Abstract:
Persistent trigeminal artery is an embryonic remnant of the anastomotic channel linking the internal
carotid artery and the basilar artery. Cases of vertebrobasilar insufficiency caused by the persistent
trigeminal artery with internal carotid artery stenosis has been described previously, but vertebrobasilar
insufficiency entirely due to in situ stenosis of the persistent trigeminal artery has not been reported.
A 71-year-old man presented with frequent dizzy episodes. The brain MRI showed no parenchymal
lesions. MR angiography showed poor visualization of vertebrobasilar system. He was diagnosed as
having vertebrobasilar insufficiency. Cerebral angiography revealed that there was complete occlusion
at the vertebrobasilar junction, and the basilar artery was supplied by the persistent trigeminal artery
which had severe stenosis at its origin. There was no stenosis of the internal carotid artery of both
sides. We believe that this is the first report of vertebrobasilar insufficiency due to stenosed persistent
trigeminal artery, without internal carotid artery stenosis.
