主动脉壁血肿的CT诊断

CT Diagnostic Application of Aortic Mural Hematoma

目的探讨双源CT对主动脉壁血肿的诊断应用价值。方法收集25例主动脉壁血肿患者双源CT的检查数据资料,进行多平面重组、曲面重组,最大密度投影、容积再现等处理,观察图像,分析结果。结果根据DeBaKey分型检出Ⅰ型9例,Ⅱ型2例,Ⅲ型14例;其中9例患者管壁内膜钙化斑向腔内移位,10例患者管壁检出小龛影,5例合并心包积液,1例检出胸腔积液。结论双源CT凭借其快速、无创、准确、安全的检查方法,可明确诊断主动脉壁血肿的位置、范围及其他并发征象,对临床诊断、制定下一步治疗方案有重要意义。

Objective To explore the diagnostic value of dual-source CT in aortic mural hematoma. Methods Data of dual-source CT examination of 25 patients with aortic mural hematoma were collected for multi-planar recombination, curved surface recombination, maximum density projection, volume reappearance, etc., images were observed and results were analyzed. Results According to the DeBaKey typing, there were 9 cases of type Ⅰ, 2 cases of type Ⅱ, 14 cases of type Ⅲ;among those those patients, 9 of them had the calcified plaques on their mural tubes that displaced toward inner cavities, 10 of them had small niches, which were detected on their mural tubes, 5 cases of concomitant pericardial effusion, and 1 case of pleural effusion. Conclusion dual-source CT can clearly diagnose the location, scope and other complicated signs of aortic mural hematoma rely on its rapid, noninvasive, accurate and safe examination method, which is of great significance to clinical diagnosis and the formulation of the next treatment plan.
