A localized dilatation of the abdominal aorta, which enlarges like a balloon to more than 1.5 times its normal diameter, is called an abdominal aortic aneurysm. The greatest risk of abdominal aortic aneurysm is rupture of the aneurysm with hemorrhage resulting in death. Famous historical figures such as Albert Einstein, Charles de Gaulle and Chinese geologist Li Siguang all died from rupture of abdominal aortic aneurysms. Another serious complication of abdominal aortic aneurysm is that the thrombus attached to the inner wall of the aneurysm cavity is not strong and may fall off at any time, leading to lower extremity arterial embolism and ischemic necrosis of the limbs and even acute renal failure. The indications for surgery of abdominal aortic aneurysm: (1) the diameter of abdominal aortic aneurysm is greater than or equal to 5.5cm; (2) its diameter increases more than 0.5cm every six months during the follow-up; (3) symptomatic abdominal aortic aneurysm. Minimally invasive surgical methods for abdominal aortic aneurysm: Endovascular abdominal aortic aneurysm repair (EVAR), i.e., placing an overlying stent with an artificial blood vessel through a femoral artery puncture to strengthen the inner wall of the abdominal aorta, which is characterized by less trauma, avoiding open abdominal surgery, and being able to exclude the fatal bombs in the body.
