摘要
目的探讨多层螺旋CT诊断肺撕裂伤的价值。资料与方法对67例外伤患者均使用螺旋CT进行胸部平扫,螺距0.9,扫描模式6×0.75 mm,重组层厚、层距0.75 mm。结果CT特征表现为肺气囊肿、气液囊肿、血肿。其中气囊肿58个,多为薄壁。气液囊肿23个,壁厚薄不均,囊内积液少量。56个气囊肿、气液囊肿边界模糊,边界清楚25个。肺血肿球形血肿14例,直径20～50 mm,边界清楚。气囊肿、气液囊肿或血肿周围常有不同程度肺挫伤,表现为云絮状、斑片状模糊影。41例有肋骨骨折,38例液气胸,12例气胸,6例少量胸腔积液,5例纵隔气肿,49例胸壁皮下气肿,21例胸椎骨折,15例椎旁血肿;49例同时有颅内血肿、腹部脏器损伤。结论多层螺旋CT能准确、迅速诊断肺撕裂伤的部位、范围、类型,以及合并征象,对临床治疗具有重要指导作用。
Objective To explore the value of multislice spiral CT （MSCT） in diagnosis lung lacerated wound. Materials and Methods 67 patients with thorax trauma performed MSCT With the pitch of 0.9 and 0.75 mm thickness. Resuits CT findings included pulmonary air-filled cysts with thin walls in 58 cases, fluid and air-filled cysts with irregular walls in 23 cases, hematomas with diameters of 20 -50ram in 14 cases, rib bone fractures in 41 cases, pneumothorax in 38 cases, hydropneumothorax in 42 cases, subcutaneous emphysema in 49 cases, mediastinal emphysema in 5 cases. 49 cases simultaneously had craniocerebral or abdomen trauma. The pulmonary contusions were frequently occurred showed as patchy opaque arounding cysts and hematomas. Conclusion Muhislice spiral CT imagings which can show the location, extent, degree, type and complications of lung lacerated wound clearly play the important role to guide therapy.
