Abstract
A cerebral aneurysmal case associated with persistent trigeminal artery and occlusion of the subclavian artery is reported. The patient was a 58-year-old female who had an episode of dizziness, headache, and consciousness disturbance in 1980. Another sudden attack of dizziness and unconsciousness occurred in November, 1982. At admission her consciousness was almost clear, and she complained severe headache. Neurological findings were normal, except for nuchal rigidity. The pulse in the left radial artery was irregular and that in the right radial artery was not palpable. Cerebral angiography showed right persistent trigeminal artery and a saccular aneurysm of the right internal carotid artery at the posterior communicating branch. Right frontotemporal craniotomy and neck clipping of the aneurysm were performed. Occlusion of the right subclavian artery was demonstrated by brachiocephalic angiography.
The authors have collected reports of 33 cerebral aneurysmal cases associated with persistent trigeminal artery. No cases of cerebral aneurysm associated with both persistent trigeminal artery and occlusion of the subclavian artery were found.
