The blood vessels of the human body are spread throughout the body and are divided into two major systems: arteries and veins, which undertake the important task of transporting blood and nurturing life. The heart is the core, and the heart and blood vessels are closely linked in defending the health of our body. Therefore, the cardiovascular system of the human body is very important. In the fight against diseases, diseases of the cardiovascular system are most likely to be fatal or disabling, directly threatening the health of the human body and being the number one killer of human beings. Therefore, in order to defend our health, we can start by defending our cardiovascular system. The human heart is like a big pump, 24 hours of regular operation, the blood from the heart pump, blood along the artery flow to all parts of the body, to provide oxygen and various nutrients for the metabolism of tissues and organs, and some metabolic products of tissues and organs with the vein flow back to the heart, the heart will then pump these venous blood into the circulation of the lungs, and then there through the breathing of the lungs, the blood of carbon dioxide The heart then pumps these venous blood into the circulation of the lungs, and then there through the breathing of the lungs, the carbon dioxide in the blood is expelled out of the body, and the oxygen in the air is absorbed into the blood, and then the oxygen-rich blood returns to the heart, and the heart again pumps this fresh blood into the arterial vessels, and then flows along the arteries to the whole body, and this is the blood circulation. In the whole process of blood circulation, blood vessels are the bridge to transmit blood, and blockage or rupture of blood vessels will directly affect the blood supply of tissues and organs or human life. So what is vascular disease? What are the main aspects of vascular diseases? In terms of the occurrence of vascular diseases, there are mainly congenital diseases and acquired diseases. Congenital diseases are less common and are mainly diseases brought about by abnormal embryonic development, such as vascular malformations. Acquired diseases are the main diseases of vascular surgery and are very common, such as rupture of blood vessels caused by trauma, plaque in the arterial wall caused by atherosclerosis that causes narrowing of blood vessels, thinning of one part of the arterial wall that dilates and expands to form an aneurysm, and increased blood viscosity that causes vascular thrombosis and embolism, etc. These are generalized vascular surgical diseases, and these conditions often require surgical procedures or endovascular These conditions often require surgical or endovascular intervention to resolve. Of course, there are many other vascular surgical diseases, and all vascular diseases have different clinical manifestations.
