Abstract
Gibson C, John P, Amaral J. A novel approach to endovascular treatment of severe hepatic vein stenoses following liver transplant in children. Pediatr Transplantation 2012. © 2012 John Wiley & Sons A/S. Abstract: Hepatic vein stenoses are a rare but serious complication of liver transplants in children. Restoration of flow by radiological methods often provides a viable treatment option. This technique relies on the interventional radiologist’s ability to advance a guide wire across the obstruction, thus allowing for balloon dilatation and other necessary interventions. Failure to cross the stenosis reduces graft survival and increases patient morbidity. We report two cases with tight hepatic vein stenosis where the guide wire could not be advanced in a conventional approach across the upper end of the stenosis. Utilizing prominent intrahepatic collateral vessels, the stenoses were able to be crossed, facilitating successful PTA with good clinical outcome.

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.
