Persistent carotid-vertebrobasilar anastomoses
Updates to Article Attributes
Body
was changed:
The persistent carotid-vertebrobasilar anastomoses are named (with, with the exception of the proatlantal artery), using the cranial nerves with which they run:
-
persistent trigeminal artery
- arises from proximal cavernousICA
- most common persistent carotid-vertebrobasilar anastomosis
- two types - lateral and medial
- Saltzman classification
- type I - absent ipsilateral posterior communicating artery
- type II - fetal origin of ipsilateral posterior communicating artery
-
persistent otic (acoustic) artery
- controversial, perhaps non-existent
- arises from petrous ICA
- rare, as it is the first anastomosis to regress
-
persistent hypoglossal artery
- arises from cervical ICA at C1 to C3 levels
-
persistent proatlantal artery
- type I arises from internal carotid artery
- type II arises from external carotid artery
