Retrieval of refluxed Onyx cast during a paediatric AVM embolisation
Bibliographic record
Abstract
Endovascular embolisation of arteriovenous malformations (AVM) has been greatly facilitated by liquid embolic agents. While advancements in catheter technology and techniques of creating a proximal plug minimise the risk of inadvertent proximal reflux of the embolysate, this remains one of the main complications associated with use of liquid embolics.We report a case of paediatric AVM embolisation which was complicated by parent vessel occlusion due to inadvertent proximal reflux of the embolysate in pericallosal artery. This was safely and effectively rescued using a stent retriever manoeuvre, following similar principles and tenets as in endovascular thrombectomy in stroke. This is the first case report of using a newer smaller 3 mm stentriever in a paediatric medium vessel occlusion, although for a different aetiology but with the same goal.Bail-out or rescue strategy as presented here is an important addition to neurointerventionalists' armamentarium to salvage a non-targeted migration of liquid embolic agent.

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.
