目的研究颅内囊性动脉瘤破裂的形态学危险因素。方法回顾性分析551例(共611个)颅内囊性动脉瘤的病例资料,以动脉瘤破裂作为最后评定指标,分为破裂组(341个动脉瘤)和未破裂组(270个动脉瘤),使用SPSS17.0统计软件包分析数据。结果两组之间动脉瘤长、瘤颈宽、载瘤动脉平均直径、载瘤动脉近端与动脉瘤长轴夹角(IA)、瘤体长与瘤颈宽之比(AR)、瘤体最大径与载瘤动脉平均直径之比(SR)、动脉瘤面积与瘤颈处动脉面积之比(S1/S2)、存在子瘤有显著差异(P<0.05)。多因素Logistic回归分析显示:瘤颈宽<1.7 mm(OR=2.318,95%CI=1.381~3.893,P=0.001)、存在子瘤(OR=12.512,95%CI=7.827~20.002,P<0.001)、S1/S2>2.1(OR=2.460,95%CI=1.408~4.300,P=0.002)为颅内囊性动脉瘤破裂的独立危险因素。结论动脉瘤长、瘤颈宽、载瘤动脉平均直径、IA、AR、SR、S1/S2、存在子瘤是动脉瘤破裂的形态学危险因素。
Objective To study the morphological risk factors of ruptured intracapsular aneurysm. Methods A retrospective analysis of 551 cases (611 cases) of intracranial saccular aneurysm cases, aneurysm rupture as the final assessment indicators, divided into rupture group (341 aneurysms) and no rupture group (270 aneurysms) , Using SPSS17.0 statistical package analysis of data. Results The length of the aneurysm, neck width, average diameter of the parent artery, the angle between the proximal end of the parent artery and the aneurysm (IA), the ratio of tumor length to neck width (AR), tumor size The ratio of the maximum diameter to the average diameter of the parent artery (SR), the ratio of the area of the aneurysm to the area of the artery at the neck (S1 / S2) and the presence of the tumor of the neck were significantly different (P <0.05). Multivariate logistic regression analysis showed that tumor size was less than 1.7 mm (OR = 2.318, 95% CI = 1.381-3.893, P = 0.001) ), S1 / S2> 2.1 (OR = 2.460,95% CI = 1.408 ~ 4.300, P = 0.002) were independent risk factors for ruptured intracapsular aneurysm. Conclusion The length of aneurysm, width of tumor neck, mean diameter of tumor-bearing artery, IA, AR, SR, S1 / S2 and presence of tumor are the risk factors of aneurysm rupture.
