ABSTRACT
Objective To explore the impact of different times for endovascular embolization thera-py on the prognosis of elderly patients with intracranial aneurysm(IA)rupture and bleeding.Methods Clinical data of 156 elderly patients with IA rupture and bleeding admitted to our hos-pital from January 2019 to December 2022 were collected and analyzed retrospectively.All of them underwent intravascular embolization treatment.According to the timing of intravascular emboli-zation,they were divided into super early group(within 24 h from onset,n=66)and delayed group(in 24 h after onset,n=90).The Hunt-Hess grade,aneurysm location,cerebrospinal fluid exchange,embolization situation and success rate of embolization treatment were observed and re-corded.The prognosis of the two groups were evaluated with NIHSS score and mRS score.Results In terms of prognosis,no significant differences were observed in cerebrovascular spasm,disorders of consciousness,limb movement disorder,proportion of re-bleeding,and mRS score between the two groups(P＞0.05).The ratio of hydrocephalus was obviously lower in the super early group than the delayed group(4.55％vs 15.56％,P＜0.05).Though no statistical difference was seen in the pre-operative NIHSS score between the two groups(P＞0.05),the score was declined after treatment(P＜0.05),with that of the super early group notably lower than that in the delayed group(6.62±1.25 vs 7.82±1.35,P＜0.01).Conclusion Super early endovascular embolization can effectively reduce the incidence of hydrocephalus and improve neurological function in elderly patients with IA rupture and bleeding.
