Differences in Aortic Diameter Measurements With Intravascular Ultrasound and Computed Tomography After Blunt Traumatic Aortic Injury

血管内超声在主动脉直径测量中的差异和闭合性创伤性主动脉损伤后的计算机断层扫描

Objective:
目的：
Intravascular ultrasound (IVUS) has been recommended as an adjunct to thoracic endovascular aortic repair (TEVAR) because computed tomography (CT) in injured patients with vasoconstriction due to shock may inaccurately determine the true aortic diameter. Hypothesis: CT underestimates aortic diameter in trauma patients compared with IVUS.
血管内超声（IVUS）已被推荐为胸主动脉腔内修复术的辅助方法（TEVAR）因为计算机断层扫描（CT）在受伤的患者由于休克血管收缩可能不准确确定真正的主动脉直径。假设：CT对主动脉直径在创伤患者血管内超声的比较。

Methods:
方法:
Patients treated by TEVAR for blunt aortic injury from June 2013 to 2016 were reviewed. Cases in which IVUS was not used and those without complete CT and IVUS images were excluded. Threedimensional reconstructions were used to derive centerline diameters of the aorta proximal and distal to the injury. IVUS diameters were taken from adventitial measurements of the aorta. Measurements were made by an investigator blinded to the graft implanted. Descriptive statistics were used to compare patients with concordant diameter (group 1) to patients with discordant diameters (group 2).
回顾性分析2013年6月～2016胸主动脉损伤患者行胸主动脉腔内修复术的患者的治疗。案件中，不使用血管内超声和那些没有完整的CT和血管内超声图像的情况下被排除在外。三维重建得到的主动脉近端和远端的损伤中心线直径。血管内超声直径取主动脉外膜的测量。测量是由一个研究者对移植植入的蒙蔽。使用描述性统计患者进行比较一致的直径（1组）患者不同直径（2组）。
