Pulmonary sequestration causing severe cardiac failure requiring lobectomy in an extreme preterm infant
Bibliographic record
Abstract
We report a case of a large, extralobar pulmonary sequestration in a preterm infant born at 25 weeks gestational age. A computed tomography (CT) angiogram demonstrated that the arterial supply arose from the celiac trunk while an abnormally large, single left pulmonary vein drained the sequestration. This, along with the large patent ductus arteriosus (PDA), created a double left to right shunt, which resulted in severe, high output cardiac failure. Despite aggressive medical management for 3 weeks, he remained critically ill and developed renal failure. Therefore, after multiple, extensive multi-disciplinary discussions with the family, resection was offered as the only possibility for survival. He underwent a left thoracotomy and resection of the extra-lobar sequestration, which was occupying the lower two-thirds of his left hemithorax. To our knowledge, this is the youngest patient in the literature to undergo resection of an extra-lobar sequestration. Management challenges in terms of balancing the cardiac failure against the timing, approach and success of surgical intervention are also discussed along with a review of the literature.

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.
