<b>Intramural Hematoma of the Arch and Ascending Aorta Owing to Acute Aortic Syndrome of the Descending Aorta:</b> To Stent or Not to Stent?
Bibliographic record
Abstract
PURPOSE: To report thoracic stent-graft repair in patients with acute aortic syndromes, an intramural hematoma (IMH), and intractable pain despite maximum medical therapy. CASE REPORTS: Since January 2002, 4 patients [2 men (40 and 53 years old) and 2 woman (62 and 83 years old)] with type B aortic dissection have presented with an IMH >3 mm in the aortic arch. The patients were treated with a "freeflo" Valiant thoracic stent-graft, which was deployed under "zero aortic pressure" using either adenosine arrest or rapid ventricular pacing. To enhance false lumen thrombosis, a distal extension was inserted when a significant re-entry was observed in the mid third of the descending thoracic. The procedures were successful; over a follow-up ranging to 17 months, the patients have been asymptomatic, with resolution of all the IMHs. CONCLUSION: Thoracic stent-graft treatment of acute aortic syndromes of the descending aorta complicated by arch IMH is feasible. Success of the procedure may rely on optimal stent-graft selection with minimal graft oversizing, deployment under "zero aortic pressure" using rapid ventricular pacing, and more liberal revascularization of the left subclavian artery.

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.
