2023年7月24日 · Station 7 (Subcarinal): Subcarinal nodes lie directly below the carina and between the mainstem bronchi. To differentiate them from the paraesophageal LNs that are found more caudal, the distal aspect of the bronchus intermedius and origin of the left lower lobe bronchus is used to demarcate the right and left inferior extensions of station 7.

The following nodal stations can be biopsied by cervical mediastinoscopy: the left and right upper paratracheal nodes (station 2L and 2R), left and right lower paratracheal nodes (station 4L and 4R) and the subcarinal nodes (station 7).

2020年3月19日 · Subcarinal nodes are located in the subcarinal space, between the main bronchi ( Fig. 4.4B–D ), and drain the inferior hila and both lower lobes. They communicate in turn with the right paratracheal chain. Peribronchial nodes surround the main bronchi on …

The upper border of station 7 is the carina of the trachea. The lower border of station 7 is the upper border of the lower lobe bronchus on the left and the lower border of the bronchus intermedius on the right. IASLC lymph node map - https://www.iaslc.

2024年6月19日 · Thoracic lymph nodes are divided into 14 stations as defined by the International Association for the Study of Lung Cancer (IASLC) 1, principally in the context of oncologic staging. For the purpose of prognostication, the stations may be grouped into seven zones.

2023年7月21日 · The upper lobes typically drain to the superior tracheobronchial nodes, while the inferior lobes drain to the subcarinal nodes, located inferior to the carina, or bifurcation of the trachea.

NCI urges users to consult with a qualified physician for diagnosis and for answers to their personal medical questions. Along scalenus muscles in the base of the neck.

2021年11月28日 · At approximately 30 cm the subcarinal area is easily recognized by finding the left atrium, a large hypoechoic structure with cardiac motion, and pulling back until it disappears on the left edge of the screen.

Subcarinal nodes are located in the subcarinal space, between the main bronchi (see Fig. 4‐4B to D), and drain the inferior hila and both lower lobes. They communicate in turn with the right paratracheal chain.

2016年7月10日 · Very large lymph nodes (short axis >2 cm) in the middle mediastinum, including the subcarinal region, often reflect metastatic primary lung carcinoma, metastatic extrapulmonary carcinoma, † lymphoma, tuberculosis, fungal disease (e.g., histoplasmosis, coccidioidomycosis), or …
