Abstract: The Information of an amorphic brachial artery branching patterns and incidence will be important for clinicians and surgeons when performing invasive procedures in arm and forearm. In this study ten cadaveric specimens were dissected, all were with an average age of 50-55 years out of which two cadavers showed high bifurcation of brachial artery seven was normal and one showed abnormal variations which is rare and not yet reported. The Branching pattern observed was the right brachial artery gave a branch just opposite to the origin of superior ulnar collateral and there was no inferior ulnar collateral so these arteries are named as medial and lateral ulnar collateral instead of later. Then just 1cm above the cubital fossa ulnar artery was observed which coursed superficially in the forearm as superficial ulnar artery. On the left side double brachial artery and which got joined by vasa aberrantia was found. This cadaveric survey may give awareness to anesthetists to prevent intra-arterial cannulation, drug administration and for orthopaedicians while operating the elbow injury. The abnormal anastomosis around elbow joint will be useful for microsurgeons.
