The Application Value of Spiral CT in Diagnosis and Dynamic Observation of Pulmonary Laceration
-
摘要: 目的：探讨螺旋CT在肺撕裂伤的诊断及动态观察中的应用价值。方法：回顾性分析20例肺撕裂伤的CT表现。结果：20例患者共发现45个病灶，右肺25个，左肺20个。CT表现为肺气囊9个、肺气液囊12个、胸膜下气泡影15个、肺血肿7个及楔形含气裂隙2个。肺撕裂伤周围均合并不同程度的肺挫伤。45个病灶中，26个病灶位于肺表面或胸膜下，5个病灶位于肺深部，14个病灶位于脊柱旁。20例患者均伴有肋骨骨折，8例患者合并血气胸。CT动态观察，发现7个肺气囊腔内见液体进入，形成肺气液囊；胸膜下气泡影6例形成血气胸，5例出现肺血肿伴胸腔积液；1~2月肺气囊、肺气液囊及肺血肿吸收和缩小。结论：肺气囊、肺气液囊及胸膜下气泡影是肺撕裂伤特征性CT表现，肺楔形含气裂隙是该病特有的CT征象。CT检查是早期发现、诊断和动态观察肺撕裂伤最有效的影像检查方法。Abstract: Objective: To investigate the application value of spiral CT in the diagnosis and dynamic observation of pulmonary laceration. Methods: CT results of twenty patients with pulmorary laceration were retrospectively analyzed. Results: A total of 45 lesions were found in the 20 patients, with 25 on the right side and 20 on the left side. CT manifestations were pneumatocele (n=9), pulmonary liquid-air cavity (n=12), sub-pleural gas-bubble shadow (n=15), intrapulmonary hematoma (n=7) and wedge shaped gas fissures (n=2). Various degrees of lung contusion around the pulmonary laceration could be observed in all patients. The locations of the 45 lesions of laceration included lung surface or sub-pleural region (n=26), deep site of lung (n=5) and paravertebral area (n=14). Rib fracture was detected in all patients and hemopneumothorax was found in 8 patients. The results of CT dynamic observation are as follows:liquid was seen and pulmonary liquid-air cavities were formed in 7 lung cavities, 6 sub-pleural gas-bubble shadow formed into hemopneumothorax, while 5 patients were diagnosed as pulmonary hematoma with pleural effusion. Besides, pneumatocele, pulmonary liquid-air cavity and absorption and shrinkage of pulmonary hematoma were found in one or two months. Conclusion: The characteristic manifestations of pulmonary laceration are pneumatocele, pulmonary liquid-air cavity and sub-pleural gas-bubble shadow, while the wedge shaped gas fissures is a specific sign of the disease. Spiral CT examination plays the most effective role in early detection and diagnosis and dynamic observation of the pulmonary laceration.
