It is possible that bilateral varicose veins in the lower extremities are related to the liver. In terms of the etiology of varicose veins, there are primary and secondary causes. The primary causes include saphenous vein valve insufficiency, blood from the deep veins enters the superficial veins through the poorly closed saphenous vein valves, which causes the venous pressure in the superficial veins to rise and the venous blood to stagnate in the superficial veins and not enter the deep veins in time, which leads to the dilatation of the superficial veins. Secondary causes include deep vein thrombosis, deep vein valve insufficiency and arteriovenous fistula. Chronic liver disease that causes hepatomegaly, compression of the inferior vena cava of the posterior hepatic segment, or formation of the inferior septum of the posterior hepatic segment, resulting in obstruction of venous return to the lower extremities can cause increased pressure and stagnation of blood in the venous system of the lower extremities bilaterally, when dilated and tortuous veins can often be seen on both sides of the lower abdominal wall, with blood flowing in an upward direction.
