Thoracic outlet syndrome is a debilitating condition, impairing the function of the upper limb, and can be considered an entrapment of neurovascular structures dedicated to the upper limb. Its open treatment uses a large approach, and to date, only the structures under the clavicle have been endoscopically approached. The purpose of this Technical Note is to describe an endoscopic brachial plexus decompression at all possible entrapment areas between the neck and the arm.
