摘 要:目的:采用16层螺旋CTA对髂-股动脉进行测量,为经髂-股动脉介入诊疗提供影像学数据。方法:收集2010年6月~9月符合要求的连续病例350例,按照年龄21~40岁、41~60岁、61~89岁分为A、B、C组。经肘正中静脉注射对比剂后,用16层螺旋CT进行包括盆腔区的增强扫描,薄层重建图像用容积再现技术对髂-股动脉进行三维重建。测量动脉分叉到髂嵴连线、股骨头上缘连线的垂直距离及动脉分叉夹角。相同性别不同年龄组间采用单因素方差分析,相同年龄组不同性别采用两独立样本t检验,不同侧别间采用配对样本t检验。结果:腹主动脉分叉、左右髂总动脉分叉、左右股总动脉分叉到股骨头上缘连线的垂直距离男性A组分别为(132.5±12.8)mm、(87.1±14.9)mm、(88.8±11.3)mm、(43.4±13.7)mm、(41.5±15.0)mm,B组为(126.5±11.6)mm、(84.8±14.2)mm、(89.1±12.9)mm、(44.3±10.1)mm、(46.2±10.1)mm,C组为(115.6±10.7)mm、(80.3±14.3)mm、(82.3±13.6)mm、(39.1±10.0)mm、(40.4±10.0)mm,女性A组分别为(135.4±12.1)mm、(91.3±15.1)mm、(97.4±14.1)mm、(36.5±10.3)mm、(36.2±10.3)mm,B组为(129.8±12.7)mm、(92.7±12.5)mm、(96.0±13.3)mm、(36.5±10.8)mm、(35.8±10.9)mm,C组为(121.2±13.1)mm、(84.0±11.3)mm、(86.3±11.4)mm、(36.4±12.2)mm、(36.9±11.0)mm。除男性左髂总动脉分叉、女性左右股总动脉分叉到股骨头上缘连线的垂直距离外,不同年龄组间差异均有统计学意义(P<0.05)。腹主动脉分叉夹角、左右髂总动脉分叉夹角男性A组分别为(38.2±5.8)°、(26.6±16.9)°、(30.5±10.8)°,B组为(38.1±11.3)°、(25.3±10.8)°、(24.8±11.2)°,C组为(45.1±16.5)°、(25.8±12.5)°、(25.6±13.2)°,女性A组分别为(46.9±10.9)°、(28.2±13.5)°、(28.9±10.2)°,B组为(40.7±11.2)°、(20.3±10.3)°、(21.6±9.7)°,C组为(45.1±11.2)°、(21.0±9.9)°、(27.0±12.1)°,男女腹主动脉分叉夹角、男性左右髂总动脉分叉夹角不同年龄组间差异有统计学意义(P<0.05Objective:To measure rofemoral artery using 16-slice CT angiography (CTA) to offer imaging data for inter- ventional procedure via iliofemoral artery. Methods: From June to September 2010, 350 patients achieving the standard were included. After injecting contrast materials through median cubita! veins, contrast-enhanced scans of pelvis were per- formed by 16-slice spiral CT. After thin-slice reconstruction, the images of iliofemoral arteries were reconstructed into 3D- images with the technique of volume rendering (VR). Vertical distances from artery bifurcations to inter-lilac-crest line or liner-femoral-head line and angles of artery bifurcation were measured. The differences among age groups were compared by analysis of variance using SPSS 13.0; and the differences between male and female were analyzed by independent-sam- ples t test, and the differences between left and right side were analyzed by paired-samples t test. Results: Vertical dis- tances from abdominal aortic bifurcation (AAB), left or right common iliac artery bifurcations (CIAB), left or right com- mon femoral artery bifurcations (CFAB) to inter-femoral-head line of male were (132.5±12.8) ram, (87.1±14.9) ram, (88.8±11.3) ram, (43.4±13.7) mm, (41.5±15.0) mm in group A; and (126.5±11.6) ram, (84.8±14.2) mm, (89.1±12.9) ram, (44.3±10.1) ram, (46.2±10.1) mm in group B; and (115.6±10.7) mm, (80.3±14.3) mm, (82.3±13.6) ram, (39.1±10.0) mm, (40.4±10.0) mm in group C.
