title: Median arcuate ligament syndrome.
abstract: OBJECTIVE
  To describe the importance of obtaining erect views when evaluating the celiac artery with sonography.
  
  
  METHODS
  Two patients had duplex and color flow Doppler sonographic evaluations of the celiac artery, including inspiration, expiration, and erect views.
  
  
  RESULTS
  Both patients had elevated celiac artery velocities with inspiration and expiration. These results alone would suggest celiac artery stenosis. With erect views, the celiac artery velocities returned to normal. The addition of erect views allowed the correct diagnosis of median arcuate ligament syndrome to be made.
  
  
  CONCLUSIONS
  When evaluating the celiac artery, it is important to include erect views to prevent misdiagnosis of celiac artery stenosis.
