Large Free-Floating Intra-Aortic Thrombus
Bibliographic record
Abstract
A 56-year-old woman was admitted with chronic chest and back pain with recent exacerbation.Cardiac enzyme levels and ECG were normal.Her history was positive for a patent ductus arteriosus ligation at 13 years of age and a total left mastectomy owing to cancer 4 months earlier.Her son died at 30 years of age as a result of type A aortic dissection.A chest computed tomography revealed a large floating mass inside the descending aorta attached to the aortic wall adjacent to the left subclavian artery (Figure 1).Magnetic resonance imaging showed a 12-cm, well-defined, pedunculated, homogenous mass (Figure 2 and Data Supplement Movie).At operation, a long (11ϫ1.5 cm), pedunculated, well-organized mass attached to an atherosclerotic plaque distal to the left subclavian artery was found (Figure 3).The highly mobile mass and the adjacent aortic wall incorporating the ulcerated atherosclerotic plaque were removed.On microscopic examination, the presence of a thrombus and the atherosclerotic changes of the aortic wall were confirmed.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
