Abdominal aneurysm is abdominal aortic aneurysm, the typical manifestations are pain, abdominal throbbing mass, compression, rupture, embolization, the specific description is as follows: 1. Pain: mainly manifested as swelling pain or cutting pain in the lower back and abdomen, if sudden severe abdominal pain, often suggesting rupture of the tumor. 2. Abdominal throbbing mass: there is often a throbbing mass around the navel which is consistent with the rhythm of the heart, and the obvious one can be found in the process of checking, and usually the throbbing is not very obvious. 3. Compression: patients may have gastrointestinal compression symptoms such as abdominal distension and poor appetite; urinary system obstruction symptoms may occur when the ureter and renal pelvis are compressed; the compression of inferior vena cava may cause obstruction of venous return in the lower limbs; and the compression of biliary tract may cause obstructive jaundice. 4. Rupture: severe abdominal pain, hypotension, shock, myocardial ischemia and other serious manifestations will occur when the tumor ruptures. 5. Embolism: The blood flow in the cavity of abdominal aortic aneurysm is slow, which is easy to develop thrombus. If the thrombus is dislodged, the lower limb artery will be easily embolized, and acute limb ischemia will occur. When the above symptoms appear, you should consult the doctor in time to investigate the abdominal aneurysm and follow the doctor’s instructions for treatment.
