Abstract
Objective To compare the effectiveness and safety of ultra-early (< 24 h)and delayed (≥ 24 h ) endovascular embolization of ruptured intracranial aneurysms with systematic review. Methods PubMed,Embase,the Cochrane Library,VIP,Wanfang Data,and China National Knowledge Internet (CNKI)were retrieved according to inclusion,exclusion criteria and retrieval strategies,and the clinical literature of ultra-early and delayed endovascular embolization for the treatment of ruptured intracranial aneurysms were obtained. The Review Manager 5. 3 software was used to conduct Meta-analysis for good prognosis rate,postoperative mortality,and postoperative rebleeding rate. Results A total of 10 articles were included,9 of them were retrospective control studies and 1 was prospective control study. A total of 2 021 patients were enrolled,including 970 patients treated with ultra-early treatment;1 051 patients treated with delayed treatment. There was significant difference in the good prognosis rate (OR,2. 67,95% CI 2. 07 -3. 44,P < 0. 01)and the postoperative rebleeding rate (OR,0. 23,95% CI 0. 11 -0. 47)between the ultra - early embolization group and the delayed embolization group (all P < 0. 01). There were no significant difference in the mortality between the two groups (OR,0. 76,95% CI 0. 51 -1. 13,P = 0. 17). The subgroup analysis showed that there were significant differences in the good prognosis rate in the ultra-early group compared with the early group (< 3 d,OR,1. 98,95% CI 1. 33 -2. 95)and the middle and late group (≥3 d,OR,4. 66,95% CI 2. 21 -9. 81,all P < 0. 01). Conclusion Compared with the delayed group, ultra-early embolization of ruptured intracranial aneurysms may improve the good prognosis rate,reduce the rebleeding rate,and not increase the mortality after procedure at the same time. However,more high quality and large sample randomized controlled trials are needed to confirm them.关键词
