“…Agenesis of the AICA is an anatomical expression reported in a significant number of specimens both in our work (16.1%) and in previous studies; for the AICA a figure of 2-36.1% has been reported [1,5,15,16,17]. The agenesis of the PICA observed in the present study (7.5%) is slightly lower than what has been reported in other population groups, within a range of 9.6-38.4% [1,5,15,16,17,20]. The variations of the cerebellar irrigation related to arterial origins, agenesis, duplication, calibers, distribution of irrigated territories, have been reported previously [1,16] in 65.2-88.3%.…”

Aim: The aim of this investigation was characterize morphologically the cerebellar artery and its branches in a specimen of autopsy material. Methods:This descriptive cross-sectional study evaluated the anatomical characteristics of the cerebellar arteries and their branches in 93 brain stem and cerebellum blocks obtained from fresh cadavers. The specimens were perfused bilaterally channeling the proximal segments of the internal carotid and vertebral arteries with a semi-synthetic resin (Palatal GP40L 85%; styrene 15%) impregnated with mineral red dye. We evaluated the distribution patterns of the cerebellar artery and its branches. Results:The calibers of the superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA) were 1.46 ± 0.2 mm, 1.02 ± 0.35 mm and 1.45 ± 0.37 mm, respectively. Agenesis of the SCA was observed in six specimens (3.2%), AICA in 30 (16.1%), and PICA in 14 (7.5%) specimens. Usual irrigation was observed in 44 (47.3%) cerebellar blocks, whereas 49 (52.7%) specimens showed irrigation variants, 23 (46.9%) of which appeared bilaterally. The dominant distribution of the cerebellar arteries corresponded to SCA in 9 (12.5%) cases, AICA in 46 (63.9%) and PICA in 7 (9.7%) specimens; shared dominance was found in 10 (13.9%) specimens. Conclusion:The high variability of the cerebellar arteries observed in the present study is consistent with previous reports. The diverse anatomic expressions of the cerebellar arteries were typified in relation to their dominance and territories irrigated, useful for the diagnosis and clinical-surgical management of the cerebellum blood supply.

“…[3][4][5][6] However, with 2D angiography, fenestrations are rarely found: In 2 studies of 5190 and 4500 cerebral angiograms, fenestrations were reported in 0.7% and 0.07%, respectively. 1,7 Apparently, with 2D imaging, most fenestrations are overlooked or are invisible because of over- projecting vessels, preferential flow in 1 limb, or location remote from the region of interest.…”

“…Surgical and anatomic studies indicate that fenestrations of intracranial arteries occur commonly, especially in the anterior communicating artery (AcomA) complex. [3][4][5][6] Demonstration of fenestrations on conventional angiography is exceptional. Most fenestrations are only visible from 1 specific viewing angle, which is likely not present in the limited available projections of conventional angiography.…”

BACKGROUND AND PURPOSE:Fenestrations of intracranial arteries are variants resulting from incomplete fusion of primitive vessels. An association with aneurysms is suggested in many studies. On conventional angiography, fenestrations are rarely visible. 3D rotational angiography (3DRA) provides improved visualization of cerebral vessels from any desired angle. We used 3DRA to assess the frequency and location of fenestrations of intracranial arteries and a possible relationship with aneurysms.

“…In large autopsy series the incidence of basilar fenestrations was between 1.3% and 6% (Wollschlaeger et al 1967;Hoffman and Wilson 1979), a discrepancy to the rate of 0.02% to 0.6% in angiographic series (Takahashi et al 1973;Teal et al 1973;Sanders et al 1993). Very thin and angiographically occult dividers, and often a view obscured by the aneurysm, may explain the difference between autopsy and angiographical series.…”
