【摘要】：目的初步评价256层螺旋CT血管造影术对胸廓内动脉的解剖学显示价值。方法回顾性分析107例拟诊胸主动脉病变患者的血管造影图像,观察两侧胸廓内动脉的走行规律及其解剖分支特征,沿胸骨角及第6肋间隙水平分为近、中、远3段,测量3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和至邻近胸骨缘的距离,并进行统计学分析。结果 107例患者两侧胸廓内动脉显示率均为100%。两侧胸廓内动脉中,同侧近、中、远各段内径比较差异有统计学意义(P0.05),两侧相应节段比较差异无统计学意义(P0.05),不同性别各段内径间比较差异无统计学意义(P0.05)。左侧胸廓内动脉较右侧稍长(P0.05),男性胸廓内动脉较女性长(P0.05)。两侧肌膈动脉内径比较差异无统计学意义(P0.05),不同性别间内径比较差异无统计学意义(P0.05)。至胸骨边缘距离,两侧比较差异无统计学意义(P0.05),不同性别间距离比较差异无统计学意义(P0.05)。两侧胸廓内动脉末端分支,右侧两支分支者89例(83.18%)、三支者10例(9.35%)、四支者8例(7.48%)。左侧两支分支者91例(85.05%)、三支者9例(8.41%)、四支者7例(6.54%),两侧均以两支分支型最多见。结论采用256层螺旋CT血管造影术可以清晰观察胸廓内动脉走行规律及其解剖分支特征,可为临床提供较为重要的解剖信息,对术前评估有一定临床意义。
[Abstract]:Objective to evaluate the anatomical value of 256-slice spiral CT angiography in displaying the internal thoracic artery. Methods Angiographic images of 107 patients with suspected thoracic aortic lesions were retrospectively analyzed. The patterns of internal thoracic arteries and their anatomical branches were observed. According to the level of the angle of sternum and the sixth intercostal space, they were divided into three segments: proximal, middle and distal. The internal diameter of three segmental vessels, the length of bilateral internal thoracic arteries, the internal diameter of the branches of the phrenic artery and the distance to the border of the sternum were measured, and the statistical analysis was carried out. Results the display rate of bilateral internal thoracic arteries was 100% in 107 patients. There were significant differences in the internal diameter of bilateral internal thoracic arteries (P0.05) in the same side proximal middle and distal segments (P0.05). There was no significant difference in the internal diameters of the corresponding segments between the two sides (P0.05) and there was no significant difference in the internal diameters of different gender segments (P0.05). The left internal thoracic artery was a little longer than the right (P0.05), and the male was longer than the female (P0.05). There was no significant difference in the diameters of bilateral phrenic arteries (P0.05), but there was no significant difference in the internal diameters between the sexes (P0.05). There was no significant difference between the two sides (P0.05) and no significant difference between the two sexes (P0.05) from the margin of sternum to the margin of sternum (P0.05). There were 89 cases (83.18%) with two branches on the right side, 10 cases (9.35%) with three branches and 8 cases (7.48%) with four branches. There were 91 cases (85.05%) with two branches on the left, 9 cases (8.41%) with three branches and 7 cases (6.54%) with four branches. Conclusion 256-slice spiral CT angiography can clearly observe the pattern of internal thoracic artery and its anatomic branch characteristics, which can provide important anatomical information for clinical practice and has certain clinical significance for preoperative evaluation.
