Secondary causes of varicose veins include deep vein thromboses (DVT), deep venous obstructions, superficial thrombophlebitis, congenital or acquired arteriovenous fistulas, and pressure on the veins in the abdomen during pregnancy or from a tumor.[3,5] According to Matfin,[5] thromboses in the deep veins, the most common cause of secondary varicosities, increase the pressure in the deep veins, which drain about 80% to 90% of the superficial veins. As a result, an obstruction in the deep vein causes a progressive dilation in the superficial veins that leads to varicosities (Figure).[5]
