Uterine artery pseudoaneurysm with an anastomotic feeding vessel requiring repeat embolisation
Bibliographic record
Abstract
Uterine artery pseudoaneurysm (UAP) is a rare cause of delayed postpartum haemorrhage. Early diagnosis and endovascular management are effective in treating this condition. We present the case of a 36-year-old gravida 3, para 2 woman with delayed postpartum haemorrhage and endometritis following a spontaneous vaginal delivery. Ultrasound and catheter angiogram demonstrated a UAP arising from the distal aspect of the left uterine artery. Significant bleed persisted despite selective bilateral uterine artery embolisation. A repeat angiogram confirmed complete occlusion of bilateral uterine arteries, but abdominal aortogram demonstrated that the left ovarian artery was now feeding the pseudoaneurysm. A repeat embolisation procedure was performed to occlude the left ovarian artery. The patient was discharged the following day. Selective arterial embolisation is effective in the management of UAP. Persistent bleeding despite embolisation should raise the suspicion of anastomotic vascular supply and may require repeat embolisation.

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.
