目的 :探讨X线和CT对胸部创伤的诊断价值和特征。材料和方法 :回顾性分析 69例胸部创伤X线平片及CT表现。结果 :肺挫伤 43例 ,肺不张及肺萎陷 2 1例 ,骨折合并气胸 2 4例 ,胸腔积血 3 5例 ,皮下气肿和纵隔气肿 2 1例 ,其它合并损伤 :颅脑挫伤 13例 ,肝破裂 2例 ,脾破裂 2例 ,胸椎骨折 4例 ,锁骨骨折 3例 ,肩胛骨骨折 2例。结论 :CT能明确创伤病变的部位、性质、程度 ,敏感性和特异性高 ,能清晰显示X线平片难以发现的少量胸腔积液和积气 ,对危重及复合伤患者可减少搬动 ,并能较快完成检查 ,是胸部创伤最重要的检查方法之一。

X-Ray and CT Diagnosis of Chest Trauma

Purpose: To evaluated the diagnostic value of CT in thoracic trauma. Materials and Methods: CT and X ray films data of 69 cases of thoracic trauma were retrospectively reviewed and analyzed, The appearance of X ray films were compared to that of CT. Results: The CT scans showed that contusion of the lung was in 43 cases, atelectasis and collaps of lung 21. Complications included fracture complicated pneumothorax in 24 cases, hemothorax 35, subcutaneous and mediastinal emphysema 21, hepatorrexis 2, splenic rupture 2, thoracic vertebral fracture 4, clavicular fracture 3, fracture of scapula 2 and ribs fracture 22. Conclusion: CT can correctly make the diagnosis of position, character and degree of traumatic lesions, CT has high sensitively and specificity for the patients with dangerous and complicated trauma, CT scan can be rapidly performed and patients may be removed little, therefore, it is the most reliable method for the diagnosing of traumatic chest.
