急性肺撕裂伤的CT表现及其诊断价值

目的:探讨急性肺撕裂伤的CT表现及其诊断价值。材料与方法:20例急性肺撕裂伤患者,均于伤后1-10小时行CT检查,其中17例在10小时内行X线检查。结果:20例急性肺撕裂伤中,17例发生在中下肺叶,仅3例发生在两肺上叶,绝大多数位于肺的边缘部位及脊柱旁。单发4例,单侧多发14例,双侧多发2例。其中肺气囊肿18个,多为薄壁;肺气液囊肿43个,壁厚薄不均匀,囊内积液多为少量,内壁光滑,多个小囊聚集5例,大囊周边多个小囊聚集3例;楔形含气裂隙3例,长80-95mm,裂口外侧达肺表面胸膜下,内侧达肺野内带脊柱旁;肺内血肿3个,呈类圆形高密度影。合并肺挫伤17例,肋骨骨折12例,液气胸8例,气胸3例,头胸腹部等多发伤8例。结论:肺气囊肿、肺气液囊肿是急性肺撕裂伤特征性CT表现,肺楔形含气裂隙是本病特有的征像,CT是明确急性肺撕裂伤诊断及其严重程度的最敏感、最特异性的影像检查方法。

CT Manifestations and Diagnosis Value of Acute Lung Lacerated Wound

Purpose：To explore the CT manifestationgs and diagnosis value in acute lung lacerated wound.Materials and Methods：Twenty patients of acute lung lacerated wound were examined by CT within 1-10h after injury,among seventeen patients were examined by X-ray within 10h.Results：Of twenty patients,acute lung lacerated wound involved the suffer-lower lung lobe in 17 cases and the upper lung lobe in 3 cases,among which 4 cases involved the lung lobe with 1 lesion,14 cases in the singular side lung with multilesion,2 cases in the both sides lung with multilesion.CT imaging findings included lung air-filled cysts with thin walls in 18 cases,fluid and air-filled cysts with irregular walls in 43 cases,wedged and air-filled cranny with breachs of 80-95mm in 3 cases,hematomas with roundness in 3 cases.The cases simultaneously had lung contuse in 17cases,rib bone fractures in 12 cases,pneumothorax in 8 cases,hydropneumothorax in 3 cases,craniocerebral or abdomen trauma in 8 cases.Conclusion：Lung air-filled cysts or fluid and air-filled cysts is the characteristic CT imaging finding of acute lung lacerated wound,wedged and air-filled cranny is the specialties imaging,CT is the best susceptible and the best special imaging wise of clear diagnosis and trauma grade about acute lung lacerated wound.
