Abstract
We present a case of a 4.2-cm hepatic artery aneurysm following remote pancreaticoduodenectomy, which extended to the first division of the right hepatic artery. Given the absence of collateral flow from the superior mesenteric artery (SMA) and the inability to place a covered stent, we treated the patient with a saphenous vein graft to the right hepatic artery bifurcation. A CT scan at 1-year demonstrated a patent bypass to the right hepatic artery. We would advise caution when considering hepatic embolization following pancreaticoduodenectomy due to loss of SMA-based collaterals. Techniques that preserve arterial flow should be favored in this situation.

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 it
