Varicose vein surgeries
Varicose veins are an abnormal dilation of the veins, most often appearing in the legs. The essence of varicose veins is that the venous valves in the veins (especially in the lower extremities) do not function properly, hence blood cannot flow back to the heart effectively but instead begins to pool in the veins, leading to their dilation and the formation of the characteristic bulging and twisted varicose veins.
