A study was undertaken to determine the accuracy of nasogastric tube (NGT) displacement to the right as a sign of acute traumatic rupture of the thoracic aorta (ATRTA). In 14 patients with confirmed ATRTA, the sensitivity of NGT displacement to the right was 70% using measurement of displacement from the midline on chest radiography. Two control groups, comprising victims of vehicular trauma and patients with no recent history of trauma, showed significant percentages of false positive findings for ATRTA based on NGT displacement. The presence of this radiographic sign is highly suspicious for this lethal injury; however, the absence of displacement cannot be used to exclude the diagnosis of ATRTA.
进行了一项研究，以确定鼻胃管（NGT）向右移位作为胸主动脉急性创伤性破裂（ATRTA）体征的准确性。在14例确诊为ATRTA的患者中，通过胸部X线片测量从中线的移位情况，NGT向右移位的敏感性为70%。两个对照组，包括车辆创伤受害者和近期无创伤史的患者，基于NGT移位显示出ATRTA的假阳性结果百分比很高。这种影像学征象的出现高度怀疑这种致命损伤；然而，移位的缺失不能用于排除ATRTA的诊断。
