Aneurysms vary in post-operative sequelae due to different sites of occurrence, different sizes of aneurysms, and different times of surgery. The common clinical aneurysms and their complications are as follows: 1. Cerebral artery hemangioma: If the surgery is performed before the rupture occurs, there are usually no obvious sequelae; if the surgery is performed after the rupture occurs, there is a possibility of cerebral nerve damage after the surgery, with sequelae such as hemiplegia, mental retardation, dizziness, limb numbness, blurred vision, speech disorder, headache, etc., which may even lead to aphasia, consciousness Aneurysm of abdominal aorta: after surgery, serious sequelae such as distal vessel occlusion, lower limb ischemia and even dysfunction, artificial vessel thrombosis, intestinal ischemia and intestinal obstruction, renal failure and hydronephrosis may occur; 3. Aneurysm of other parts of the body: after surgery, sequelae such as thrombosis, local ischemia and aneurysm re-formation may occur. After aneurysm surgery, avoid strenuous exercise, pay attention to rest, get enough sleep, have a regular life, combine work and rest, make self-psychological adjustment, eliminate tension and fear, eat regular meals, have small and many meals, keep bowel movements smooth and avoid forceful defecation.
