The anatomy of the thoracic outlet is complex. However, if you learn the anatomy of the thoracic outlet, you can understand thoracic outlet syndrome. Doctors have described many variants of the muscles and soft tissues in the thoracic outlet. If these variants compress or stretch the brachial plexus, symptoms occur. In addition, movement of the arms can cause spaces in each thoracic outlet to narrow. When these changes bring the rib and clavicle close enough to each other, they may compress or stretch the brachial plexus. Thus, patients may suffer symptoms in certain arm positions.

When you learn how all these structures interact, thoracic outlet syndrome becomes easier to understand. We aim to provide full and detailed pictures of the anatomy of the thoracic outlet. In addition, we present interactive graphic models to help patients and their providers learn this vital information. The NeoVista® website has been built and designed to help patients and doctors learn this complex anatomy.
