The success rate of surgery for abdominal aortic aneurysms is relatively high, probably around 95-98%. However, for patients who go to the hospital for surgery only after rupture of the aneurysm has already occurred, the success rate of surgery is relatively low, around 50%. Therefore, for patients whose abdominal aortic aneurysm is larger than 4cm in diameter, and whose aneurysm is found to have increased significantly in size upon review, it is generally recommended that surgery be performed as soon as possible. Do not wait until the rupture of the aneurysm, and then emergency surgery. Abdominal aortic aneurysm is an arterial dilatation disease, mostly caused by degenerative lesions of the arterial wall, such as atherosclerosis. Rupture of the aneurysm may cause severe abdominal pain, loss of appetite, and gastrointestinal bleeding, which can quickly lead to hemorrhagic shock, which is a serious threat to life and requires prompt treatment.
