title: Trifurcation of the Left Common Carotid Artery.
abstract: BACKGROUND
  Trifurcation of the common carotid artery is an unusual variation.
  
  
  METHODS
  We report a case of left common carotid artery trifurcation in a 74-year-old man. The left common carotid artery divided into the internal carotid, external carotid and facial arteries. Herein, the anatomy of the carotid arteries and the Doppler sonography and CT angiography findings of the left common carotid artery trifurcation were described with images.
  
  
  CONCLUSIONS
  The variations of the carotid arteries should be known to avoid and reduce the complications during the invasive procedures.
