Bouthillier classification of internal carotid artery segments
Alain Bouthillier et al. described a seven segment internal carotid artery (ICA) classification system in 1996 . It remains the most widely used system for describing ICA segments.
A helpful mnemonic for remembering ICA segments is:

Classification
- C1: cervical segment (starts at carotid bifurcation)
- C2: petrous segment (starts at carotid canal)
- C3: lacerum segment (starts at posterior edge of foramen lacerum)
- C4: cavernous segment (starts at the superior margin of petrolingual ligament)
- C5: clinoid segment (starts at proximal dural ring / anterior clinoid process)
- C6: ophthalmic (supraclinoid) segment (starts at distal dural ring / cavernous sinus roof)
- C7: communicating (terminal) segment (starts just proximal to the origin of posterior communicating artery, ends at bifurcation into middle and anterior cerebral arteries)

There are a few other classifications systems including those proposed by Fischer (1938), Gibo (1981), and Lasjaunias (1984) .
