Acute traumatic aortic rupture is a lethal injury and requires immediate diagnosis and surgical repair. The standard of diagnosis for aortic rupture is aortography. In patients in whom the angiographic findings of rupture are subtle or uncertain, intravascular ultrasound (IVUS) imaging of the descending aorta has been useful in confirming or excluding mural injury. However, because IVUS is unable to provide a complete and expeditious survey of the aorta and brachiocephalic arteries, the diagnosis of rupture will continue to rely on aortography or current generation computed tomography.
急性创伤性主动脉破裂是一种致命伤，需要立即诊断并进行手术修复。主动脉破裂的诊断标准是主动脉造影。对于破裂的血管造影结果不明显或不确定的患者，降主动脉的血管内超声（IVUS）成像有助于确认或排除壁层损伤。然而，由于IVUS无法对主动脉和头臂动脉进行完整、快速的检查，破裂的诊断仍将依赖于主动脉造影或当前一代的计算机断层扫描。
