Safety of Salvaging Impending Flap Congestion in Breast Reconstruction by Venous Supercharging of the Cephalic Vein
Bibliographic record
Abstract
Autologous flap breast reconstruction is an established technique that carries a risk of vascular failure. We evaluated the safety of salvaging impending venous congestion by using the cephalic vein for supercharging autologous abdominal flaps. Our main outcome measures were flap survival, triggering or impairing lymphedema as measured by the physician or reported by the patient, and scar severity as measured by the Vancouver scar scale. We were able to save 100% of the flaps, but could not find any statistical association with or without increased lymphedema before and after the procedure. One patient reported that lymphedema worsened. The patients accepted the scars (mean Vancouver scar scale score, 5.7). In sum, using the cephalic vein to improve venous drainage of autologous breast reconstruction was safe and did not trigger or impair lymphedema, but scarring in the upper arm was unavoidable.

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.
