The clinical manifestations of abdominal aortic aneurysm usually include abdominal pain, rupture, and compression symptoms. 1. Abdominal pain: pain is the most common symptom of abdominal aortic aneurysm, and the throbbing mass usually appears around the navel, usually in the upper left position of the navel, and the rhythm of heart rate and the frequency of throbbing is more consistent. However, the feeling of this throbbing is more obvious in patients with thin body types, and it is more difficult for obese patients to feel it. 2.

When the abdominal aortic aneurysm ruptures, the patient’s abdomen and back will feel severe pain, and the phenomenon of low blood pressure will occur rapidly, which may be life-threatening in serious cases. 3. Compression symptoms: with the tension of the disease, the volume of the tumor will continue to increase, which will gradually compress the surrounding tissues and organs, thus triggering the symptoms of compression, and the reaction will be different depending on the location of the compression. It is recommended that when patients find abdominal aortic aneurysm, they should follow the doctor’s instructions to take treatment immediately. In daily life, patients should eat more nutritious food and pay more attention to rest.
