To determine if you have an abdominal aortic aneurysm, you can perform a self-test by localized touch. The abdominal aorta is one of the thicker main blood vessels in the body and is located deeper in the abdomen. If dilatation of the abdominal aorta occurs, it can lead to aneurysmal dilatation and develop into an abdominal aortic aneurysm in severe cases. If the patient with abdominal aortic aneurysm is thin and underweight, a pulsatile mass can be palpated in the abdomen. If you feel it carefully, you will find that the frequency of the beat is consistent with the frequency of the heart. Once you touch and find a pulsatile mass in the abdomen, it is recommended to go to the vascular surgery department of a regular hospital as soon as possible, such as abdominal ultrasound, to further diagnose whether it is an abdominal aortic aneurysm. After the diagnosis is confirmed by the professional doctor, the patient should cooperate with the doctor to formulate the surgical treatment plan in time, so as to avoid rupture of abdominal aortic aneurysm, which may bring danger to the patient’s life.
