The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle.[1][2][3] It is surrounded by the axillary fat.[1][2] It is an extension of the prevertebral fascia of the deep cervical fascia[citation needed] and is continuous with the carotid sheath at the venous angle.[4]
