Comparison of the efficacy and safety of interventional embolization at different time in the treatment of Hunt-Hess IV-V intracranial aneurysm hemorrhage

Objective To investigate the efficacy and safety of interventional embolization at different time in the treatment of Hunt-Hess Ⅳ-Ⅴ grade intracranial aneurysm. Methods One hundred and twenty cases of Hunt Hess Ⅳ-Ⅴ intracranial aneurysm bleeding from January 2016 to January 2018 were selected and treated in the Department of Interventional, Huanggang Central Hospital. According to the time of intervention, they were divided into early group ( 14 d), 40 cases in each group. Three groups of patients were treated with embolization, the treatment, safety and recovery of the 3 groups were compared. Results There was no significant difference among the 3 groups in the effective rate of interventional embolization (P>0.05). The incidence of adverse reactions in the 3 groups was statistically significant (P 0.05). After treatment, the recovery of the 3 groups improved with the passage of time, and the recovery of the early group was the best, the late group was the worst. Conclusion Although the time of interventional embolization can not directly improve the therapeutic effect for patients with intracranial aneurysm bleeding, it can effectively improve the recovery speed of patients and reduce the incidence of adverse reactions.
