Introduction: The dural venous sinuses drain the blood and cerebrospinal fluid circulating through the brain toward the internal jugular veins. The transverse sinuses are bilateral structures in the posterior portion of the skull that originate at the confluence of sinuses. Such cerebral venous structures have a complex anatomy and are marked by variations. Thus, a complete understanding of the morphology and variations of these anatomical structures is essential for clinical and surgical practice. This study summarized the literature on the anatomical organization of the transverse sinuses, variations, and potential clinical-surgical repercussions. Objective: To review the anatomy, variations, and possible clinical-surgical implications of the transverse sinuses. Methods: This integrative literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Studies published in English in the last 15 years were retrieved from PubMed, Virtual Health Library, and MEDLINE databases, based on the following descriptors: transverse sinuses, anatomy, and anatomic variation. Results: Of the 48 studies identified after duplicate removal, 10 met the eligibility criteria and were included in the synthesis. Conclusion: Hypoplasia of the left transverse sinus is the most common anatomical variation and is more frequent in adult men over 60 years old.
