Abdominal aortic aneurysm requires close observation and drug control after surgery, and its sequelae include the following: 1, recurrence or internal fistula at the proximal, middle, and distal ends of the abdominal aortic aneurysm stent, caused by untreated etiology; 2, distal vascular occlusion or stenosis, caused by embolism or thrombosis in the distal area of the stent after abdominal aortic aneurysm surgery, especially after endoluminal stent placement. The manifestation is weakness of the lower limbs, and there may be serious ischemic disorders of the limbs; 3, sexual dysfunction, limb movement disorders, and skin sensory disorders.
