Classification of horizontal position of catheter tip. Target arteries are the lingual, facial, and occipital arteries. The catheter tip rotates centering on a point 10 mm away from the tip, and the amount of shift from the centerline of the catheter is a quarter of the diameter of the external carotid artery (ECA). Classification of horizontal position of catheter tip is determined in distal view of the ECA. LA lingual artery
