腘动脉分支解剖及变异的CTA研究
发布时间:2021-03-09 02:09
目的:利用下肢动脉CTA分析中国天津地区人口胭动脉分支的解剖及变异特点,为临床手术及介入治疗提供影像学和解剖学帮助。材料和方法:回顾性分析2009.8至2013.4期间于天津市天津(天和)医院放射科行下肢CTA检查的807例患者的影像资料(男587例,女220例,共计1614支下肢CTA图像),中位年龄67岁(18-92岁),使用VR、MIP等图像后处理方法观察入组病例的胭动脉分支及变异情况,总结胭动脉分支解剖及变异类型,统计各类型的发生率。测量常见类型胭动脉第1分支开口距胫骨平台的距离,第1、2分支开口间距以及第1分支与主干间夹角。每个数据测量3次并求其平均值。使用SPSS17.0进行统计学分析,计数资料采用卡方检验,计量资料采用t检验或ANOVA,以P<0.05为差异具有统计学意义。结果:1)下肢CTA图像中686例患者为双侧入组,121例为单侧入组,共计入组支数为1493支。其中男性1115支,女性378支。686例患者中有624例(90.96%)左右两侧胭动脉分型相同(两侧同为Ⅰ型的为611例,89.07%;同为Ⅱ型的4例,0.58%;同为Ⅲ型的9例,1.31%),62例...
