Approximately 25% of infarcts acute strokes occurs in brainstem and infarcts involving the posterior inferior cerebellar artery
territory may affect the trigeminal nuclei i.e.
Exposure and maneuverability score (0[degrees] and 30[degrees] endoscopes without endoscope Surgery simulation cannula) Vestibular neurectomy 2, S2 Vascular decompression 2, S2 (CN VII-AICA) Drilling of the fundus (internal 2, S2 acoustic canal) Exposure and maneuverability score (0[degrees] and 30[degrees] endoscopes with Surgery simulation endoscope cannula) Vestibular neurectomy 2, S3 Vascular decompression 2, S3 (CN VII-AICA) Drilling of the fundus (internal 2, S4 acoustic canal) AICA: anterior inferior cerebellar artery
The thin arrow in panel C identifies the left anterior inferior cerebellar artery
The vasculature is supplied by branches of three arteries: the posterior cerebral artery (PCA) and the basilar and the superior cerebellar artery
(SCA), depending on the level .
LVA--left vertebral artery, Py--pyramid, RVA--right vertebral artery, BA--basilar artery, RinCA--right inferior cerebellar artery
, and LinCA--left inferior cerebellar artery
The most common offending vessel is the superior cerebellar artery
followed by the anterior and inferior cerebellar artery
We examined the effects of initiating fluoxetine in a patient with bipolar 2 disorder following left posterior inferior cerebellar artery
Occlusion of right vertebral artery at origin with collaterals from occipital artery and occluded posterior inferior cerebellar artery
(PICA) were noted (Figures 1-3).
(a) MRA shows stenosis of BA (solid arrow) and right anterior inferior cerebellar artery
In previous studies, cases of PTA terminating in cerebellar artery
are extremely rare [2, 3].
The remaining 3 aneurysms included one at the clinoid segment of the right ICA, one at the bifurcation of the right MCA, and one at the bifurcation of the basilar artery and right superior cerebellar artery
. Clipping surgery was planned for 4 aneurysms in the left anterior circulation.
(8) demonstrated hypoperfusion of the left medial frontal area in a patient with a right superior cerebellar artery
territory infarction via SPECT analysis.
Other sequelae include downstream embolisation of a thrombus, anterior spinal artery compromise causing spinal cord ischaemia, and occlusion of blood flow to the posterior inferior cerebellar artery
(PICA), causing lateral medullary syndrome.
