Retrieval of a firmly impacted knotted coronary catheter through the contralateral femoral artery using a balloon angioplasty catheter
Bibliographic record
Abstract
Knotting of a coronary catheter during cardiac catheterization is a relatively common event and can usually be resolved by simply untwisting the catheter or by straightening it with a guidewire. If these manoeuvres fail, the knotted catheter may be retrieved using a snare device; however, if unsuccessful, surgical extraction may prove necessary. The authors describe a case in which a snare device failed to retrieve a knotted catheter firmly impacted within a loop in the external iliac artery. The catheter was successfully mobilized using an angioplasty balloon inflated distal to the site of impaction then pulled back, allowing dislodgement of the knot and subsequent extraction of the catheter from the contralateral femoral artery.

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.
