Percutaneous transcatheter embolisation of active haemorrhage following radiofrequency ablation of hepatocellular carcinoma
Bibliographic record
Abstract
A 72-year-old woman with hepatitis C virus cirrhosis underwent a surveillance ultrasound examination which identified a new hepatic lesion. A workup triphasic CT examination demonstrated a 3.7 cm lesion at the hepatic dome with arterial enhancement and portal venous washout consistent with hepatocellular carcinoma. She subsequently proceeded for treatment with radiofrequency ablation (RFA). RFA was technically successful, but the patient became hypotensive and tachycardic postprocedure. A CT angiogram demonstrated active arterial intraperitoneal haemorrhage from the RFA site. The patient returned to the interventional suite for catheter angiography which confirmed the presence of active haemorrhage from the hepatic arterial branch supplying segment VIII. The bleeding vessel was selectively catheterised with a microcatheter, and successfully embolised with 250-355 µm polyvinyl alcohol particles.

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.
