Superolateral boundary of axillary dissection is: (A) Clavipectoral fascia, (B) Branchial plexus, (C) Axillary aery, (D) Axillary vein
Answer is D. Lateral group of axillary nodes are present along axillary vein. Axillary dissection is the removal of fat, fascia, nodes in the axilla. Usually level 1 and level 2 nodes are removed. Nodes below the axillary vein are usually removed. so the superolateral boundary of axillary dissection is axillary vein. Dissection is done through an individual crease transverse inciaion in the axilla. Reference :SRB's Manual of Surgery, 6th Edition, page no = 543, 529.
