Disorders of the Veins
The most common venous disorders treated by vascular surgery are varicose veins. This occurs when veins in the thighs and legs become enlarged and twisted. This is often caused by the failure of the one-way valve system in the veins, in which case it can be treated surgically by removing the segments of veins containing the malfunctioning valves as well as those veins which are significantly dilated.
