Fig. 1 The division of the ICA in three segments: segment 1, the bicarotid region; segment 2, the retrostyloid region. The dashed oblique line (corresponding to the Blaisdell line between the tip of the mastoid process and the angle of the jaw) separates segment 1 from segment 2; and segment 3, the infratemporal fossa before penetration into the base of the skull.

Fig. 4 A, An angiogram of a traumatic aneurysm located at the base of the skull in a 24-year-old man. B, CT scan with three-dimensional reconstruction. The lateral reconstruction shows the aneurysm (arrows ), where the artery penetrates into the carotid canal. C, Follow-up angiogram after reconstruction. Venous graft was performed through an infratemporal approach.
