P17.07: Chorioangiomas with signs of fetal compromise on ultrasound evaluation: a case series
Bibliographic record
Abstract
Four cases of chorioangiomas (ChA) diagnosed at the 20-week scan were followed with serial ultrasounds, and progressed from 2-5 cm to a maximum of 8-11 cm. Case 1: Polyhydramnios developed at 28+6 weeks (w) with short cervix and a normal middle cerebral artery peak systolic velocity (MCA PSV). Amnioreduction was performed with subsequent preterm labour and an emergency Caesarean section for malpresentation. The female baby weighed 1450 g with an Apgar of 5-7 and mild anemia (cord hemoglobin (Hgb): 99 g/L). Case 2: MCA PSV increased up to 1.5 MoM at 32 +4 w and remained stable with reassuring fetal wellbeing up to the Caesarean section at 34+2 w, with delivery of a 2530 g male baby with an Apgar of 3-5-7 and mild anemia (cord Hgb: 98 g/L). Case 3: Progressing polyhydramnios with a max ACM PSV of 1.53 MoM at 32 w and development of a pulsatile umbilical vein the next day. Emergent C-section was done because of the modified fetal hemodynamic state. The male baby weighed 1785g with an Apgar of 4-6-9 and no anemia (cord Hgb: 134 g/L). Case 4: MCA PSV was normal throughout pregnancy, but a deeper Doppler A wave of the ductus venosus with on/off umbilical vein pulsatility was noted between 30 and 34 +6/7w, without signs of cardiac failure. A 2600 g female baby was delivered by C-section at 35+4 w, with an Apgar of 8-8 and mild anemia (cord Hgb: 114 g/L).

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.
