Cadaveric analysis reveals bilateral variations in upper limb arteries, indicating anatomical diversity.

This work aims to document unusual variations in upper limb arterial anatomy, focusing on the profunda brachii and associated anastomoses.
Dissection of a male cadaver's upper limb arteries to observe variations.
Comparison of arterial branches on the right and left sides.
Focus on double profunda brachii and cubital anastomoses.
Identification of anatomical relationships and anomalies.
Bilateral double profunda brachii arteries were noted, with variations in the origins on each side.
An unusual transverse anastomosis between ulnar and brachioradial arteries was present on the left side.
No communication was found in the right cubital fossa between the brachioradial and ulnar arteries.
Absence of the radial recurrent artery and other notable differences in arterial branching were documented.
