P17.07: Chorioangiomas with signs of fetal compromise on ultrasound evaluation: a case series
Bibliographic record
Abstract
Objectives: Club foot is one of the most common congenital limb deformities.A considerable number of malformations, genetic syndromes, neuromuscular diseases or aneuploidies can be associated.When club foot is prenatally diagnosed, management across centre is not consensual.The objective of our study was: 1. to assess ultrasound diagnostic accuracy and 2. to evaluate the usefulness of examination performed.Methods: All cases of infants born between 2014 and 2018 with unilateral or bilateral club foot deformity identified in French Occitanie region and systematically referred to a single physiotherapist were retrospectively collected.Based on these born children, we retrieved their prenatal sonographic images and ultrasound description (isolated/associated malformation), and collected pregnancy management (screening and testing) and compared it with postnatal outcomes.We also collected all cases of TOP during this time period were children had a club foot among other trouble.Results: 217 children were included.The diagnosis was made prenatally in 69% of cases.Ultrasound diagnosis was concordant in 86% of cases regarding laterality.An associated pathology with club foot was found in 11% of children.The proportion of uni/bilateral club foot was the same in the associated and isolated forms (p = 0,8).An incorrect prenatal diagnosis of isolated or associated character was found in 8% of cases.Amniocentesis was offered to 74% patients, with only 39% acceptance (microarray analysis performed in 62% amniocentesis).Aneuploidy was found for 4 children and a microdeletion syndrome for one child.42 TOP had been performed during that period and all cases had an associated club foot.Conclusions: When a club foot is prenatally diagnosed, management should include: 1. a specialised ultrasound examination to confirm diagnosis, characterise the malformation and look for associated abnormalities and 2. genetic counselling to offer amniocentesis with microarray analysis regardless of uni/bilateral or isolated/associated status.

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.
