目的：探讨脑动脉成窗变异的CTA表现，提高对该血管变异的认识。方法：选取8例脑动脉血管成窗变异患者，根据其CTA表现，结合横断面原始数据、容积重建（VR）、多平面重建（MPR）、最大密度投影（MIP）等图像后处理技术分析脑动脉成窗变异的发生率、部位、形态、大小、分型、与毗邻的关系及合并的其他血管异常。结果：在382例接受64排螺旋CT血管成像造影的患者中检出8例（9处）为脑动脉成窗变异，发生率为2.36%（9/382），其中椎动脉成窗变异4处、基底动脉3处、大脑前动脉及前交通动脉成窗变异各1处。此8例患者中有7例均并发其他血管异常，1例为未并发其他畸形的单纯性动脉成窗变异。结论：64排螺旋CT血管成像可清晰、直观、多角度地显示血管成窗变异的部位、大小、形态及与毗邻的关系及其他血管异常的合并症，且是无创性检查，故在临床诊断中具有较高的价值。
目的：探討腦動脈成窗變異的CTA錶現，提高對該血管變異的認識。方法：選取8例腦動脈血管成窗變異患者，根據其CTA錶現，結閤橫斷麵原始數據、容積重建（VR）、多平麵重建（MPR）、最大密度投影（MIP）等圖像後處理技術分析腦動脈成窗變異的髮生率、部位、形態、大小、分型、與毗鄰的關繫及閤併的其他血管異常。結果：在382例接受64排螺鏇CT血管成像造影的患者中檢齣8例（9處）為腦動脈成窗變異，髮生率為2.36%（9/382），其中椎動脈成窗變異4處、基底動脈3處、大腦前動脈及前交通動脈成窗變異各1處。此8例患者中有7例均併髮其他血管異常，1例為未併髮其他畸形的單純性動脈成窗變異。結論：64排螺鏇CT血管成像可清晰、直觀、多角度地顯示血管成窗變異的部位、大小、形態及與毗鄰的關繫及其他血管異常的閤併癥，且是無創性檢查，故在臨床診斷中具有較高的價值。

Objective:To investigate the CTA manifestation of the variation of cerebral arterial fenestration so as to improve the understanding of the abnormal blood vessels.Methods:Eight cases of patients with the variation of cerebral arterial fenestration were selected and the incidence, position, shape, size and type of fenestration variation, and its relationship with the adjacent cerebral arteries and other complicated vascular abnormalities were analyzed based on its CTA expression and the combination with image processing technology such as the original cross-sectional data VR, MPR and MIP.Results:Eight cases with the variations of cerebral arterial fenestration were detected in 382 patients accepting 64 -slice spiral CT angiography and the rate was 2.36% (9/382), in which there were 4 cases occurring at vertebral artery, 3 at basilar artery, 1 at the anterior cerebral artery and 1 at the anterior communicating artery in the variation of the fenestration. Seven cases were complicated by other vascular abnormalities and one case with simple variation of the cerebral arterial fenestration was not complicated by other abnormalities in these 8 patients.Conclusion: The location, size, shape of the variation of cerebral arterial fenestration and its relationships with neighboring and other complications of vascular abnormalities can be clearly and intuitively displayed with multi-angle by 64-slice spiral CT angiography and the detection with it is noninvasive, and therefore it possesses a higher value in clinic diagnosis.
