Some structural factors associated with a potentially higher risk for developing CVST have been described. However, angulation of the dural venous sinuses (DVS) has yet to be studied as a structural factor. The current study was performed because this variable could be related to alterations in venous flow, thus predisposing to a greater risk of CVST development. Additionally, such information could help shed light on venous sinus stenosis (VSS) at or near the transverse\u2010sigmoid junction. The angulations formed in the different segments of the grooves of the transverse (TS), sigmoid (SS), and superior sagittal sinuses (SSS) were measured in 52 skulls (104 sides). The overall angulation of the TS groove was measured using two reference points. Other variables were examined, such as the communication pattern at the sinuses' confluence and the sinus grooves' lengths and widths. The patterns of communication between sides were compared statistically. The most typical communication pattern at the sinuses' confluence was a right\u2010dominant TS groove (82.98%). The mean angulations of the entire left TS groove at two different points (A and B) were 46\u00b0 and 43\u00b0. Those of the right TS groove were 44\u00b0 and 45\u00b0. The median angulations of the left and right SSS\u2010transverse sinus junction grooves were 127\u00b0 and 124\u00b0. The mean angulations of the left and right TS\u2010SSJsv grooves were 111\u00b0 (range 82\u00b0\u2013152\u00b0) and 103\u00b0 (range 79\u00b0\u2013130\u00b0). Differentiating normal and abnormal angulations of the DVSs of the posterior cranial fossa can help to explain why some patients are more susceptible to pathologies affecting the DVSs, such as CVST and VSS. Future application of these findings to patients with such pathologies is now necessary to extrapolate our results.<\/jats:p>","DOI":"10.1002\/ca.24154","type":"journal-article","created":{"date-parts":[[2024,3,13]],"date-time":"2024-03-13T02:25:22Z","timestamp":1710296722000},"page":"546-554","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Angulation of the dural venous sinuses of the posterior cranial fossa: Anatomical study with clinical and surgical applications"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4148-5687","authenticated-orcid":false,"given":"Juan J.","family":"Cardona","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8502-7952","authenticated-orcid":false,"given":"Joe","family":"Iwanaga","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"},{"name":"Department of Structural &amp; Cellular Biology Tulane University School of Medicine  New Orleans Louisiana USA"},{"name":"Department of Neurology Tulane University School of Medicine  New Orleans Louisiana USA"},{"name":"Department of Oral and Maxillofacial Anatomy, Graduate School of Medical and Dental Sciences Tokyo Medical and Dental University  Tokyo Japan"},{"name":"Division of Gross and Clinical Anatomy, Department of Anatomy Kurume University School of Medicine  Kurume Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4748-9021","authenticated-orcid":false,"given":"Arada","family":"Chaiyamoon","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"},{"name":"Department of Anatomy, Faculty of Medicine Khon Kaen University  Khon Kaen Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4396-2516","authenticated-orcid":false,"given":"Arthur","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9412-4252","authenticated-orcid":false,"given":"Christopher M.","family":"Nickele","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Edward\u2010Elmhurst Health  Naperville Illinois USA"},{"name":"Department of Neurosurgery University of Tennessee Health Sciences Center  Memphis Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8209-0534","authenticated-orcid":false,"given":"Matthew R.","family":"Amans","sequence":"additional","affiliation":[{"name":"Department of Radiology and Biomedical Imaging University of California San Francisco  San Francisco California USA"},{"name":"Department of Neurological Surgery University of California San Francisco  San Francisco California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1302-0655","authenticated-orcid":false,"given":"Daniel M.","family":"Heiferman","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Edward\u2010Elmhurst Health  Naperville Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6508-0202","authenticated-orcid":false,"given":"Kendrick D.","family":"Johnson","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8077-8992","authenticated-orcid":false,"given":"Aaron S.","family":"Dumont","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tulane Center for Clinical Neurosciences Tulane University School of Medicine  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1317-1047","authenticated-orcid":false,"given":"R.
