Table 1 Classification of vertical position of catheter tip

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

Class Position of catheter tip
1 Intermediate position between the carotid bifurcation and LA origin (bifurcation between the ECA and LA)
2 LA origin (bifurcation between the ECA and LA)
3 Intermediate position between the LA origin and FA origin (bifurcation between the ECA and FA)
4 Catheter insertion into the LA (superselective intra-arterial catheterization)
  1. ECA external carotid artery, FA facial artery, LA lingual artery
