Abdominal aortic aneurysms occur mainly in older adults over 60 years of age, often with hypertensive disease and heart disease, but they are also occasionally seen in younger adults. They are more common in men than in women. The occurrence of abdominal aortic aneurysms is mainly related to atherosclerosis. Other rare causes are congenital dysplasia of the aorta, syphilis, trauma, infection, aortitis, and Marfan syndrome. The incidence of abdominal aortic aneurysm is higher in western countries, and in China, its incidence is increasing year by year with the change of people’s life and dietary habits. Once abdominal aortic aneurysm is diagnosed, it should be treated surgically. The previous surgical approach to treat abdominal aortic aneurysm is to make a 30 cm incision in the center of the abdomen. The aneurysm is dissected and the diseased vessel is replaced with an artificial vessel implant to re-establish the continuity of the abdominal aorta. The development of endovascular stenting has allowed the treatment of abdominal aortic aneurysms to avoid the painful and dangerous median laparotomy, which is a type of endovascular surgery (EndovascularSurgery). Therefore, there is no need for actual dissection or suturing of the vessels, so it has the advantages of small wounds, less blood loss, less pain, faster recovery, and other low invasiveness. The use of endovascular stents to treat abdominal aortic aneurysms has a number of advantages over conventional surgery. First of all, the open wound is a small wound on both thighs instead of requiring the implementation of a 30 cm open wound, and of course the recovery time after the surgery is significantly shorter, and the patient can be discharged from the hospital within a short period of time. Secondly, surgical blood loss, surgical cardiopulmonary complications, and surgical-related mortality are also significantly reduced. With endovascular stenting, the patient’s blood flow mechanics are not significantly altered because the entire aorta does not need to be clamped, and the pressure on the cardiopulmonary system is less, so the postoperative recovery of cardiopulmonary function is fast. At the same time, because the entire operation is performed in the cavity, the impact on other parts of the body is minimized, so the risk of surgery is reduced to one-third of that of open surgery. Of course, not all patients with abdominal aortic aneurysms are suitable for treatment with endovascular stents. At this stage of endovascular stenting, 50-70% of patients are suitable for stenting, and it is up to the vascular surgeon to decide whether the patient is suitable for stenting depending on the location and shape of the aortic aneurysm and the size of the vessel. However, with advances in medical technology leading to increasing advances in stent design, more and more aortic aneurysm patients will be able to use this less invasive treatment method in the future. This procedure has been successfully performed at our hospital with satisfactory results, rapid patient recovery, and significantly fewer postoperative complications than traditional surgical methods. Postoperative precautions for patients undergoing this treatment are to return to the hospital for regular checkups and to closely observe changes in the size of the aortic aneurysm and the position of the stent during a certain period of time. In case a stent is found to be displaced, endovascular reinforcement fixation should be applied.
