The aorta of the human body is the largest artery in the body, with a diameter of about 2.5 to 3.5 cm. It is connected to the left ventricle. When the heart contracts, it transports oxygen-filled blood to the whole body. The aorta can be said to withstand the pressure shock generated by the heart pump. first line. Therefore, the higher the blood pressure, the greater the pressure on the aorta. But human blood vessels are not like water pipes. They only have a single-layer structure. Too high blood pressure will stretch the aorta like a balloon, and the aorta with a three-layer structure will be repeatedly stretched open photo background removing under too high pressure. A tear occurs in the three layers of connective tissue in the blood vessel. The inner layer of the aortic blood vessel is damaged, and the blood goes to the wrong place and enters between the inner layer and the middle layer of the blood vessel wall, resulting in tearing of the inner layer and the middle layer of the blood vessel, which is the so-called aortic dissection. If even the outermost layer ruptures, it will cause immediate death. (Extended reading: Moment of life and death - aortic dissection ) What is the difference between aortic dissection and aortic rupture and aortic aneurysm? Sometimes people don't understand the difference between aortic dissection and aortic rupture or aortic aneurysm, but the three are very different. Complete tear or rupture of the aortic wall due to internal or external injury, which is called "aortic rupture"; "aortic aneurysm" is an abnormal expansion of the aortic vessel wall with a diameter exceeding 1.5 times the normal size , this condition will increase the risk of aortic dissection. What causes aortic dissection? Aortic dissection usually occurs when the aortic vascular connective tissue is abnormal, and there are many factors that can lead to abnormal vascular connective tissue. The various factors that may increase the risk of aortic dissection are listed below: Chronic high blood pressure (hypertension): Persistent and uncontrolled high
