Given above is the image of a dilated great saphenous vein right before it drains into the femoral vein at the superomedial aspect of the thigh. The dilated veins are referred to as varicose veins. The main reason why these veins dilate is valve incompetence leading to backflow of blood into the limbs. Factors such as constipation, pregnancy, weight lifting etc which increase intra abdominal pressure lead to poor emptying of limb veins and hence, promote the development of varicose veins. Treatment options involve use of compression stockings, laser ablation and surgical ligation and stripping.
