Résumé
Objective To analyze the influence factors for complete embolization of intracranial aneurysms. Methods The clinical data of 546 inpatients with single intracranial aneurysm underwent interventional embolization at the Department of Neurosurgery,Anhui Provincial Hospital Affiliated to Anhui Medical University from January 2013 to January 2017 were analyzed retrospectively. They were divided into either a complete embolization group (n=255) or a incomplete embolization group (n=291) according to the immediate embolism degree of aneurysms. Single factor,multiple factors logistic regression analyses were used to analyze the factors associated with complete embolization of intracranial aneurysms. Results Univariate analysis showed that there were significant differences in the rupture status,anatomical morphology,Hunt-Hess grade, aneurysm size and neck width, different treatment regimens, and aneurysm angle between the patients in the complete embolism group and the incomplete embolism group ( all P<0. 05). The results of multivariate regression analysis showed that aneurysm size ( OR,0. 344,95%CI 0. 204-0. 578,P<0. 01),aneurysm rupture status (OR,0. 568,95%CI 0. 314-0. 947,P=0. 030), embolism ways (OR,3. 699,95%CI 2. 223-6. 153,P<0. 01),neck width of aneurysm (OR,0. 326, 95%CI 0. 198-0. 539,P=0. 003),aneurysm angle (OR,0. 647,95%CI 0. 451-0. 928,P=0. 018),and aneurysm morphology (OR,1. 689,95%CI 1. 118-2. 552,P =0. 013) were the independent factors of affecting the complete embolization of intracranial aneurysms. Conclusion Tiny, unruptured, narrow-neck, small inclination angle,regular-shaped aneurysms,stent-assisted or balloon-assisted embolization of intracranial aneurysms are easier to embolize the aneurysms completely.
