What are Subcarinal nodes?

Subcarinal lymph nodes are commonly involved by metastases from cancers of both the right and left lungs. No data exist on the relative accuracy of radiologic methods for evaluating subcarinal nodes.

What does N2 disease mean?

The true prevalence of mediastinal lymph node metastases (N2 disease) in resected pathologic T1 (pT1) NSCLC must be known to define the role of invasive mediastinal staging in these patients.

Can enlarged mediastinal lymph nodes be benign?

Introduction: Mediastinal lymphadenopathy (ML), may be caused either by malignant or benign diseases. It usually is diagnosed by chest computed tomography and bronchoscopy with endobronchial ultrasound guided TBNA (EBUS-TBNA).

What causes enlarged lymph nodes in thoracic area?

The main causes of enlargement of the lymph nodes in the chest are: A bacterial illness including tuberculosis. Cancer, such as leukemia, Hodgkin’s disease, and non-Hodgkin’s lymphoma. Lung cancer.

Where is the Subcarinal area?

The subcarinal space has been loosely defined as a region of the mediastinurn just below the tracheal carina.

Where is the Subcarinal lymph node located?

Station 7 (Subcarinal): Subcarinal nodes lie directly below the carina and between the mainstem bronchi.

What is normal size of Subcarinal lymph node?

The majority of CT studies record the short-axis diameter of a lymph node, as this is the most reproducible measurement (,3). Low paratracheal and subcarinal nodes can measure up to 11 mm in short-axis diameter. Nodes in the superior mediastinum and high paratracheal space are generally smaller and measure up to 7 mm.

Can Subcarinal lymph nodes be removed?

Systematic lymph node dissection was required to ensure the standard extent and integrity of not fewer than 3 stations of station N1 and 3 stations of station N2, including subcarinal lymph nodes; the lymph nodes were completely removed with the surrounding adipose tissue in each group (10-12).

How fast do cancerous lymph nodes grow?

If the lymph node is cancerous, the rapidity with which the lump arises and grows depends on the type of lymphoma that is present. In rapidly growing lymphomas, lumps can appear in a matter of days or weeks; in slower-growing types, it can take months or even years.

What is the most common complication of mediastinoscopy?

The most frequent complications are surgical-related: hemorrhage, recurrent palsy, pneumothorax, tracheal laceration, esophageal lesions, wound dehiscence or anesthesiology-related such as: cardiac arrest and respiratory hypoxia, various arrhythmias, cerebral insufficiency, amaurosis fugax.
