OBJECTIVE
The objective of this study was to evaluate the reproducibility of three-dimensional (3D) images of the aortic arch reconstructed using a novel image processing algorithm for non-enhanced computed tomography (CT) images of the cervicothorax and abdomen obtained before emergency endovascular surgery.
CASE PRESENTATIONS
In all, 46 patients who underwent acute mechanical thrombectomy between January and December 2018 were examined. The anatomical variations of the aortic arch were reproduced in all cases; however, the reproduction of the carotid arteries was difficult.
CONCLUSION
Our novel 3D analysis system enables obtaining information on the aortic arch easily from plain CT data that may be useful in acute endovascular treatment.
目的
本研究的目的是评估使用一种新型图像处理算法重建的主动脉弓三维（3D）图像的可重复性，该算法用于对急诊血管内手术前获得的颈胸和腹部非增强计算机断层扫描（CT）图像进行处理。
病例介绍
总共对2018年1月至12月期间接受急性机械血栓切除术的46例患者进行了检查。所有病例均再现了主动脉弓的解剖变异；然而，颈动脉的再现较为困难。
结论
我们的新型3D分析系统能够从普通CT数据中轻松获取有关主动脉弓的信息，这可能对急性血管内治疗有用。
