| Objective To study the risk factors of intraprocedural re-rupture of ruptured intracranial aneurysms.Methods A total of 678 patients with ruptured intracranial aneurysm that received intravascular embolization were included in this study, including 20 cases that suffered rerupture of intracranial aneurysm during the surgery. The risk factors for intraoperativererupture were analyzed by univariate and multivariate analyses. Results Vasospasm, atherosclerosis and aneurysm size were the risk factors for intraoperativererupture (P<0.05); however, sex, age, history of hypertension, history of diabetes mellitus, Hunt-Hess grade, characteristics of the aneurysmal neck, surgical procedure and surgical time were not significantly correlated with incidences of rerupture of intracranial aneurysm. Conclusion Vasospasm, atherosclerosis, and micro-aneurysm are the risk factors for rerupture of intracranial aneurysm during intravascular embolization. |
