Variations in anatomy of basal vein of Rosenthal: a systematic review
Bibliographic record
Abstract
BACKGROUND: The basal vein of Rosenthal (BVR) is a venous structure in the deep cerebral venous system. It plays an important role in cerebral haemorrhages, particularly subarachnoid haemorrhages and perimesencephalic haemorrhages. The aim of this study was to evaluate the BVR's anatomical and functional classification and its role in various clinical situations. AIM OF THE STUDY: The review was conducted from its inception up to 27 September, 2024. It was made according to the PRISMA Statement 2020 and using the following databases: Scopus, Pubmed and Web of Science. Studies were considered eligible if they provided precise data and information on the anatomical variation of the basal vein of Rosenthal. The quality assessment was assessed using the Newcastle-Ottawa Quality Assessment Scale. MATERIALS AND METHODS: A total of 12 articles, the studies behind which were conducted in different countries, were included. Data on the classification of the basal vein of Rosenthal, surgical or radiological, and the outcome, mainly haemorrhagic, were reported. BVR type b or c correlates with increased venous fragility and an outcome of idiopathic haemorrhage. CONCLUSIONS: The anatomical classification of the BVR highlights the importance of careful surgical planning and prophylactic measures while providing valuable insights into idiopathic cerebral haemorrhages.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
