Early symptoms of abdominal aneurysm may include abnormal throbbing sensation, pain, epigastric discomfort, arterial embolism, jaundice, difficulty in urination or vomiting of blood, etc. There is no such thing as the top 10 symptoms. 1. Abnormal pulsatile swelling, often located in the umbilicus or left above the umbilicus can be palpable round-like swelling, which is consistent with the heartbeat. 2. The pain is often a swelling or cutting pain in the abdomen, waist and back. Because the aortic aneurysm can compress and erode the vertebrae, the nerve root pain is caused. 3. The gastrointestinal tract is often compressed by the abdominal aneurysm, which will cause distension and discomfort in the epigastrium and decrease in the quantity of food; if it is compressed to the bile duct, it will cause obstructive jaundice; if it is compressed to the urinary system, it can cause obstruction of the renal pelvis or ureter, which will cause difficulty in urination, and the inability to discharge water will cause oedema of the lower limbs, eyelids and other places. 4. Abdominal aneurysms often have thrombus or atheromatous plaques, which may cause arterial obstruction in the distal limbs once dislodged. 5. If there is vomiting of blood, there may be abdominal aneurysm-digestive tract fistula, which is often preceded by vomiting of blood or blood in the stool. If any of the above situations occurs, please consult a doctor in time for reasonable and standardized treatment.
