Acute Superior Mesenteric Vein Thrombosis With Small Intestinal Ischemia
Bibliographic record
Abstract
Acute superior mesenteric vein thrombosis results in sudden interruption of blood supply to a segment of small intestine leading to ischemia followed by intestinal infarction and necrosis of that segment. Immediate systemic anticoagulation and early surgical intervention are required to remove the infracted segment of bowel to prevent sepsis and death. The mesenteric ischemia due to thrombosis of superior mesenteric vein is a rare condition of the intestine, however intestinal infarction associated with it is even more uncommon. Systemic hypercoagulable state is usually present in most of these patients. I, report a case of 43 years old Caucasian male who presented to the emergency room with severe diffuse upper abdominal and back pains out of proportion of his abdominal findings associated with nausea and vomiting. Past history of deep vein thrombosis (DVT) of lower extremity in the patient and his sister was documented. Computed tomography of abdomen with intravenous contrast revealed superior mesenteric vein thrombosis and extension of thrombus into portal vein along with its segmental branches resulting in ischemia of distal small bowel. The patient was initially treated with systemic anticoagulation but due to lack of response to conservative management for 12 h the patient was taken to operating room and underwent resection of about 2 feet of ischemic distal small bowel with good post operative recovery. Acute superior mesenteric vein thrombosis associated with mesenteric ischemia requires prompt diagnosis, urgent medical and early surgical intervention to prevent sepsis, high morbidity and mortality.

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.
