                  For the Arteria carotis interna (Internal carotid artery or ICA, the subdivision into C1-C4 segments (Gibo et al. 1981 J Neurosurg 55:560-574) is replaced by the more recent Bouthillier subdivision into C1-C7 (Bouthillier A, van Loveren HR, Keller JT 1996 Segments of the internal carotid artery: A new classification. Neurosurgery 38:425-433). Main differences are: - the Pars lacera (Segmentum C3) is a short segment that begins above the Foramen lacerum and ends at the Ligamentum petrolinguale. The new Segments C2 and C3 cover the old Segment C2; - the Pars cavernosa is the new Segmentum C4; - the Segments C5-C7 comprise the Pars cerebralis (C4) of the Gibo/TA subdivision: the Pars clinoidea (Segmentum C5) is a borderline segment extending between dural rings, by definition never intradural, often surrounded by a venous collar (a protrusion of the Cavernous sinus), the Pars ophthalmica is Segmentum C6, and the Pars communicans Segmentum C7.
