Direct-Puncture-Guided Sharp Recanalization Technique in a Case of Long-Segment Superior Mesenteric Vein Occlusion
Bibliographic record
Abstract
Abstract We describe the case of a moderately long chronic superior mesenteric vein (SMV) occlusion following Whipple procedure. Anticoagulation therapy and traditional recanalization techniques through retrograde approach, collateral inferior mesenteric venous vasculature, and recanalization upstream of the SMV occlusion via direct transabdominal puncture failed. Sharp recanalization downstream of the occlusion via retrograde approach, using the stiff end of a glidewire sharpened with a blade, with guidance from the tip of a catheter placed upstream of the occlusion as a target was successful. Our rendezvous technique, combined with use of orthogonal views, allowed for increased precision and decreased risk of catastrophic extravasation.

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.
