Displacement of the nasogastric tube to the right as a new sign in the diagnosis of an acute traumatic rupture of the thoracic aorta was reevaluated by statistical analysis in 28 patients (seven patients with a traumatic aortic aneurysm and 21 patients with normal aortas). This new sign was compared with the commonly used chest radiographic findings in 46 patients (eight patients with a traumatic aortic aneurysm and 38 with normal aortas). This study showed that when both the trachea and the nasogastric tube were shifted to the right, as seen on the chest radiograph, the patient had a 96% probability of having an acute rupture of the thoracic aorta.
通过对28例患者（7例创伤性主动脉瘤患者和21例主动脉正常患者）进行统计分析，重新评估了鼻胃管向右移位作为急性创伤性胸主动脉破裂诊断新体征的情况。将这一新体征与46例患者（8例创伤性主动脉瘤患者和38例主动脉正常患者）常用的胸部X线表现进行了比较。这项研究表明，胸部X线片显示气管和鼻胃管均向右移位时，患者发生急性胸主动脉破裂的概率为96%。
