hinteres Mediastinum
The posterior mediastinum (or paravertebral compartment) is a potential space along the paravertebral sulci. It is conceptually considered a portion of the inferior mediastinum, and separated from the middle mediastinal compartment and the remainder of the extrapleural intrathoracic cavity by arbitrary lines.
Gross anatomy
Relations
- superiorly: superior mediastinum
- anteriorly: anterior and middle mediastinum (which form the other compartments of the inferior mediastinum).
It is continuous with the retropharyngeal space via the posterior part of the superior mediastinum.
