Dissection of thorax from a posterior approach
Ligamentous attachment of mediastinal structures to vertebral column
The upper part of the specimen shown in 131-7 is presented in a close-up view with the anterior longitudinal ligament (14) retracted to the right to expose a heavy, ligamentous band which extends down to the aorta from the level of the third and fourth thoracic vertebral bodies. The vertebral attachments of this band blend with the anterior longitudinal ligament near the midline. Inferiorly the ligament blends with the adventitia of the posterior part of the aortic arch and the upper thoracic aorta. It can also be traced forward to where it blends with fascia of the esophagus and trachea, although this arrangement is not visible in this view. This suspensory structure is shown elsewhere in the dissection of another specimen (128-1).
