Report of a Case: Pseudoaneurysm of the Cystic Artery With Hemobilia Treated by Arterial Embolization
Bibliographic record
Abstract
We report a case of hemobilia caused by pseudoaneurysm of the cystic artery in a 71-year-old woman who presented with fever and epigastric colicky pain with jaundice. Liver function tests showed signs of obstructive jaundice. On the second day, patient had a massive hematemesis and melena with hypovolemic shock. Hemobilia was diagnosed by endoscopically visualizing bleeding from the papilla of Vater. An emergent angiography demonstrated the presence of a pseudoaneurysm in the cystic artery. Selective embolization of the cystic artery was then performed to interrupt the blood flow into the pseudoaneurysm. Immediately after embolization, patient was hemodynamically stabilized. Although the patient did not undergo cholecystectomy after embolization due to severe co-morbidities, no signs of ischemic gallbladder have been observed. Hemobilia should be included in the differential diagnosis of upper gastrointestinal bleeding with unknown etiology. Embolization could be an option for pseudoaneurysms of the cystic artery especially in high-risk patients. doi:10.4021/jmc249w

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.
