摘要
目的探讨前交通动脉复合体变异的128排CT血管成像的影像表现及其与前交通动脉瘤发病的相关性。方法选择本院行CT颅脑血管成像的患者60例,其中前交通动脉瘤患者26例(研究组),无交通动脉瘤患者34例(对照组),比较两组患者前交通动脉及与其相连的A1段的造影表现差异,分析前交通动脉瘤的发病与交通动脉复合体变异的关系。结果①两组A1段形态表现主要为直线型和成窗形,其中直线型共54例(研究组24例,对照组30例),成窗型6例(研究组2例,对照组4例),两组A1段分型比较差异无统计学意义(P>0.05)。②两组共发生A1段变异21例,其中左侧优势14例(研究组10例,对照组4例),右侧优势7例(研究组2例,对照组5例),研究组A1段变异左侧优势发生率明显高于对照组及本组右侧优势发生率(P<0.05)。③研究组前交通动脉变异率明显高于对照组,两组差异有统计学意义(P<0.05)。结论 128排颅脑CT血管成像可以清晰显示前交通动脉复合体的变异情况,并且复合体的变异与前交通动脉瘤的发生有重要关系。
Objective To explore the 128-slice CT angiography of the anterior communicating artery complex variation and its correlation with incidence of anterior communicating artery aneurysm.Methods 60 cases of patients underwent CT brain angiography in our hospital were selected,26 cases（study group） with anterior communicating artery aneurysm,34 patients（control group） with no anterior communicating artery aneurysm,imaging performance of anterior communicating artery and anterior cerebral artery A1 part of two groups were compared,the relationship between anterior communicating artery aneurysm communicating and communicating artery complex variation was analyzed.Results ①A1 segment manifestations of two groups main were straight and the window-shaped,of which 54 cases（24 cases of study group,30 cases of control group） were straight,6 cases（2 cases of study group,4 cases of control group） were window-shaped,A1 segment type of two groups compared difference were not statistically significant（P 0.05）.②There was a total of the A1 segment variation in 21 cases,of which the left side advantages in 14 cases（10 cases of study group,4 case of control group）,the right side advantages in 7 cases（study group 2 cases,control group 5 cases）,the A1 segment variation incidence of the left side was significantly higher and the right side and control group（P 0.05）.③the anterior communicating artery mutation rate of the study group was significantly higher than control group,the difference was statistically significant（P 0.05）.Conclusion The 128-slice brain CT angiography can clearly show the variation of the anterior communicating artery complex,and the complex variation has an important relationship with the occurrence of the anterior communicating artery aneurysm.
