How long does it take to fully recover after cerebral aneurysm clipping surgery, this can not be generalized, mainly depends on the cerebral aneurysm grading, clinically cerebral aneurysm grading 5 levels. 1.Grade 1 or 2 cerebral aneurysm: usually asymptomatic, or slight headache and dizziness, after rupture and bleeding, the effect of cerebral aneurysm clamping surgery is satisfactory, usually about 3 weeks can be recovered. 2.Grade 3 cerebral aneurysm: at this time, patients may have consciousness disorder, manifested as drowsiness, timely minimally invasive surgical treatment, postoperative active cooperation with the doctor’s treatment, the use of mannitol dehydration to reduce intracranial pressure, nimodipine prevention of cerebral blood vessels to maintain the balance of water and electrolytes, placed in the lumbar pool of the external drainage, if necessary, as far as possible, the intracranial blood and water discharged out of the body, to alleviate the symptoms of headache, after the treatment of the patients will be completely recovered in 1 month or so. 3.Grade 4 or 5 cerebral aneurysm: the patient’s degree of consciousness is deepened at this time, and the performance of coma, even if the cerebral aneurysm clamping surgery is actively carried out, the clinical effect is very poor, and the patient will be in coma for a long period of time, and the patient’s life will be threatened in a short period of time. When patients find cerebral aneurysms, they need to go to the hospital for cranial CT and cranial CTA examination in time, and actively cooperate with doctors for treatment to improve the quality of life and prognosis.
