| 目的 探讨CTA对头颈部动脉开窗畸形的诊断价值,以及头颈部动脉开窗畸形与性别、动脉瘤的关系。 方法 回顾性分析1468例接受头颈部CTA检查的患者,均经常规扫描后行VR及MIP重建,分析CTA图像对于血管异常的显示情况,比较男、女性患者及是否合并动脉瘤的患者间头颈部动脉开窗畸形发病率的差异。 结果 1468例患者中,检出头颈动脉开窗畸形92例(92/1468,6.27%),其中1例存在4处开窗畸形,4例为2处病变。92例中共有99处开窗畸形,47处位于基底动脉(47/99,47.48%),21处位于大脑前动脉(21/99,21.21%),14处位于前交通动脉(14/99,14.14%),13处位于椎动脉(13/99,13.13%),4处位于大脑中动脉(4/99,4.04%)。99处开窗畸形中裂隙型35处,凸透镜型39处,重复型25处;71处两支开窗血管对称,28处两支开窗血管粗细不均。男、女性患者开窗畸形发病率的差异无统计学意义(χ2=0.05,P>0.05)。92例开窗畸形患者中,14例(14/92,15.22%)伴有动脉瘤,动脉瘤的发病率在有无开窗畸形患者间差异无统计学意义(χ2=0.99,P>0.05)。 结论 CTA能够准确显示头颈动脉开窗畸形的位置、形态和毗邻关系,头颈动脉开窗畸形与性别、动脉瘤无明显关系。 |

| Objective To observe the diagnostic value of CTA for intracranial arterial fenestration and the possible relationship with gender and aneurysms. Methods The image data of 1468 patients who underwent cerebral CTA examination were reviewed retrospectively. After conventional scanning, the VR and MIP images were reconstructed, and the vascular abnormalities of CTA were analyzed. The differences of the incidence of intracranial arterial fenestration between males and females, and in patients whether with aneurysm were compared. Results Of the 1468 patients who underwent cerebral CTA, intracranial arterial fenestrations were detected in 92 patients (92/1468, 6.27%), including 1 patient of 4 window deformities and 4 patients of 2 window deformities. Ninety-nine window deformities were founded in 92 patients, including 47 lesions (47/99, 47.48%) in basilar artery, 21 (21/99, 21.21%) in anterior cerebral artery, 14 (14/99, 14.14%) in anterior communicating artery, 13 (13/99, 13.13%) in vertebral artery and 4 (4/99, 4.04%) in cerebral middle artery. Of 99 window deformities, 35 were categorized as slit type, 39 as convex type and 25 as calabash type. Besides, 71 window deformities were symmetrical, and the rest 28 were asymmetrical. The difference of arterial fenestration incidence in male and female was not statistical (χ2=0.05, P>0.05). Among 92 patients with arterial fenestrations, 14 (14/92, 15.22%) associated with aneurysms, the incidence of aneurysm was not statistically different compared with patients without arterial fenestration (χ2=0.99,P>0.05). Conclusion CTA can precisely demonstrate the location and morphology of intracranial arterial fenestration. No obvious relationship between fenestration and gender or aneurysm is found. |
