摘　　要：目的探讨肋间动脉用于冠状动脉旁路移植的可行性。方法收集2011年7月至2012年12月上海长海医院36例中国成人胸主动脉CTA原始横断面图像资料，利用VitreaFX图像后处理工作站，对原始图像进行容积再现（VR）、多平面重建（MPR）、曲面重建（CPR）、最大密度投影（MIP）等后处理，观察并测量第8、9、10双侧肋间动脉及双侧胸廓内动脉数据。结果CT检查示第8～10肋间动脉平均长度及对应测量点管径相仿，长度均大于180mm，腋中线水平管径均大于2．1mm，右侧肋间动脉平均长度较左侧略长，左、右肋间动脉各测量点管径相仿，相应点管径约相当于胸廓内动脉85％-90％。结论肋间动脉可作为冠状动脉旁路移植的理想后备血管。Objective To assess potential suitability of the intercostal artery as a conduit in coronary bypass graft. Methods Collected 36 cases of chinese adult thoracic aorta CTA original cross-sectional images, the images were retrospectively reconstructed under volume rendering technology （ VR）, multi-planar reconstruction （ MPR）, curved planar reformation （CPR） and maximum intensity projection（MIP）. Observed and measured the data of the 8th, 9th and 10th bilateral intercostal arteries and internal thoracic arteries. Results Toshiba 320-slice volume scanning CT can clearly display the intercostal arteries . The average length and diameter at corresponding point of the left and right 8-10th intercostal artery is similar, all the length is longer than 180 mm, and the diameter at axillary line is all bigger than 2.1 mm, the mean length of right intercostal arteries is slightly longer than the left intercostal arteries, the diameter at each corresponding point of left and right intercostal artery is similar, and equivalent to approximately 85% -90% of internal thoracic artery. Conclusion Intercostal artery can be used as an ideal alternative vessel in coronary artery bypass grafting.
