Table 2 Classification of horizontal position of catheter tip

From: Computational fluid dynamics study of intra-arterial chemotherapy for oral cancer

Class Position of catheter tip
C Center of the ECA
F Forward shift of catheter tip toward the target artery from center of the ECA
B Backward shift of catheter tip toward the target artery from center of the ECA
L Left shift of catheter tip toward the target artery from center of the ECA
R Right shift of catheter tip toward the target artery from center of the ECA
  1. Target arteries are the lingual, facial, and occipital arteries. 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
