A Case of Septic Portal Vein Thrombosis in a 71-Year-Old Female
Bibliographic record
Abstract
Portal vein thrombosis (PVT) is a relatively rare condition that is characterized by partial or complete occlusion of the portal vein. The most common risk factors for developing PVT are a result of a low intra-hepatic vein flow or pro-thrombotic states, including underlying liver disease, coagulopathies, infection, and malignancy. Patients with PVT can present asymptomatically, while others are in profound shock. Clinical manifestations vary based on the location of the thrombus, degree of occlusion, and if it has become infected. Although an uncommon source of sepsis in the emergency department (ED), maintaining a high degree of clinical suspicion for septic PVT is critical as there are additional treatment considerations apart from early antibiotic therapy as in general sepsis. The following case report focuses on a 71-year-old woman with a septic PVT who presented to the ED with fever and hypotension in the absence of known risk factors. Current management guidelines and evidence regarding treatment strategies for septic PVT are also discussed in further detail.

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.
