Stent retriever for Tandem Acute Revascularization Technique (START): a novel technique for the endovascular management of tandem occlusions
Bibliographic record
Abstract
Tandem occlusions, characterized by the simultaneous presence of an intracranial large vessel occlusion and extracranial carotid artery stenosis or occlusion,1 pose a unique endovascular challenge.2 3 Typically, the extracranial occlusion is a result of atherosclerotic plaque; however, dissections are also a possible cause. It is currently uncertain whether an intracranial first approach or an extracranial first approach should be employed.4 5 A new technique has been developed which allows for the simultaneous treatment of both the intracranial and the extracranial lesion.6 We describe a variation of this technique: the stent retriever for tandem acute revascularization technique (START), which consists of simultaneously treating the intracranial lesion with stent retriever and contact aspiration, and the extracranial lesion with balloon angioplasty. We present a technical video explaining all the steps of START.(video 1) neurintsurg;16/5/529/V1F1V1Video 1Description and example of the START.

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.
