High division and variation in brachial artery branching pattern.

Abstract

In a 45 year male cadaver unusual variation of right brachial artery branching was observed. Brachial artery also showed high division in to radial and ulnar artery in upper third of arm. The posterior circumflex humeral artery, profunda brachii artery and superior ulnar collateral artery all arose from one common trunk in proximal part of brachial artery before its termination. In this report we endeavor to discuss the relevance of embryogenesis and clinical importance.
