Embolization for Hemoptysis—Angiographic Anatomy of Bronchial and Systemic Arteries
Bibliographic record
Abstract
Abstract Massive hemoptysis is a potentially fatal respiratory emergency. The majority of these patients are referred to interventional radiology for bronchial artery embolization (BAE). Immediate clinical success in stopping hemoptysis ranges from 70 to 99%. However, recurrent hemoptysis after BAE is seen in 10 to 55% patients. One of the main reasons for recurrence is incomplete embolization due to unidentified aberrant bronchial and/or non-bronchial systemic arterial supply. This pictorial essay aims to describe the normal and variant bronchial arterial anatomy and non-bronchial systemic arterial feeders to the lungs on conventional angiography; the knowledge of which is critical for interventional radiologists involved in the care of patients with hemoptysis.

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.
