Abstract
OBJECTIVE: The main objective of this study was to describe the visceral and renal vessel involvement and the outcomes in thoracic dissections. METHODS: Computed tomography scans of 39 patients were reviewed (30 type B, 9 type A). Visceral and renal arteries were recorded as perfused by the true lumen (TL) or false lumen (FL). Radiologic follow-up was 3.3 years (range 0-10). RESULTS: A total of 156 vessels were analyzed, and 49 (31%) were supplied by the FL. The most common patterns were FL supply of a renal artery (RA) with the visceral arteries and contralateral RA from the TL. In the follow-up, branch vessel compromise occurred in 12 vessels and was more likely to occur when supplied by the FL (P = .01). About 75% of the patients with at least 2 vessels supplied by the FL demonstrated aortic dilatation. CONCLUSIONS: Branch vessel occlusion is more likely in the vessels supplied by the FL. Aortic dilatation occurred more frequently when 2 or more vessels were supplied by the FL.

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
