摘要: 摘要 目的   初步探讨256层螺旋CT(MSCT)血管成像对胸廓内动脉的显示价值。方法    回顾性分析107例临床怀疑胸腹主动脉病变患者的血管造影图像,原始增强图像结合最大密度投影(MIP)、容积再现(VR)等后处理重组图像,观察两侧胸廓内动脉的走行规律及其解剖分支,将两侧胸廓内动脉沿走行平均分为近、中、远3段,测量三个节段血管腔内径、两侧胸廓内动脉长度及其分支肌膈动脉内径,分别测量两侧胸廓内动脉与邻近胸骨缘的距离。结果   107例患者两侧胸廓内动脉及其分支肌膈动脉显示率均为100%,肋间前动脉显示率为89.3%,所选病例胸廓内动脉均起自于两侧锁骨下动脉,向下沿肋软骨内侧面迂曲走行逐渐变细,至第6肋间隙水平分为腹壁上动脉和肌膈动脉,两侧胸廓内动脉近端血管管腔分别为左侧(2.52±0.38)mm,右侧(2.49±0.27)mm,中段左侧(2.32±0.19)mm,右侧(2.30±0.22)mm,远段左侧(2.02±0.17)mm,右侧(2.13±0.12)mm,同侧两两比较差异有统计学意义(p<0.05),两侧相应节段两两比较差异无统计学意义(p>0.05)。左侧胸廓内动脉较右侧稍长,左胸廓内动脉平均长度为(22.33±2.10)cm,右侧胸廓内动脉平均长度为(20.96±1.99)cm,两侧比较差异有统计学意义(p<0.05)。两侧肌膈动脉平均内径:右侧为(1.91±0.22)mm,左侧为(1.89±0.11)mm,两侧比较差异无统计学意义(p>0.05)。两侧胸廓内动脉至胸骨边缘距离:左侧为(2.13±0.17)cm,右侧为(2.07±0.26)cm,两侧比较差异无统计学意义(p>0.05)。结论   应用256层螺旋CT血管成像可以清晰显示正常胸廓内动脉走行规律及其解剖特征,为临床相关疾病的诊断治疗提供了较为重要信息。关键词 胸廓内动脉;体层摄影术,X线计算机;血管造影术

Abstract: Abstract  Objective   To study the value of 256 slice spiral CT in internal thoracic artery. Methods   retrospectively analysis the angiographic images of 107 patients who were suspected of thoracic and abdominal aortic disease, through observed the original image and maximum intensity projection ( MIP ) image and volume rendering ( VR ) image, preliminary observed the internal thoracic artery running rule and its branch on both sides, each side of the internal thoracic artery were divided into 3 sections, then measured lumen and vessel length and its branches of three segmental vascular of the internal thoracic artery, measured the lumen of diaphragmatic artery diameter, measured the distance between internal thoracic artery and each border of sternum. Results  107 cases of patients with both sides of the internal thoracic artery and its branches diaphragmatic arteries can be shown, all of the selected cases of internal thoracic artery have arisen from both sides of the subclavian artery, downward along the inner side of costal cartilage, to the level of the sixth intercostal space were divided into superior epigastric artery and diaphragmatic arteries, two side intrathoracic artery proximal to the vascular lumen diameter , left were ( 2.52± 0.38 ) mm, right were ( 2.49 ±0.27) mm, the middle section , left were ( 2.32 ±0.19) mm, right were ( 2.30 ±0.22) mm, the distal left were ( 2.02± 0.17 ) mm, right were ( 2.13 ±0.12) mm, between the three department there were statistics significance ( p<0.05 ), between each side of the corresponding segment there were not statistical significance ( p>0.05 ). The length of left internal thoracic artery average was ( 22.33± 2.10 ) cm, the right internal thoracic artery average was ( 20.96± 1.99 ) cm, there were significant difference ( p<0.05 ). Two sides of the diameter of diaphragmatic arteries: the right were (1.91 ±0.22) mm, left were ( 1.89 ±0.11) mm, there were not significant difference ( p>0.05 ). On both sides the distance of the internal thoracic artery to the sternal edge: left were ( 2.13± 0.17 ) cm, right were ( 2.07 ±0.26),there were not significant difference ( p>0.05 ). Conclusion   the application of 256 slice spiral CT angiography can clearly show the internal thoracic artery running rule and anatomical features, clinical diagnosis and treatment for diseases related to provide a relatively important information.
