Acute traumatic aortic injury (ATAI) is a life-threatening injury. CT is the imaging tool of choice, and the knowledge of direct and indirect signs of injury, grading system, and current management protocol helps the emergency radiologist to better identify and classify the injury and provide additional details that can impact management options. Newer dual-source CT technology with ultrafast acquisition speed has also influenced the appropriate protocol for imaging in patients with suspected ATAI. This review highlights the imaging protocol in patients with blunt trauma, CT appearance and grading systems of ATAI, management options, and the role of the multidisciplinary team in the management of these patients. We also briefly review the current literature on the definition, treatment, and follow-up protocol in patients with minimal aortic injury.
急性创伤性主动脉损伤(ATAI)是一种危及生命的损伤。CT是首选的成像工具,了解损伤的直接和间接征象、分级系统以及当前的管理方案有助于急诊放射科医生更好地识别和分类损伤,并提供可能影响管理选择的额外细节。具有超快采集速度的新型双源CT技术也影响了疑似ATAI患者的合适成像方案。本综述重点介绍了钝性创伤患者的成像方案、ATAI的CT表现和分级系统、管理选择以及多学科团队在这些患者管理中的作用。我们还简要回顾了当前关于轻度主动脉损伤患者的定义、治疗和随访方案的文献。
