Abstract
In this study an unusual combination of arterial, venous and neural variations discovered
during dissection of cervical, axillary and brachial area of a cadaver is described.
Variations are thoroughly described and literature is briefly reviewed. Lateral cord
of brachial plexus was not formed; Eight Cervical root divided into anterior and posterior
division before uniting with First Thoracic root and Upper Trunk was unusually short.
Axillary artery gave origin to a superficial brachial artery and then continued as
deep brachial artery. Multiple variations in typical axillary artery branches were
present including existence of inferior pectoral artery. Cephalic vein was absent.
A variety of interventions, from relative simple as central venous catheter placement
to most complicated as brachial plexus injury repair demand thorough knowledge of
area’s regional anatomy. Familiarity with anatomic variations allows more precise
and careful interventions. Research on these variations is valuable for anatomists
and embryologists but also for clinicians because it may provide useful information
for non - typical cases but also helps in raising a high level of suspicion.
