Serial eight patients with thoracic aortic aneurysms were evaluated by a newly developed three-dimensional CT angiography (3D-CT) from December 1992 to January 1993. The patients include 3 aortic dissections, 3 aortic arch aneurysms, one descending aortic aneurysm and one thoracoabdominal aortic aneurysm. The surgical treatment was performed after the evaluation of 3D-CT, and the operative findings were compared to the three-dimensional images reconstructed by 3D-CT in all patients. Three-dimensional displays were achieved using the unique method of data collection of the helical (spiral) scanner with continuous tube rotation and continuous table feed. A intravenous contrast material was used to image the thoracic aorta and major aortic branches with the single-breath-hold technique. Two and three-dimensional images reconstructed by 3D-CT were displayed within 10-20 minutes after the scanning. These three-dimensional images of the aortic lesions could be displayed in any angle we chose. Three-dimensional structures of the thoracic aorta and major aortic branches were clearly visualized and easily recognized by 3D-CT. These images were similar to the intraoperative findings and were quite useful to determine the operative procedure. The successful repair of thoracic aortic aneurysm was achieved in all cases. 3D-CT is a new and attractive modality to assess the vascular system. Although our experience is limited, 3D-CT may be a useful and powerful diagnostic method for the surgical treatment of thoracic aortic aneurysm.
1992年12月至1993年1月期间，对连续8例胸主动脉瘤患者采用新开发的三维CT血管造影（3D-CT）进行评估。患者包括3例主动脉夹层、3例主动脉弓动脉瘤、1例降主动脉瘤和1例胸腹主动脉瘤。在3D-CT评估后进行手术治疗，并将所有患者的手术结果与3D-CT重建的三维图像进行比较。使用螺旋（螺旋）扫描仪独特的数据采集方法实现三维显示，即管连续旋转和床连续进给。采用单屏呼吸技术，使用静脉造影剂对胸主动脉和主要主动脉分支进行成像。扫描后10-20分钟内显示3D-CT重建的二维和三维图像。这些主动脉病变的三维图像可以以我们选择的任何角度显示。3D-CT能清晰显示胸主动脉和主要主动脉分支的三维结构，易于识别。这些图像与术中所见相似，对确定手术方案非常有用。所有病例均成功修复胸主动脉瘤。3D-CT是一种评估血管系统的新的有吸引力的方法。尽管我们的经验有限，但3D-CT可能是胸主动脉瘤手术治疗中一种有用且强大的诊断方法。
