The abdominal aorta is the largest artery in the body and is primarily responsible for the blood supply to the intra-abdominal organs and both lower extremities. Abdominal aortic aneurysm is a limited bulge formed by the loss of normal integrity of the arterial wall structure due to atherosclerosis, infection, necrosis of the middle layer of the artery or congenital factors, and local expansion and deformation under the action of intra-arterial blood pressure. An abdominal aortic aneurysm is formed when the diameter of the distended abdominal aorta exceeds more than one times the normal diameter. Although abdominal aortic aneurysm is not a real tumor, it is more harmful than various malignant tumors. Once the tumor ruptures, it can lead to death in a short time. About 50% of patients are already incurable before they reach the hospital, and even if they can successfully enter the operating room, the success rate of surgery is less than 50%. Currently, the incidence of abdominal aortic aneurysm is about 8.8% among people over 65 years of age in China, and the rate of male patients over 60 years of age is as high as 80%. Hypertension, cardiovascular disease and smoking are the main causes of the disease. Dr. Mark Alan Adelman, chief of cardiovascular and vascular endovascular surgery at NYU Langone Medical Center, told us, “Although abdominal aortic aneurysms can be very scary to rupture and have no symptoms, they can be easily detected. With regular physical exams, doctors can feel the presence of an aortic aneurysm by applying firm pressure to the abdomen, and in thinner patients, the aneurysm can even be visibly seen to be beating. Early detection and timely treatment are therefore critical to saving the lives of patients with abdominal aortic aneurysms.” According to Samuel R. Money, a member of the American College of Surgeons, “When a suspected aneurysm is detected, prompt abdominal aortography and CT examinations are performed to help diagnose the size and extent of the aneurysm and the treatment modality. Even in small aneurysms, there is a possibility of acute rupture. Therefore, once an abdominal aortic aneurysm is confirmed, early intervention is imperative.” Abdominal aortic aneurysms are not curable with medications, and surgery is the only effective treatment for aneurysms. Minimally invasive endoluminal repair can be curative by introducing a stent into the artery with the aneurysm, isolating the blood flow from the aneurysm sac and wall, so that the blood flows through the stent and no longer impacts the aneurysm sac. Patients with abdominal aortic aneurysms must be detected early, treated early, and isolated early, and can live just as well with the aneurysm.”
