ObjectiveTo investigate the effects of the vascular interventional embolization therapy at different time on the clinical effects and cognitive function of the patients with intracranial aneurysms.

MethodsThe clinical data of 63 patients with intracranial ruptured aneurysms were retrospectively analyzed, and the patients were divided into the early group(34 cases) and delayed group(29 cases) according to different operative opportunity.The Montreal cognitive assessment(MoCA) scale scores before and after operation, postoperative immediate embolization rate, incidence rate of complications, and GOS evaluation results after 3 months of postoperative following up were compared between two groups.

Results After operation, the complete embolism rate in early group was significantly higher than that in delayed group(P < 0.05).The scores of MoCA scale in two groups at all time points were lower than those before surgery(P < 0.05), and the scores of MoCA scale in early group were higher than those in delayed group(P < 0.05).The incidence rate of postoperative complications in early group was significantly lower than that in delayed group(P < 0.05).The results of GOS evaluation after 3 months of postoperative following up showed that the recovery of patients in early group was better than that in delayed group(P < 0.05).

Conclusions Early vascular interventional embolization therapy can significantly improve the clinical efficacy and prognosis of patients with intracranial ruptured aneurysms, and more effectively improve the postoperative cognitive function.It is conducive to the recovery of patients, and worthy of clinical reference and promotion.
