Saltzman type Termination site Pcom I Basilar artery between the SCA Hypoplasia and the AICA II Basilar artery above the origin of Patent the SCA IIIa Directly the SCA Patent Illb Directly the AICA Patent IIIc Directly the PICA Patent Pcom, posterior communicating artery; SCA, superior cerebellar artery
; AICA, anterior inferior cerebellar artery
; and PICA, posterior inferior cerebellar artery
A causative vessel was found on the root exit zone of all the patients, 3 had anterior inferior cerebellar artery
and 1 had basilar artery.
Gross (mesoscopic) and applied anatomy of the anterior inferior cerebellar artery
in man with special reference to its course through the cerebellopontine angle region.
Less commonly, it is caused by occlusion of the posterior inferior cerebellar artery
Of this group, 4 had cortical atrophy, 3 had an acoustic neuroma, 1 had an anteroinferior cerebellar artery vascular loop, 1 had a Chiari malformation, and the remaining 7 had changes consistent with small-vessel ischemic disease.
One patient had an anteroinferior cerebellar artery vascular loop, 1 had carotid stenosis, and 1 had small-vessel changes.
Continues its route and it issues about three or four pontine arteries in the pons, and in the emergence of the trigeminus nerve it issues the medium cerebellar artery.
Getty mentions that the swine rostral cerebellar artery is the caudal communicant artery branch, and according to observations of this study regarding the boar basilar artery, we can state that the basilar artery is formed from the anastomosis of the vertebral arteries, which issues several branch, where the main ones are the medium cerebellar arteries.
A loop of the superior cerebellar artery
(SCA) and occasionally the anterior inferior cerebellar artery
(AICA) or the petrosal vein is identified as the vessel causing the compression.
The intracranial portion of the facial nerve is supplied by the anterior inferior cerebellar artery
12] The posterior inferior cerebellar artery supplies blood to the medulla and the cerebellum.
7] The anterior inferior cerebellar artery is responsible for supplying blood to parts of the cerebellum and pons.
