We, thus, aimed at patterning unilateral and bilateral possibilities of SCA origin. Materials and Methods: In total, 205 archived records of computed tomography and magnetic resonance angiograms were used. There were defined types of SCA origin from the basilar artery (BA): \u201c0\u201d\u2014absent SCA, \u201c1\u201d\u2014preterminal, \u201c2\u201d\u2014collateral SCA, with SCA appearing as a terminal branch of BA, and \u201c3\u201d\u2014SCA from the posterior cerebral artery (PCA) of the cerebral type. Fenestrations and duplications of SCA were recorded. Bilateral combinations of types were recorded as follows: A (1 + 0), B (1 + 1), C (1 + 2), D (1 + 3), E (1 + duplicated SCA), F (2 + 2), G (2 + 3), H (3 + 3), I (3 + duplicated SCA), J (1 + fenestrated SCA). Results: Type 0 SCAs were found in 0.25%, type 1 in 71.29%, type 2 in 19.06%, and type 3 in 9.41%. Absent and fenestrated SCAs were each found in a single case. The most frequent combinations were B (58.05%), C (13.17%) and F (13.17%). Bilateral symmetrical types occurred in 70.7% of cases. Fetal types of PCA and the artery of Percheron modified the BA ends. Combinations of C, F, and G changed the BA ends or tips; thus, different subtypes resulted in five BA bifurcation patterns, including five BA trifurcations and one BA quadrifurcation. BA trifurcation was also found in cases with duplicated SCAs. Conclusions: The SCA has various anatomical possibilities of origin and bilateral combinations that are not presented in anatomical lectures. Details on the specific end of the BA should be gathered on a case-by-case basis.<\/jats:p>","DOI":"10.3390\/medicina59122164","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T12:00:37Z","timestamp":1702468837000},"page":"2164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["An Update on the Superior Cerebellar Artery Origin Type"],"prefix":"10.3390","volume":"59","author":[{"given":"Ana-Maria","family":"Davidoiu","sequence":"first","affiliation":[{"name":"Doctoral School, Faculty of Medicine, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy, RO-300041 Timi\u0219oara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihai","family":"Laz\u0103r","sequence":"additional","affiliation":[{"name":"Department 2, Division of Physiopathology II, Faculty of Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra Diana","family":"Vrapciu","sequence":"additional","affiliation":[{"name":"Department 1, Division of Anatomy, Faculty of Dentistry, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petrinel Mugurel","family":"R\u0103doi","sequence":"additional","affiliation":[{"name":"Department 6\u2013Clinical Neurosciences, Division of Neurosurgery, Faculty of Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"},{"name":"Clinic of Neurosurgery, \u201cDr. Bagdasar-Arseni\u201d Emergency Clinical Hospital, RO-041915 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corneliu","family":"Toader","sequence":"additional","affiliation":[{"name":"Department 6\u2013Clinical Neurosciences, Division of Neurosurgery, Faculty of Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"},{"name":"Clinic of Neurosurgery, \u201cDr. Bagdasar-Arseni\u201d Emergency Clinical Hospital, RO-041915 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8723-0540","authenticated-orcid":false,"given":"Mugurel Constantin","family":"Rusu","sequence":"additional","affiliation":[{"name":"Department 1, Division of Anatomy, Faculty of Dentistry, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,13]]},"reference":[{"key":"ref_1","unstructured":"Feneis, H., and Dauber, W.
