Abstract
OBJECTIVES: Twin-twin transfusion syndrome (TTTS) is associated with a high risk of perinatal morbidity and mortality. The condition results from intertwin vascular connections in the shared placenta. We report here a case of early, severe TTTS that failed to respond to serial amniocenteses and that was successfully treated by means of superselective laser coagulation. METHODS: A causative arteriovenous anastomosis was identified by means of prenatal obstetrical sonography, using color and spectral Doppler techniques. At fetoscopy, performed at 23 weeks' gestation, laser occlusion of only this connection was achieved. RESULTS: This therapeutic intervention resulted in rapid resolution of all evidence of TTTS and a successful pregnancy outcome, with subsequent delivery of 2 healthy infants at 33 weeks' gestation. CONCLUSIONS: The potentially fatal pathophysiology of TTTS was reversed by interruption of a single arteriovenous connection. We have termed this the sonographically evaluated, laser-endoscopic coagulation for twins ('Select') procedure.

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
