VESSEL ARTERY DISSECTION AND PSEUDOANEURYSMS: ENDOVASCULAR APPROACHES
Bibliographic record
Abstract
Intracranial dissections are frequently recognized as a cause of stroke and subarachnoid hemorrhage. The posterior circulation is the most common location for these dissections. The purpose of this article is to focus on the presentation and management of vertebral artery and posterior cerebral artery dissections. For patients presenting with stroke anticoagulation is the first line of treatment. For those presenting with a bleed proximal occlusion using endovascular techniques is the treatment of choice. Vertebral artery dissections (VADs) can be treated with either balloons or coils, and early angiographic follow-up is needed to reassess the status of the diseased segment. Trapping by endovascular techniques may be needed in a limited number of these VADs. Posterior cerebral artery dissections presenting with a bleed are best treated using Guglielmi detachable coils to achieve the shortest segment of occlusion.

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.
