Abstract
The supply to the skull base and the brain depends on the parasellar arterial system. The parasellar region is lateral to the sella turcica and includes the cavernous region with its extradural venous plexus. In many species the branchial arteries give rise to the cerebral feeders. These arteries originate from a network of arterial channels (rete) lateral to the sella; this rete is later replaced by the intracavernous internal carotid artery or carotid siphon. The carotid-basilar anastomoses will determine, through their regression, the presence and role of these potential sources of supply to the brain. As seen in Chap. 3, the carotid-basilar arteries include the internal carotid artery but also the branches of the external carotid artery.
The venous drainage of the base of the skull, seen from above and from the side. The cavernous confluent is demonstrated with its tributaries and drainage. SOV, Superior ophthalmic vein; SSV, superficial sylvian vein; DSV, deep sylvian vein; VFO, vein of the foramen ovale; SPS, superior petrosal sinus; IPS, inferior petrosal sinus; TOS, transverse occipital sinus; VFR, vein of the foramen rotundum
