Abstract

Anatomy & Morphology Life Sciences & Biomedicine Radiology, Nuclear Medicine & Medical Imaging Science & Technology Surgery
The median nerve maintains a close relationship with the brachial artery in the upper limb. Variability in the formation and distribution of upper extremity vessels is frequently encountered during donor body dissections or surgical procedures. This case presents a rare anatomical variation of the brachial artery emerging through an opening in the median nerve. The median nerve formed a small opening without the contribution from additional nerve roots and the remaining vasculature of the upper limb was otherwise normal. An abnormal arrangement of a neurovascular bundle in the arm can cause sensory and motor issues, as well as vascular implications. This variation has clinical significance in surgical interventions and potentially daily functioning. To our knowledge, this is the first report of a small median nerve opening pierced by the brachial artery.
