摘要
目的:探讨电子束CT(EBCT)对钝性创伤性胸主动脉损伤(ATAI)的诊断价值。方法:采用美国Imatron C-150型EBCT扫描机对11例胸部钝性创伤患者行连续容积增强扫描。结果:11例ATAI,升主动脉破裂1例,假性动脉瘤6例,主动脉夹层3例,主动脉壁内血肿1例。EBCT不仅能清晰显示ATAI的各种征象,还能同时显示其他的胸部外伤性征象:皮下气肿、肋骨骨折、气胸、胸腔积液等。结论:ATAI表现各具特征,EBCT可明确诊断,是极适用于胸部急症的快速、无创的检查方法。
Abstract
Objective: To evaluate the diagnostic value of electron beam computed tomography(EBCT) in acute thoracic aortic injuries(ATAI). Methods: Contrast-enhanced EBCT was carried out by Imatron C-150 system. Eleven patients with blunt chest trauma were scanned by EBCT with continuous volume scanning. Results: Eleven cases including 1 ascending aorta rupture, 6 aortic pseudoaneurysms, 3 aortic dissections and 1 aortic intramural hematoma were analyzed retrospectively. EBCT not only clearly showed imaging signs of ATAI, but also showed other thoracic injuries: subcutaneous emphysema, fractures of ribs, pneumothorax, pleural effusion and so on. Conclusion: EBCT is a fast and noninvasive diagnostic tool for thoracic emergency, and could show imaging features of ATAI.
