Fig 4 - Brachial plexus paralysis after thoracoscopic esophagectomy for esophageal cancer in the prone position: A thought-provoking case report of an unexpected complication

Fig. 4. Eden's test. Eden's test for the costoclavicular syndrome form of thoracic outlet syndrome. The patient is asked to push the chest out and pull the shoulders back as if standing at military attention, while the therapist palpates the strength of the radial pulse. Pushing the chest out brings the first rib forward, while pulling the shoulder girdles back brings the clavicle back, thereby decreasing the space between them. A positive finding is a weakening of the strength of the radial pulse, indicating compression of the subclavian artery in the costoclavicular space. It can be assumed that if the subclavian artery is being compressed, the brachial plexus is also being compressed.
