Pulmonary sequestration 1: right lower lobe
Bibliographic record
Abstract
Pulmonary sequestration is a rare congenital anomaly, characterized by aberrant lung tissue supplied by an aberrant systemic artery or arteries coursing within the inferior pulmonary ligament. The intralobar variety is the most frequent form. Clinical presentation may include recurrent haemoptysis and infection. Standard treatment involves surgical resection of the affected tissue with maximal preservation of healthy lung. This video tutorial presents the surgical technique for resecting intralobar pulmonary sequestration involving the right lower lobe. Rather than attempting to skeletonize the frequently friable aberrant artery(ies), the lung is mobilized, and the inferior pulmonary ligament containing the aberrant artery is isolated before being divided en masse; in this way, one may decrease the risk of intraoperative arterial injury and haemorrhage. Subsequent lung resection is performed in the standard fashion, in this case, an S10 segmentectomy. Transarterial embolization has been described both as a definitive treatment and as a preoperative intervention to decrease the risk of intraoperative bleeding. In the case of preoperative embolization, one must be wary to avoid embolic material when positioning the vascular stapler to divide the aberrant artery.

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.
