Compressions for Portal Vein Air Embolism Evacuation
Bibliographic record
Abstract
Laparoscopic entry into the abdomen with subsequent insufflation can be achieved via an open or closed approach. A risk that is often overlooked as a result of its rarity is a venous air embolism (VAE) from carbon dioxide (CO 2 ) insufflation. Although both closed and open techniques of entry into the abdomen contribute to an extremely low risk for VAE, when the effects are clinically significant the mortality rate has been reported to be as high as 28%. In this report we present a case of a 64-year-old female who underwent a closed approach for entry into the abdomen for elective hepatic cystectomy, who subsequently went into cardiopulmonary arrest and was found to have imaging findings suggestive of VAE localized to the portal vein. Successful management decisions presented in this case report will serve as possible options for physicians to employ when encountering a similar intraoperative complication.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
