Duplication and aneurysm of the anterior communicating artery with triplication of the anterior cerebral artery: A rare case-report
Bibliographic record
Abstract
and Importance: Anatomical variations are widely described in the anterior communicating artery (AComA) complex of the circle of Willis. Some variants may be associated with increased risk of aneurysm formation and rupture and impose a challenge for surgical interventions in treating aneurysm. Clinical Presentation: In current paper, we reported the case of a 74 years old woman who was admitted to hospital with subarachnoid hemorrhage. She was then diagnosed via preoperative computed tomography angiography to have concurrent AComA duplication and aneurysm with triplicate anterior cerebral artery. Patient underwent microsurgical clipping of the aneurysm with straight fenestrated titanium clip with good surgical and post-operative outcome. Preoperative diagnosis of these rare anatomical variations though appropriate imaging study is warranted to take optimal approach in procedure and minimize the risk of complications during or after the intervention.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
