During development, longitudinal arteries are formed, connected with the ICAs by temporary (or primitive) trigeminal, otic, stapedial and hypoglossal arteries (see Padget DH 1948 The development of the cranial arteries in the human embryo. Contrib Embryol Carnegie Instn 32:2-5-261). These 'Primitive arteries' may persist (Wohlschlaeger G, Wohlschlaeger PB 1964 The primitive trigeminal artery as seen angiographically and at postmortem examination. AJR Am J Roentgenol 92:761-768; Suttner N, Mura J, Tedeschi H, et al. 2000 Persistent trigeminal artery: A unique anatomic specimen - analysis and therapeutic implications. Neurosurgery 47:428-434).
