| 摘 要： | 目的探讨易形成前交通动脉瘤的血管模式。资料与方法将1081份正常磁共振血管成像(MRA)图像定义为一般国人脑血管形态类型,与49例前交通动脉瘤患者脑血管形态类型进行对照。结果49例前交通动脉瘤中一侧A1优势型45例(占87.76%),与正常国人一侧A1优势型和其他类型构成差异有统计学意义(P<0.0001)。其中左侧A1优势型(33例)约为右侧A1优势型(12例)的3倍,与一般人群左侧A1优势型与右侧A1优势型比(11.19%/3.98%)差异无统计学意义(P=0.952)。一侧A1优势型前交通动脉双侧大脑前动脉A2段起始部夹角测量有瘤患者夹角平均值为174.5°,无瘤患者平均值为113.45°,两夹角差异有统计学意义(t=14.198,P=0.002)。结论一侧A1优势供血与前交通动脉瘤的形成相关,造成前交通动脉瘤左右侧差异的原因是一侧A1优势型发育左右侧存在差异,双侧大脑前动脉A2段夹角增大更易形成动脉瘤。对发现的此种血管模式应随访。

| Abstract: | Objective To investigate artery model liable to anterior communicating artery aneurysm formation. Materials and Methods 1081 normal magnetic resonance angiography(MRA) image in two years were defined shape of cerebral in general crowds. 49 anterior communicating aneurysms patient's type of cerebral vessels were analysed compared to general crowds to investigate artery model liable to anterior communicating artery aneurysm formation. Results Of all the anterior communicating aneurysms,one-sided A1 segment do... |
