The importance of the LV topography is related to skull base neurosurgical approaches. Based on the hypothesis of the existence of as yet unidentified anatomical possibilities of the LV, we aimed through this research to document the superficial venous topographic patterns at the lateral and inferior surfaces of the temporal lobe. (2) Methods: A retrospective cohort of 50 computed tomography angiograms (CTAs) of 32 males and 18 females was documented. (3) Results: Absent (type 0) LVs were found in 6% of cases. Anterior (temporal, squamosal\u2013petrosal\u2013mastoid, type 1) LVs were found in 12% of cases. LVs with a posterior, temporoparietal course (type 2) were found to be bilateral in 46% of cases and unilateral in 36% of cases. Type 3 LVs (posterior, parietooccipital) were found to be bilateral in 8% and unilateral in 32% of cases. In 24% of cases, duplicate LVs were found that were either complete or incomplete. A quadruplicate LV was found in a male case. On 78 sides, the LV drained either into a tentorial sinus or into the TS. (4) Conclusions: The anatomy of the vein of Labb\u00e9 is variable in terms of its course, the number of veins and the modality of drainage; thus, it should determine personalized neurosurgical and interventional approaches. A new classification of the anatomical variations of Labb\u00e9\u2019s vein, as detected on the CTAs, is proposed here (types 0\u20133).<\/jats:p>","DOI":"10.3390\/tomography8050183","type":"journal-article","created":{"date-parts":[[2022,8,31]],"date-time":"2022-08-31T02:09:36Z","timestamp":1661911776000},"page":"2182-2192","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A New Classification of the Anatomical Variations of Labb\u00e9\u2019s Inferior Anastomotic Vein"],"prefix":"10.3390","volume":"8","author":[{"given":"Drago\u015f Ionu\u0163","family":"Minc\u0103","sequence":"first","affiliation":[{"name":"Division of Anatomy, Department 1, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 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":"Division of Anatomy, Department 1, Faculty of Dental Medicine, \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":"Division of Neurosurgery, Department 6\u2014Clinical Neurosciences, 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\/0000-0003-4130-9402","authenticated-orcid":false,"given":"Sorin","family":"Hostiuc","sequence":"additional","affiliation":[{"name":"Department of Legal Medicine and Bioethics, Faculty of Dental Medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, RO-020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corneliu","family":"Toader","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department 6\u2014Clinical Neurosciences, 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"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1007\/s00276-011-0782-1","article-title":"Microsurgical anatomy of the vein of Labbe","volume":"33","author":"Avci","year":"2011","journal-title":"Surg.
