Due to the different parts of aneurysm, different sizes of aneurysm and different operation time, the sequelae after operation also vary. The common clinical aneurysms and their complications are as follows: 1. Cerebral artery aneurysm: if the surgery is performed before rupture occurs, there will not be obvious sequelae; if the surgery is performed after rupture occurs, the cerebral nerve may be damaged after the surgery, and sequelae such as hemiplegia, mental retardation, dizziness, numbness of limbs, blurring of vision, speech impairment, headache, etc., which may even lead to serious sequelae such as aphasia, impaired consciousness and cerebral hernia. 2. Disorders and serious sequelae such as cerebral hernia; 2. Abdominal aortic hemangioma: after surgery, there is a possibility of distal vascular occlusion, ischemia of lower limb limbs, even dysfunction, thrombosis of artificial blood vessels, intestinal ischemia and intestinal obstruction, renal failure, hydronephrosis and other serious sequelae; 3. Aneurysms in other parts of the body: after surgery, there is a possibility of thrombosis, local ischemia, aneurysm re-formation and other sequelae. After aneurysm surgery, we should avoid strenuous exercise, pay attention to rest, get enough sleep, live a regular life, combine work and rest, make self-psychological adjustment, eliminate tension and fear, eat regular meals, small amount of meals, keep the bowel movement smooth, and avoid forceful defecation.
