An aneurysm is a limited, permanent enlargement of an arterial vessel that exceeds 1.5 times its normal diameter. For example, if the abdominal aorta is normally no more than 2.0 cm, an enlargement somewhere in that segment of the vessel that exceeds 3.0 cm in diameter is considered an abdominal aortic aneurysm. It is one of the common vascular diseases in the elderly. With the improvement of people’s living standards and the increase of life expectancy of the population, aneurysms are becoming more and more common. People’s living standards are gradually improving, and people’s health awareness is gradually strengthening, and more and more people are having regular medical checkups. What to do with these patients? Many patients often do not think that they have no symptoms, so they are not in a hurry and should wait and see. In fact, this is very undesirable. Aneurysm is not a malignant tumor – cancer, as people often say. However, if it is not treated, due to the impact of blood flow and expansion of blood pressure every moment, it is impossible to shrink the aneurysm, but will only keep expanding and eventually burst like a balloon. Therefore, some people call aneurysm in the body a time bomb in the human body, and once it explodes, it will be life-threatening. Once the aneurysm ruptures, the chance of being saved is very small. Living and working with an aneurysm is like living with a bomb buried in the body, which is not only dangerous but also seriously affects the patient’s psychology and quality of life. On the other hand, according to research, the growth rate of aneurysm is not uniform, that is, it does not increase from 3cm to 3.5cm this year and from 3.5cm to 4cm next year, but it is not predictable, maybe the growth of aneurysm is not obvious in the first one or two years, but it suddenly grows rapidly and causes danger in some time recently. Since patients are followed up regularly and many of them are not able to keep up with the follow-up, the sudden increase of aneurysm is not detected in time and rupture is life-threatening. Once the aneurysm ruptures, the patient’s vital signs deteriorate rapidly within minutes to hours, often too late to take resuscitation measures, and he or she dies before being admitted to the hospital. In clinical practice, we often encounter such patients, who were found to have an aneurysm several years ago, without treatment and without any symptoms. The patient’s family members held our hands and begged us to save the patient, and we felt sympathy and regret when we saw their grief. If we had taken early measures to treat the patient, how could we have ended up in this situation? Vascular surgeons treat aneurysms based on the principle that surgery is the treatment of choice as long as the patient can tolerate it. Surgical treatment methods are divided into two types: traditional open surgery and interventional surgery. Conventional open surgery: It involves dissecting the chest or abdomen, blocking the blood vessels above and below the aneurysm (sometimes with extracorporeal circulation), removing the diseased vessel segment, and using an artificial vessel graft. The surgery is very traumatic, with much blood loss, slower recovery and more complications. For example, thoracic aortic coarctation or thoracic aortic aneurysm may lead to postoperative paraplegia due to ischemia of the thoracic segment of the spinal cord after open-heart surgery to replace the vessel. However, for abdominal aortic aneurysms or other limb aneurysms, as long as a physician with expertise in vascular surgery can control the blood vessels well, there will not be much surgical bleeding and the surgery is safe. Another surgical method is interventional surgery, which involves puncturing or cutting through a distant normal vessel under radiological imaging surveillance and putting a specially designed stent with membrane into the section of the aneurysm so that blood flow no longer enters the aneurysm cavity and no longer impacts the wall of the aneurysm to achieve the effect of isolating the aneurysm, also called intraluminal isolation. This method is a minimally invasive procedure that has been developed in the last decade or so and is very effective, minimally invasive and has a quick recovery. It can only be performed by hospitals with special equipment (angiography machines) and by vascular surgeons and radiologic interventionalists with specialized skills. In addition, the cost is higher due to the special materials. Many tragic clinical cases of delayed treatment tell us that aneurysms should be treated promptly when they are detected. With the development of interventional and other techniques, aneurysm surgery has become safer and less invasive. We have treated a 90-year-old patient with an aneurysm and the patient was safely discharged from the hospital after the procedure.
