【摘要】：目的初步评价多层螺旋CT血管成像对肋间后动脉的解剖学显示价值,为外科手术与介入治疗提供相关解剖学信息。方法回顾性分析108例因怀疑胸部占位性病变或纵隔大血管病变行胸部双期增强扫描患者(除外累及肋间后动脉的患者)的肋间后动脉影像学资料。记录每对肋间后动脉的显示情况、起点方位、管径大小、走行及共干情况,并对其进行统计学分析。结果肋间后动脉血管成像共显示肋间后动脉1831支,总显示率为94.19%。左侧肋间后动脉的显示率为93.62%(910/972),右侧肋间后动脉显示率为94.75%(921/972)。13例(12.04%)为相邻2支肋间后动脉共干,与右侧支气管动脉共干的肋间后动脉共有58例(53.70%)。左侧肋间后动脉大部分起自胸主动脉的后壁(约6点位置);右侧肋间后动脉大部分起自胸主动脉的后壁、右后壁和右壁(约8点及9点位置),并且由上而下自胸主动脉的右壁向胸主动脉的后壁移行。两侧肋间后动脉由上而下,逐渐增粗,两两比较差异具有统计学意义(P0.05),其中以第11肋间后动脉的外径最粗。结论 256层螺旋CT血管成像可以清晰显示肋间后动脉解剖学特征,为临床提供重要信息。
[Abstract]:Objective to evaluate the anatomy of the posterior intercostal artery by multislice spiral CT angiography, and to provide anatomical information for surgery and interventional therapy. Methods the imaging data of 108 patients with suspected chest occupying lesions or mediastinal macrovascular diseases who underwent chest double phase enhanced scan (including those involving posterior intercostal artery) were retrospectively analyzed. The display of the posterior intercostal artery, the location of the starting point, the size of the diameter of the tube, the walk and the common dry condition were recorded and the statistical analysis of the posterior intercostal artery was made. Results the posterior intercostal artery angiography showed a total of 1831 posterior intercostal arteries, with a total display rate of 94.19%. The display rate of the left posterior intercostal artery was 93.62% (910/972), and the right posterior intercostal artery was 94.75% (921/972). In 13 cases (12.04%), there were 2 adjacent posterior intercostal arteries and 58 cases (53.70%) of the posterior intercostal artery that CO operated with the right bronchial artery. Most of the left intercostal artery originated from the posterior wall of the thoracic aorta (about 6 points), and the right intercostal posterior artery mostly originated from the posterior wall, right posterior wall and right wall of the thoracic aorta (about 8 and 9 points), and moved from the upper and lower part of the thoracic aorta to the posterior wall of the thoracic aorta. The posterior intercostal arteries were increased gradually from the upper intercostal arteries to 22, and the difference was statistically significant (P0.05). The outer diameter of the posterior intercostal artery was the coarsest. Conclusion 256 slice spiral CT angiography can clearly display the anatomical characteristics of the posterior intercostal artery and provide important information for the clinical.
