摘　　要：目的分析颅内动脉瘤的形态学特征,探讨动脉瘤破裂的危险因素。方法回顾性分析356例动脉瘤患者,其中破裂组90例,未破裂组266例。测量瘤体长、瘤颈宽,计算瘤体长与瘤颈宽的比值(AR)、瘤体长与载瘤动脉直径的比值(SR),观察动脉瘤的形态、数量、部位以及载瘤动脉情况,研究以上指标与动脉瘤破裂的相关性。结果破裂组动脉瘤与未破裂组动脉瘤相比瘤体长、AR值、SR值、动脉瘤的形态、数目、发生部位、载瘤动脉情况有明显统计学差异(P<0.05),瘤颈宽无显著性差异。结论颅内动脉瘤的生长部位、数量、瘤体长、AR值、SR值、不规则形动脉瘤尤其合并子囊、大脑前动脉A1段变异、动脉粥样硬化是动脉瘤破裂的风险因素;瘤颈宽不是动脉瘤破裂的风险因素。Objective To investigate the risk factors of rupture of intracranial aneurysms by studying the morphological characteristics of intracranial aneurysms.Methods 356 patients with aneurysms were retrospectively collected,90 cases in rupture group and 266 cases in unruptured group.The length and width of the aneurysms were measured,the ratio of the length of the aneurysm and the width of the neck of the aneurysm(AR),the ratio of the aneurysm length and parent artery diameter(SR)were calculated,and the shape,number,location and the condition of the parent artery of the aneurysms were observed.The correlation between the above indexes and the rupture of the aneurysms was studied.Results The length,AR value,SR value,shape,number of aneurysms,location of aneurysms and the condition of parent aneurysms of ruptured aneurysms were significantly different from those of unruptured aneurysms(PV0.05),but the width of aneurysms had no significant difference(P>0.05).Conclusion The location,number,length,AR value,SR value,irregular aneurysms,especially with ascus,Al segment variation of anterior cerebral artery and atherosclerosis of intracranial aneurysms are risk factors for rupture of aneurysms,while the width of aneurysms are not risk factors for rupture of aneurysms.
