正常胸片纵隔两侧边缘清楚锐利,病理情况下它可以变得模糊。究其原因,一部分是由于肺部病变所致,如肺炎、胸水、纤维粘连等。它们虽使胸片正位纵隔边缘模糊,但正常的纵隔解剖结构没有变化。当肺叶切除后,纵隔的移位和旋转是造成纵隔边缘模糊的主要原因。 作者收集近期资料完整的肺叶切除术后8例胸片作回顾性分析,观察纵隔边缘X线表现,并讨论其变化与纵隔解剖学变化的关系。 病例1:男64岁,右上叶中央型肺癌作右上叶切除术后第3天、7天分别摄全胸片后前立位片,见纵隔中线右移约2.5cm,右上纵隔边缘模糊不清,左侧纵隔边缘清楚锐利(图1)。
The edges of the mediastinum on both sides of the chest are clear and sharp, and under pathological conditions it can become blurred. The reason, in part, is due to lung lesions, such as pneumonia, pleural effusion, fibrous adhesions and so on. Although they make the chest anterior mediastinal edge fuzzy, but the normal mediastinal anatomy did not change. After lobectomy, the mediastinal shift and rotation are the main causes of blurred mediastinal edges. The authors collected recent data complete lobectomy eight cases of chest radiography for retrospective analysis of mediastinal edge X-ray findings and discuss the relationship between changes and mediastinal anatomy changes. Case 1: Male 64 years old, right upper lobe central lung cancer for right upper lobe resection after the first 3 days, 7 days were taken full chest radiograph after a vertical sheet, see right mediastinal midline shifted about 2.5cm, the right upper mediastinal margin blurred , The edge of the left mediastinum clearly sharp (Figure 1).
