Surgical removal of an embolized intravenous catheter fragment from the axillobrachial vein of a dog.
Bibliographic record
Abstract
An 8-month-old neutered male miniature Australian shepherd was examined for evaluation and treatment of suspected embolization of a peripheral intravenous catheter fragment. Embolism had occurred after the catheter cannula was accidentally cut during removal from the right cephalic vein. Radiographs showed migration of the fragment to the proximolateral right brachium. Surgical exploration, assisted by fluoroscopy, localized the fragment to the axillobrachial vein, where the tip was visualized within the vessel lodged against the wall. A venotomy was performed, allowing the fragment to be extracted from the peripheral vessel before it could migrate farther. The dog recovered from surgery without complication and was discharged the following day. Key clinical message: In the case reported here, the axillobrachial vein was a clinically important location on the migration path of a cephalic intravenous catheter embolus. Fluoroscopy allowed for quick localization of an embolized intravenous catheter fragment within a peripheral vein and directed open surgical retrieval of the foreign body. A peripheral catheter fragment can be retrieved surgically from a vein in a limb even when a tourniquet has not been applied immediately.

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.
