摘要
目的通过CT血管造影(computed tomographic arteriography,CTA)方式回顾性研究中国人群升主及弓部血管的直径、长度特点;方法选择2006年9月至2007年9月接受胸主动脉CT血管造影的患者388例,使用GE公司AW4.2工作站测量升主、弓部、弓上分支的直径及长度数据,运用统计学软件进行分析。结果冠脉开口以上至左锁骨下动脉以远的主动脉直径D1-D6分别为(34±5)mm;(34±5)mm;(33±4)mm;(30±4)mm;(28±3)mm;(26±3)am。头臂干两处直径d1,d2也分别为(13±2)mm;(13±2)mm。左颈总动脉两处直径d3,d4分别为(8.7±1.5)mm;(7.9±1.0)mm。左锁骨下动脉两处直径d5,d6分别为(10.7±1.7)mm;(9.3±1.3)mm。冠脉开口处至头臂干动脉开口近端的主动脉管腔长度L.为(5.4±1.2)cm;头臂干开口近端与左颈总动脉开口近端之间的主动脉管腔距离L2为(1.3±0.4)cm;头臂干起始处至右锁骨下动脉开口处长度11为(4.0±0.8)cm;左锁骨下动脉起始处至椎动脉开口处管腔长度l:为(3.8±0.8)cm;头臂干与左颈总动脉管壁之间距离13,为(0.39±0.23)cm;左颈总与左锁骨下动脉之间管壁距离14为(0.7±0.5)cm。结论得到中国人群升主及弓部血管直径和长度的数据,可为腔内修复升主动脉及主动脉弓的各类研究提供数据支持。
