8 17 : 386 Abstract Variant type of persistent primitive trigeminal Report of a case and assessment of reported cases Tomoichiro Kimura, M. D. and Takashi Ueda, M. D. Department of Neurosurgery, Kojima Central Hospital Department of Neurosurgery, Social Insurance Miyazaki Konan Hospital We experienced a case of a variant type of persistent primitive trigeminal (PTAV). An anomalous branch of the precavernous internal carotid is very rarely demonstrated angiographically. Its branch, originating at the level where the persistent primitive trigeminal is usually found but having no communication with the basilar, supplies vessels of the posterior fossa directly. Its location and course approcimated those of the supperior cerebellar. We report onecase and review 75 reported cases. Based on a detailed assessment of these 76 cases, we emphasize the clinical significance of PTAV as follows: 1) it is readily be accompanied by cerebrovascular disease; and 2) it may be complicated with deficits of the cranial nerves including trigeminal neuralgia. The embryological mechanism and incidence of the are also discussed. (Jpn J Stroke 17: , 1995)
