  • Amgad S. Hanna


From a posterior approach, the brachial plexus is anterior to the following muscle planes from superficial to deep: trapezius, rhomboids and levator scapulae, serratus posterior superior, scalenus posterior, and scalenus medius respectively. In this exposure, the subclavian artery is anterior to (deep to) the lower trunk.
