Patient Zhang, female, 77 years old, came to our hospital a week ago with coldness, numbness and intermittent claudication in both lower extremities. Magnetic resonance angiography showed aneurysmal dilatation of the middle and lower abdominal aorta and bilateral common iliac arteries, 60 mm at the widest point of abdominal aortic aneurysm, and arteriosclerosis and segmental occlusion in both lower extremities. On the morning of October 31, an endoluminal abdominal aortic aneurysm isolation was performed in the catheterization laboratory. The patient was discharged from the hospital one week after the operation, and was able to get out of bed and take care of himself the next day. Abdominal aortic aneurysm is a localized or generalized dilatation of the abdominal aorta, 90% of which occurs below the renal artery. The etiology is mostly aortic atherosclerosis, followed by trauma, infection, congenital dysplasia, syphilis, and aortitis, etc. It is more common in elderly men over 65 years of age. Patients are mostly asymptomatic, and those who have symptoms are mostly pulsating masses around the umbilicus or in the middle and lower abdomen, dull pain or lumbago, localized pressure pain, and systolic murmurs can be heard. The developmental outcome is aneurysm rupture, and when the aneurysm diameter is >6 cm, the possibility of rupture is 72-83%. It is reported that the 5-year survival rate of abdominal aortic aneurysm is only 19%, and 63% of patients die from aneurysm rupture. With the continuous development of minimally invasive interventional techniques, significant developments have been made in the treatment of abdominal aortic aneurysms by transfemoral endoluminal aortic stent graft placement (endovascular isolation), especially for the interventional treatment of abdominal aortic aneurysms below the opening of the renal artery, which is replacing traditional surgical procedures. The principle is to release a graft consisting of an artificial vessel with a metal endoprosthesis into the abdominal aortic cavity via the femoral route to separate the aneurysm from the circulation and achieve endoluminal isolation. Compared with surgery, it has the advantages of no abdominal opening, less trauma, fewer surgical complications, and especially fewer nursing and hospital days, thus opening up a new field of clinical treatment for abdominal aortic aneurysms. share: with (document) 0[(getElementsByTagName(‘head’)[0] || body).appendChild(createElement(‘script’)).src = ‘//static.youlai.cn/js/youlai/ static/api/js/share.js?v=89860593.js?’]; microsoft 14112
