What is Secondary Varicose Veins in the Lower Limbs? Varicose veins refer to a condition where superficial veins are excessively dilated and tortuous, leading to stagnation of blood within the veins. It usually refers to varicose veins in the lower limbs. Varicose veins can be divided into primary varicose veins of the lower limbs and secondary varicose veins of the lower limbs. So, what exactly are secondary varicose veins in the lower limbs? Let's take a look below.
Secondary varicose veins in the lower limbs refer to the condition where varicose veins are caused by the formation of deep vein thrombosis in the lower limbs. The thrombus blocks the deep veins, causing an obstacle to blood return, and the superficial veins compensate for this blockage, resulting in varicose veins. Alternatively, it can also occur due to insufficiency of the deep venous valves in the lower limbs, where long-term reverse blood flow leads to venous congestion and increased pressure in the deep veins. Blood then flows backward through the connecting veins into the superficial veins, increasing the blood flow in the superficial veins and adding to their burden. Eventually, this leads to decompensation of the superficial veins, causing varicose veins in the lower limbs, known as secondary varicose veins in the lower limbs. In addition to the dilation, twisting, and protrusion of superficial veins in the lower limbs, patients often experience swelling, soreness, or pain in the affected limb.
