Abstract
We report a case of a 52-year-old male who presented with acute leg ischemia and underwent successful femoral embolectomy and fasciotomies. Investigations revealed a pedunculated mass in the aortic arch, floating under the innominate and left common carotid arteries. Urgent resection was performed through a longitudinal aortotomy with deep hypothermic circulatory arrest and axillary artery perfusion to reveal a 2.5 x 1.5 cm pedunculated mass attached to the posterior aspect of the arch that was resected. Histology revealed thrombus material prompting lifelong systemic anticoagulation. On 3 months follow-up, the patient had returned to normal activities and computed tomography confirmed complete resection without recurrence. This case study demonstrates that spontaneous thrombus formation is possible in high-flow vascular regions such as the aortic arch and also confirms the importance of evaluating central sources of thromboemboli in patients presenting with acute limb ischemia. Urgent surgical removal is recommended and can be performed safely.

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 it
