摘　　要：目的 探讨前交通动脉成窗变异的CT血管成像（CTA）表现及其临床意义.方法 回顾分析515例64排螺旋CT脑动脉CTA、346例脑动脉DSA、58例脑动脉MRA的图像资料,分析各类资料中前交通动脉成窗的检出率及影像表现特征.结果 脑动脉的CTA、DSA、MRA分别发现前交通动脉成窗变异11例、1例、0例.CTA发现的11例中9例为线型成窗（1例合并成窗部位动脉瘤）,2例为混合成窗,检出率为2.14%（11/515）.结论 64排螺旋CT脑动脉CTA对前交通动脉成窗变异的检出率与文献报道尸检的检出率相仿,明显优于DSA和MRA.Objective To study CTA features and its clinical value of fenestration of the arterior communicating artery. Methods The data of 6.1 slice spiral CT cerebral CTA in 515 cases,cerebral DSA in 3,16 patients and cerebral MRA were analysed. The detec ring rates of anterior communicating artery fenestration by CTA, DSA and MRA were analysed and imaging characteristics were also analysed. Results Aterior communicating artery fenestration was found in 11 cases, 1 case and 0 case by CTA,DSA and MRA, respectively. In 11 cases with fenestration of the anterior cerebral artery found by CTA, 9 cases were linear pattern （1 patient with an eurysm） and 2 cases were complex pattern,the detecting rate was 2.14%（11/515）.Conclusion Tbe detecting rate of anterior communicating artery fenestration with CTA in this study comes to the same as literatures. CTA is superior to DSA and MRA in detecting tbis arterial variation.
