The aorta, the largest artery in the body, emanates directly from the heart and carries oxygen-rich arterial blood to all parts of the body. The aorta located in the thoracic cavity is called the thoracic aorta and extends down the left side of the spine to the diaphragm into the abdomen, which is called the abdominal aorta. The abdominal aorta mainly supplies blood to the lower half of the body and divides into bilateral iliac arteries at the level of the navel, which supply blood to both lower limbs and the pelvis respectively. The principle is like blowing up a balloon, once the diameter of the artery widens beyond the safe range, it may cause rupture and directly threaten people’s lives. Every year, about 200,000 cases of abdominal aortic aneurysm are diagnosed in the United States, of which about 15,000 are at risk of rupture; in recent years, the incidence of abdominal aortic aneurysm in China has shown an increasing trend, and statistics show that the incidence of abdominal aortic aneurysm is about 8.8% among people over 65 years old. Many patients will suddenly rupture the aneurysm without any symptoms, and the mortality rate of such aneurysm rupture can be more than 80-90%, therefore, the medical profession also calls abdominal aortic aneurysm a “time bomb” in human body. Fortunately, there are now efficient and safe means to diagnose, treat and even cure abdominal aortic aneurysms early before they become symptomatic.
