A limited enlargement of the abdominal aorta with a maximum diameter exceeding the expected normal abdominal aortic diameter by more than 50% is called abdominal aortic aneurysm (AAA). Epidemiological data show that when the diameter of abdominal aortic aneurysm is <4 cm, the annual growth rate is 1-4 mm; when the diameter of the aneurysm is 4-5 cm, the annual growth rate is 4-5 mm; when the diameter of the aneurysm is >5 cm, the annual growth rate is >5 mm, and the rupture rate of the aneurysm is 20%; if the diameter of the aneurysm is >6 cm, the annual growth rate of the aneurysm is 7-8 mm, and the eventual rupture rate of the aneurysm increases to 40%. The risk of ruptured abdominal aortic aneurysms is extremely high, with a mortality rate of 90%. Interventional endoluminal repair was initially attempted in high-risk patients who were not candidates for open surgery; now it is mostly used in patients with severe cardiopulmonary insufficiency and other high-risk factors; due to its minimally invasive nature, its indications are rapidly expanding and it has even started to replace traditional open surgery in low-risk patients.
