Right pneumonectomy syndrome presenting as a cardiac arrest in a two-year-old
Bibliographic record
Abstract
INTRODUCTION: Pneumonectomy syndrome is a rare complication after pneumonectomy with variable onset and presentation. It is characterized by extrinsic airway compression secondary to mediastinal shift. As far as we are aware, we are reporting the first pediatric case of pneumonectomy syndrome presenting as a cardio-pulmonary arrest. PATIENT AND INTERVENTION: A two-year-old boy presented with a cardiac arrest 8 months after his pneumonectomy. He failed extubation twice. A flexible bronchoscopy was then performed which revealed external compression of the left mainstem bronchus. He underwent surgical correction with a prosthetic, thoracic implant. RESULT: The patient's trachea was subsequently extubated to room air on postoperative day 1. He remains clinically stable at 6 month follow-up. CONCLUSION: Postpneumonectomy syndrome is a rare but serious complication after pneumonectomy. If the airway compression occurs in conjunction with compromised vena caval return, cardio-pulmonary arrest can occur. Therefore, timely diagnosis and early intervention is required.

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.
