摘要： 目的 研究颈部CT增强扫描下不同平面颈内静脉与颈总动脉之间的解剖关系 。方法 选取我院2010年1月至2012年7月以来的颈部CT增强扫描资料，观察高位平面（甲状软骨上缘）、中位平面（环状软骨水平）的颈内静脉与颈总动脉之间的关系。结果 在高位平面，颈内静脉主要位于后位及后外位（78.6%-83.9%），与颈总动脉的关系主要是部分重叠（70.5%-71.4%），而在中位平面，颈内静脉主要位于前位及前外位（72.3%），与颈总动脉的关系主要是并行（56.2%-63.4%）。结论 颈内静脉穿刺选择在中位平面相对于高位平面能更好地提高穿刺成功率和减少穿刺并发症。

Abstract: Objective To investigate anatomic relationships between the internal jugular vein and the common carotid artery under CT enhancement scan at a different plane.Methods To collect the anatomic relationships between the internal jugular vein and the common carotid artery at the high plane（the upp-er edge of the thyroid cartilage）、median plane（the level of the cricoids ca-rtilage）in our hospital patients since January 2010 to July 2012,all patients were checked by CT enhancement scan. Results At the high plane,the internal j-ugular veins are mainly posterior and posterolateral position（78.6%-83.9%）,the relationships with the common carotid artery are mainly partially overlap（70.5%-71.4%）.While at the median plane ,the internal jugular veins are mainly anterior and anterolateral position（72.3%）,the relationships with the common carotid artery are mainly parallel（56.2%-63.4%）. Conclusion Operating the internal jugular vein cannulation at the median plane had higher success rate and reduced more complications than the high plane.
