摘要
目的:探讨MSCTA(多层螺旋CT血管造影)评价颈总动脉分叉(CCAB)解剖价值。方法:回顾性分析2005年～2008年在我院行颈动脉MSCTA、结果正常的50例受检者图像。分别对其进行形态分型、测量CCAB的夹角及分叉高度。结果:CCAB形态中1类4例,占8%;2类26例,占52%;3类20例,占40%。CCBA夹角大多数在300～400之间,占55%;其中右侧占58%,左侧占52%。CCAB的高度78%在同一水平,22%的人不在同一水平,最大相差14mm。结论:应用MSCTA可以准确评价CCAB的解剖,为进一步分析其与动脉粥样硬化的发生、发展提供了一种简便易行的技术。
Objective：To estimate the value of MSCTA in the normal anatomy of common carotid artery bifurcation（CCAB）.Methods：50 patients the normal carotid MSCTA images were analyzed retrospectively.To classificate the CT manifestations,measuring the angle and height of CCAB.Results：4 cases in type 1（8%）,26 cases in type 2（52%）,20 cases in type 3（40%）,CCAB s angle lay between 30°～40°（55%）,which the right side amounting to 58% and the left side amounting to 52%.The bilateral CCAB＇s height were at the same level in 78% of cases, and 22% cases were not, the maximum difference was 14 mm. Conclusion： MSCTA can clearly demonstrates the normal anatomy of CCAB. It provides a new convenient method to investigate with atherosclerotic pathological change.
