Abdominal aortic ulcers may be asymptomatic; some patients may present with acute abdominal pain, and sudden death may occur in a few patients. Abdominal aortic ulcers occur most often as a result of atherosclerosis of the abdominal aorta, and may be associated with hyperlipidemia and hypertension in some patients. Some patients with abdominal aortic ulcers may not have any manifestations, but the ulcers are visible on imaging and are relatively stable. On the basis of abdominal aortic ulcer, abdominal aortic coarctation may occur, and the patient may experience sudden abdominal pain, which is particularly severe, and if it affects the renal arteries, it may lead to decreased renal function or even renal failure. If abdominal aortic dissection occurs on the basis of abdominal aortic coarctation, it can lead to sudden death, so it needs to be taken seriously. Patients with abdominal aortic ulcers should go to the hospital to clarify the severity of the condition, strictly control blood pressure, and standardize treatment under the guidance of physicians.
