肺或纵隔疾患,如肺癌、食道癌、恶性淋巴瘤、白血病以及结核、结节病等,若伴存Botallo 管淋巴结肿大时,X 线示主动脉弓与左主支气管之间的左上纵隔胸膜反折线将出现膨隆、偏位或变形,从而有助于肺或纵隔恶性肿瘤的诊断,并预知纵隔淋巴结转移。本文对此进行综述。左上纵隔胸膜反折线与Botallo 管淋巴结的 X 线解剖Blank 根据胸部正位像,分析正常的左上纵隔胸膜反折线,从主动脉弓至左主支气管水平的连线称 A 线,共分5型:①双重曲线上凹下凸;②单曲线向外凸;③上凹下呈直线;④
Pulmonary or mediastinal disorders such as lung cancer, esophageal cancer, malignant lymphoma, leukemia, and tuberculosis, sarcoidosis, etc. If accompanied by Botallo tube lymphadenopathy, X-rays indicate the left upper mediastinal pleural antiretroviral line between the aortic arch and the left main bronchus. There will be bulging, dislocation, or deformation, which will help diagnose the lung or mediastinal malignancy and predict mediastinal lymph node metastasis. This article reviews this. X-ray anatomy of the left upper mediastinal pleura reflexion line and the Botallo tube lymph node. According to the chest anatomic image, the normal left upper mediastinal pleura antiretroflex line was analyzed. The line from the aortic arch to the left main bronchus level was called the A line and was divided into 5 types: 1 double Concave and convex on the curve; 2 single curve convex outward; 3 concave on the straight line; 4
