title: Unilateral anomalous antebrachial vasculature--a clinico-embryological insight.
abstract: OBJECTIVE
  An important and frequently reported arterial variant of the upper extremity is the superficial ulnar artery (SUA). Although SUA is not an uncommon variation, its presence should be detected timely as any surgical procedure in this region could put this unnaturally present superficial vessel to risk. Therefore, we sought to report this anomaly relating to the brachial arterial branching pattern.
  
  
  METHODS
  Through the course of a usual instructive gross anatomy class an arterial variant of the brachial artery was noted. A scrupulous dissection was carried out and the specimen photographed.
  
  
  RESULTS
  The present study reports the unilateral presence of abnormal branching pattern and disposition of antebrachial blood vessels. The brachial artery is seen to branch off into superficial ulnar artery (SUA) and usual radial artery. Interestingly, common interosseous artery (CIA) springs from the radial artery instead of the ulnar artery which is the usual case.
  
  
  CONCLUSIONS
  Simple procedures such as venepuncture and intra arterial injections may become cumbersome and complication prone. The study is a humble attempt to caution the radiologists before interpreting angiographic films and the surgeons before performing reconstructions in this region.
