急性肺挫伤的螺旋CT诊断及临床价值

Acute pulmonary contusion of spiral CT diagnosis and its clinical value

目的探讨急性肺挫伤的螺旋CT诊断及其临床应用价值。方法回顾性分析38例急性肺挫伤的CT表现及临床资料。结果实质型28例,表现为单侧或双侧肺实质内沿支气管走行分布的斑片状边缘模糊密度增高影。间质型5例,表现为肺纹理不均匀性增粗、边缘模糊。磨玻璃型5例,表现为一侧或双侧局部肺野透亮度减低、其内见正常走行肺纹理的磨玻璃样影。本组中合并肺撕裂伤伴肺内血肿3例。伴其他部位不同程度损伤16例。结论胸部螺旋CT平扫对肺挫伤诊断准确率高,能实时明确创伤的部位、性质、程度和范围,并能对临床治疗、转归和预后判断起到很好的指导作用,应作为急诊危重及复合伤患者首选的影像检查方法。

Objective To investigate acute pulmonary contusion of spiral CT diagnosis and clinical application value. Methods retrospective analysis of 38 cases of acute pulmonary contusion CT findings and clinical data. Results 28 cases with solid type, showed uni- lateral or bilateral lung parenchyma along the bronchial walking distribution of patchy fuzzy edge density increased. Interstitial type in 5 ca- ses, for the performance of lung texture inhomogeneity thickening, edge blur. Ground glass type in 5 cases, showed unilateral or bilateral partial lung field penetrating brightness, which reduce the normal running of lung texture of ground glass opacity. The group combined with puhnonary laceration with intrapulmonary hematoma in 3 cases. With other parts of the different degree of injury in 16 cases. Conclusion thoracic spiral CT scan in pulmonary contusion with high diagnostic accuracy, real - time definitive trauma site, nature, extent and range, and to the clinical treatment, outcome and prognostic play a very good role in guiding, should serve as a critical and complex trauma patients preferred imaging method.
