Variation of brachial artery,median nerve and axillary nerve of unilateral upper limb:a case report
The anatomical variation of the blood vessels and brachial plexus of the upper limb is very complicated.In general population,the brachial artery divides into the radial artery and ulnar artery in cubital fossa.The median nerve consists of lateral and medial roots,and the axillary nerve divides into anterior and posterior branches after passing through the quadrangular space.Although variations in the vascular or neural pattern of the upper limb in humans are fairly common,it is very rare to see complex neurovascular variations in one limb.The present study reports complicated variation of unilateral upper limb,which aims at emphasizing the rare formation of brachial plexus and vessel.
