A successful Laser vein treatment is dependent on proper evaluation of the leg veins.
The visual appearance of the lower extreme ties is a useful, but not always reliable, guide to the peripheral venous condition. Multiple factors contribute to varicose veins. Intrinsic pathological conditions combine with extrinsic environmental factors to produce a wide spectrum of disease. Heredity seems to be particularly important in determining susceptibility to primary valvular failure. Occupations that require prolonged standing can lead to chronic venous distention and secondary valvular incompetence at any level. Women seem to be more susceptible to this problem, most likely because vein walls and valves periodically become more distensible under the influence of cyclic increases in progesterone. Pregnancy is an important risk factor that causes varicosities through several mechanisms. Most important are circulating hormonal factors that increase the distensibility of vein walls and soften valve leaflets. Another factor is the increase in venous capacity the develops to accommodate a greatly expanded circulation blood volume. Age is an independent risk factor for varicosities because with advancing age the elastic lamina of the vein becomes atrophic and the smooth muscle layer begins to degenerate, leaving a weakened vein that is more susceptible to dilatation. Most patients with venous insufficiency have subjective symptoms of pain, soreness, burning, aching, throbbing, cramping, muscle fatigue, and restless legs.
