The aneurysm can be fatal, so we should pay attention to it. The abdominal aorta is a large artery in the abdomen of the human body, above and below the belly button, and is the part of the human body where aneurysms are more likely to occur. Abdominal aortic aneurysm is a disease caused by the expansion and swelling of the abdominal aorta to a certain extent for some reasons. Although abdominal aortic aneurysm itself is a benign disease, it is very dangerous, just like a time bomb in the stomach, if it suddenly increases in size and expands to a certain level, it is likely to rupture and cause death. In fact, if the abdominal aortic aneurysm does not break, the mortality rate is still very low, but if the aneurysm grows to more than 5 centimeters, the annual risk of danger will be more than 10%, in fact, many such patients do not even have a chance to be rescued after the rupture of the abdominal aortic aneurysm. Moreover, early stages are easily overlooked because there are no symptoms or few atypical symptoms. As the aneurysm increases in size, other symptoms and dangers may appear. One such symptom is stomach pain, which is often a sign that the aneurysm is about to rupture or even has already ruptured when the stomach pain is severe. This kind of stomach pain is different from the normal stomach pain. It is a short-lasting tearing pain, which is like a hand tearing in the stomach. Sometimes the patient may feel a vague pain, which is an uncomfortable feeling produced by the enlargement of the mass. Because the symptoms are not obvious, 60% to 70% of abdominal aortic aneurysm patients are referred from other departments in the clinic, because when the stomach hurts, people first think of seeing the emergency department, internal medicine, surgery, etc. One way to check yourself is to feel your belly regularly. If you feel up along the belly button, you can usually feel a lump that beats in rhythm with the heart in thinner patients, and this is the early detection of aneurysm. However, if the patient can feel it by himself, the aneurysm is relatively large and needs to be seen urgently, while an experienced doctor can feel it when the mass is small. However, patients with abdominal aortic aneurysms should never do abdominal massage casually, as it may be life-threatening if the abdominal aortic aneurysm is rubbed and cracked. Usually, the main cause of abdominal aortic aneurysm is atherosclerotic degenerative disease, so the incidence is higher in elderly people and people with atherosclerosis sclerosis. There are also factors such as infection, immune deficiency, and trauma. It is recommended that people with a history of hypertension and atherosclerosis should have a color Doppler ultrasound examination, and if problems are seen, CT and MRI can be further investigated to confirm the diagnosis. It is important to remind that patients with aneurysms often have coronary heart disease, cerebrovascular atherosclerosis, cerebral infarction and other diseases at the same time, so before doing aneurysm examination, it is important to pay attention to do some corresponding examination of other important organs of the body. Once an abdominal aortic aneurysm is found, it is recommended to rush to the hospital and listen to the doctor’s advice. Small aneurysms can be treated conservatively first. The old traditional method of treating abdominal aortic aneurysms is open surgery to replace a section of the aorta with an artificial vessel. In recent years, the development of minimally invasive treatment in vascular surgery has been rapid, and most of them now use minimally invasive methods, that is, endoluminal repair techniques, in which a stent with a coating is installed in the aortic cavity, which, to use an analogy, is like replacing the inner tube of a bulging bicycle tire, such treatment is less invasive and has a faster recovery time.
