Varicose veins is a common name that I’m sure many people have heard of or seen. Some people turn a blind eye to it, some people take it for granted, and some people talk about it. So what exactly are varicose veins and what should be done with them? Today we will talk about it briefly. In human blood circulation, blood is supplied from the heart to the periphery through the arteries, and the peripheral blood flows back to the heart through the veins. Veins play an important role in the body as a channel of blood return. When the pressure inside the vein rises for any reason and exceeds the tension of the vein wall, it leads to vein dilatation. If the venous hypertension is not corrected in time, the vein wall will be damaged, remodeled, distorted, dilated, or even formed into a mass, called varicose veins. Zheng The deep veins of human body are protected by the sheath of blood vessels, muscles and other tissues, so they can have dilated walls but rarely have varicose veins. People often refer to varicose veins as superficial veins, especially superficial veins of the limbs, which mainly occur in the lower limbs. The superficial veins of the lower extremities mainly include the small and large saphenous veins and their branches, which are present in the medial part of the lower extremities and the back of the lower legs. The root cause of varicose veins is venous hypertension, so what can lead to venous hypertension: 1, saphenous vein valve insufficiency, commonly known as “varicose veins”, saphenous vein valve destruction for different reasons, the loss of one-way valve function, resulting in blood reflux, the formation of saphenous vein hypertension, and then develop into varicose veins, at this time varicose vein” can be used as a disease name, 2, lower limb deep vein valve insufficiency, the deep vein valve is destroyed, the loss of one-way valve function, resulting in blood reflux, forming deep venous hypertension, high pressure venous blood through the traffic vein back into the superficial veins, resulting in superficial venous hypertension, forming varicose veins, at this time the “varicose veins” as a manifestation of deep vein valve insufficiency. 3.Deep vein thrombosis, after the formation of thrombus in the deep veins of lower limbs, the thrombus blocks the return flow of deep veins and causes high pressure in the deep veins, and the high pressure veins can only flow back into the superficial veins through the traffic veins, causing high pressure in the superficial veins and forming varicose veins, and the “varicose veins” at this time is a clinical manifestation of deep vein thrombosis. 4.Iliac vein thrombosis or iliac vein stenosis and occlusion. The formation of the entire lower extremity venous hypertension, including superficial veins, the formation of varicose veins, then the varicose veins can spread upward to the root of the thigh or even the lower abdomen, cut the blood flow rate upward. The formation of varicose veins at this time is also a clinical manifestation. 5, Buga syndrome, manifesting as the hypertension of the inferior vena cava system, including of course the superficial veins, can form varicose veins, often manifesting as bilateral, spreading to the lower abdomen, or even the upper abdomen, chest, blood flow direction upward. 6, Of course there are other causes such as various congenital malformations such as KTS (congenital limb venous malformation hypertrophy syndrome). The causes of varicose veins are different and the treatment is naturally different. For simple saphenous vein valve insufficiency, commonly known as “varicose veins”, the varicose veins can be removed by traditional high saphenous vein ligation and varicose vein stripping, minimally invasive high saphenous vein ligation and varicose vein laser endovenous treatment, and the latest high saphenous vein ligation and stripper varicose vein percutaneous transillumination Rotational excision, etc. For other cases, varicose veins as a manifestation, if simply removing the varicose veins, not only ineffective but even aggravate the swelling of the limb and even cause adverse consequences. Ultrasound or imaging of deep veins, iliac veins, and inferior vena cava is needed to determine the cause of the disease and then treat it accordingly. So, although varicose veins are “simple”, they should not be treated “simply”. The cause of varicose veins should be clearly defined and treated according to the disease. Only then can we get rid of the disease and avoid future problems!
