Remove or not, that is the question: A case report on carotid artery cannulation during indwelling venous hemodialysis catheter
Bibliographic record
Abstract
A 58-year-old woman visited the emergency department for acute occlusion of arteriovenous fistula. One session of hemodialysis was scheduled via temporary venous hemodialysis catheter before thrombectomy. Unfortunately, neck arterial cannulation was discovered after complete placement of catheter. The catheter was removed immediately but bleeding could not be stopped. Pseudoaneurysm over the right carotid artery was proved by angiography and repaired by graft stent. Arterial cannulation during venous hemodialysis catheter insertion is a rare but serious complication and there is no standard response recommended. Immediate removal of the misplaced hemodialysis catheter might not be the best choice. We suggest to leave the misplaced catheter in artery until further intervention in consideration of complications and repair access. Every hemodialysis center should standardize responses to arterial cannulation during venous hemodialysis catheter indwelling, especially carotid puncture happens, according to the medical facility.

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.
