| 摘 要： | 目的分析破裂动脉瘤的大小、形态及瘤体长与瘤颈宽之比。方法对61个破裂动脉瘤的三维CT脑血管造影图像进行分析,测量动脉瘤的最大径,计算瘤体长与瘤颈宽之比,分析其形态特征,观察有无小泡样凸起和分叶状改变。结果动脉瘤的最大径平均为8.54 mm;78.8%的动脉瘤最大径<10 mm。动脉瘤的瘤体长与瘤颈宽之比平均为2.15;65%的动脉瘤其瘤体长与瘤颈宽之比>1.6。45.9%的动脉瘤有小泡样凸起或呈分叶状改变。结论最大径<10 mm的动脉瘤同样可能破裂;60%以上的破裂动脉瘤其瘤体长与瘤颈宽之比>1.6;小泡样凸起和分叶状改变在破裂动脉瘤中比较多见。

| Abstract: | Objective To evaluate the size,aspect ratio and configuration in ruptured aneurysms. Methods Three-dimensional CT angiogram of 61 confirmed ruptured saccular aneurysms were analyzed.The maximum diameter and aspect ratio were measured,and the configuration of the aneurysms were observed. Results The average maximum diameter was 8.54 mm,and 78.8% of the aneurysms were less than 10 mm in maximum diameter.The average aspect ratio was 2.15,and more than 65% of the aneurysms had an aspect ratio over 1.6.45.9% of the aneurysms harbored a bleb or were multi-lobular in shape. Conclusion Aneurysms less than 10 mm in maximum diameter are also easy to rupture.More than 60% of the ruptured aneurysms had an aspect ratio over 1.6.Bleb and multi-lobular change are common in ruptured aneurysms. |
