced but also can occur in teenagers.
The gold standard of any venous treatment is compression. This means compression or support garments. Medical grade compression hose with at least 20-30 mm mercury compression is necessary. These garments provide support for weak, incompetent and dysfunctional veins. In addition, leg elevation, routine exercise (which helps build muscle to aid in the “pump” action to help return blood) and weight control all will assist with vein disease.
A chemical injection, such as a saline or detergent solution, is inserted into a vein causing it to "spasm" or close up. Other veins in the area then take over its work. This procedure is most effective on smaller surface veins, less than 1-2 mm in diameter. Sclerotherapy may bring only temporary success and these varicose veins frequently recur.
ESES (pronounced SS) is an easy way to remember the conservative approach. It stands for Exercise Stockings Elevation and Still. Exercising, wearing compression hose, elevating and resting the legs will not make the veins go away or necessarily prevent them from worsening because the underlying disease (vein reflux) has not been addressed. However, it may provide some symptomatic relief. Weight reduction is also helpful. If there are inflamed areas or an infection, topical antibiotics may be prescribed. If ulcers develop, medication and dressings should be changed regularly. There are also potentially longer-term treatment alternatives for visible varicose veins, such as sclerotherapy and Closure techniques.
