Alaysis Of Influence Factors Of Endovascular Complete Embolization For Intracranial Aneurysms

Objective : To analyze the risk factors associated with immediate angiographic results of intracranial aneurysms after endovascular treatment(EVT)for clinical treatment.Methods: A retrospective analysis of 546 patients with single intracranial aneurysm who underwent embolization from January 2013 to January 2017 in our hospital.The levels were divided into complete embolization group and non-complete embolization group according to the degree of embolization of intracranial aneurysms.Clinical and imaging data were analysed by univariate and multivariate models to determine with the associations of risk factors and complete embolization of intracranial aneurysms.Results: Univariate analysis showed that the rupture status,anatomical morphology,Hunt-Hess grade,aneurysm size and tumor neck width,different treatment regimen and aneurysm angle were statistically significant in patients with complete embolism group and incomplete embolism Group(all P <0.05).Multivariate analysis indicated that aneurysm size(OR = 0.344,95% CI: 0.204-0.578,P < 0.001),aneurysm rupture status(OR = 0.568,95% CI: 0.314-947,P = 0.030),treatment management(OR = 3.6989,95% CI: 2.223-6.153,P < 0.001)features of aneurysmal neck(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),aneurysm shape(OR = 1.689,95% CI: 1.118-2.552,P = 0.013)were independent risk factors of completely occlusion of intracranial aneuryam.Conclusion: Micro-miniature,un-ruptured,narrow-neck,small inclination angle and regular-shaped aneurysms,stent-assisted coiling and balloon-assisted coiling were more probable to be occluded completely.
