Definition

The carotid siphon is a U or S-shaped part to the ICA that varies with age. It begins at the posterior bend of the cavernous part of ICA and ends at the cerebral part, at ICA bifurcation.

Note: this anatomical structure is mainly a radiological landmark so the boundaries are not well anatomically defined.
