Abdominal aortic aneurysm mainly occurs in the elderly over 60 years old, often accompanied by hypertension and heart disease, but young people can also be seen occasionally. The high prevalence of abdominal aortic aneurysm and the danger: Abdominal aortic aneurysm belongs to the arterial local dilatation disease, which is the result of the abnormal dilatation and expansion of the arterial wall locally, and abdominal aortic aneurysm can be diagnosed when the diameter of the abdominal aorta is more than 3cm. The prevalence of abdominal aortic aneurysm accounts for 63%-79% of aortic aneurysms, most abdominal aortic aneurysms are caused by atherosclerosis, generally located in the distal renal arteries, extending to the bifurcation of the abdominal aorta, often affecting the iliac arteries, and occasionally located in the parts of the renal arteries above the thoracic and abdominal aortic aneurysms. Most abdominal aortic aneurysms are asymptomatic, and many patients discover a central pulsatile bundle in the abdomen unintentionally or during a physical examination. Therefore, regular aortic and peripheral arterial examinations should be performed for high-risk groups, such as the elderly, smokers, and those with atherosclerotic diseases. Pulse ultrasonography is the most simple, convenient, economical and non-invasive examination method. Early detection, early diagnosis and timely treatment can be realized. The most common complications of abdominal aortic aneurysm are: rupture of the aneurysm, embolization of distal organs and compression of adjacent organs. Abdominal aortic aneurysm is like a time bomb in the body, once ruptured, the mortality rate is as high as 50%-80%. Whether the abdominal aortic aneurysm can rupture is directly related to the size of the tumor diameter. Some studies show that: when the diameter of the tumor is less than 4 cm, the incidence of rupture is 10%; when the diameter of the tumor is more than 5 cm and less than 10 cm, the incidence of rupture is 30%-50%. When the diameter of the tumor is greater than 10 cm, the incidence of rupture is 80%. Therefore, the current clinical standard for surgical treatment is a tumor diameter of 5 centimeters. However, even if the tumor is small, acute rupture is still possible. Therefore, patients with abdominal aortic aneurysms should be operated on as soon as possible. Patients with small aneurysms should undergo regular imaging (e.g., ultrasound), and if there is a tendency for the aneurysm to increase in size, it is recommended that aggressive intervention be performed as soon as possible in order to reduce the rate of rupture of the abdominal aortic aneurysm and the mortality rate, and to improve the patient’s prognosis, so as to prevent the occurrence of serious consequences.
