摘　　要：目的:分析脑动脉开窗(CAF)变异的颅脑血管CT造影(CTA)诊断,以提高临床对CAF变异的认识。方法:收集2017年3月—2020年12月西南医科大学附属中医医院行颅脑CTA检查有CAF变异患者的CT图像资料,分析CAF的发生率、发生部位及影像表现特征。结果:在2015例行颅脑CTA的患者中,有68例患者发生脑动脉开窗(70处,其中有2例患者存在2处开窗),其中颈内动脉1处(1.4%),大脑前动脉12处(17.1%),前交通动脉1处(1.4%),大脑中动脉3处(4.3%),椎动脉28处(40.0%),基底动脉24处(34.3%);裂隙样开窗28例,凸透镜样开窗12例,重复型开窗30例。结论:椎动脉开窗发生率最高,其次是基底动脉和大脑前动脉;裂隙型开窗在前循环动脉中最常见,重复型开窗主要见于椎动脉。Objective:To analyze cranial angiography(CTA)diagnosis of cerebral arterial windowing(CAF)variants in order to improve the understanding of cerebrovascular windowing variants by CTA examination.Methods:CT image data with cerebral artery windowing variant in hospitals performing craniocerebral CTA from March 2017 to December 2020 were collected and the incidence of cerebral artery windowing,its location,and its imaging performance characteristics were analyzed.Results:Of the 2015 patients with cranial CTA,cerebral arterial openings were found in 68 patients(70,including two patients with two openings),including 1 internal carotid artery(1.4%),12 anterior cerebral arteries(17.1%),1 anterior communicating artery(1.4%),three middle cerebral arteries(4.3%),28 vertebral arteries(40.0%),and 24 basilar arteries(34.3%).There were 28 fissure-like openings,12 convex lens-like openings,and 30 repetitive openings.Conclusion:The vertebral artery has the highest incidence of windowing,followed by the basilar and anterior cerebral arteries.Slit-type openings were most common in the anterior circulation arteries,and repetitive openings were seen mainly in the vertebral arteries.
