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 supraorbital keyhole approach effectively exposes the frontal lobe base, anterior clinoid process, canalis opticus, olfactory sulcus, olfactory tract, optic nerve, optic chiasm, oculomotor nerve, anterior communicating artery, anterior cerebral artery A1 segment, pituitary stalk, diaphragma sellae, dorsum sellae, posterior clinoid process, basilar artery apex, posterior cerebral artery P1 segment, superior cerebellar artery
proximal, front upper pontine and interpeduncular cistern, anteromedial temporal lobe, internal carotid, middle cerebral artery (M1, M2 segment, and part of M3 segment), anterior choroidal artery, posterior communicating artery; and contralateral carotid artery medial surface, anterior cerebral artery A1 and A2 proximal, middle cerebral artery M1 and M2 proximal.
The tumor was not amenable to en bloc resection due to involvement of the internal carotid artery and the anterior inferior cerebellar artery
12) have shown that there was a high incidence of IEL defects in the extradural portion and near the origin of Posterior Inferior Cerebellar Artery
(PICA), showing that there was thinning of the intima in the areas of IEL defects, whereas Park et al.
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
In previous studies, cases of PTA terminating in cerebellar artery
are extremely rare [2, 3].
8) demonstrated hypoperfusion of the left medial frontal area in a patient with a right superior cerebellar artery
territory infarction via SPECT analysis.
In the posterior circulation, the giant aneurysms involve the basilar artery apex, followed by vertebrobasilar junction, peripheral segments of the posterior cerebral artery (PCA), posterior inferior cerebellar artery
(PICA), and the trunk of basilar artery (3,6,7,8,9,10,11).
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.
like CN III, it passes between the posterior cerebral artery and superior cerebellar artery
There was no history of fever but patient gave history of right CVA secondary to right posterior inferior cerebellar artery
territory infarct two years ago with some residual weakness of the left upper extremity.
Three years ago, when he reported to a neurosurgery emergency department due to profound headache; he had been diagnosed as having posterior inferior cerebellar artery
arteriovenous malformation based on Magnetic Resonance Imaging (MRI) findings.
