Atypically Taut Superior Polar Splenic Artery Discovered in a Human Cadaver
Bibliographic record
Abstract
The splenic artery is the largest branch of the celiac trunk and frequently presents with anatomical variability. These variations relate to its origin, trajectory, location relative to the pancreas, terminal branching pattern, and the potential presence of polar arteries. Knowledge of the splenic artery's variability may inform gastrointestinal surgeons as they plan and execute surgical interventions, resulting in improved success rates while minimizing both operative complications and procedural time. The case presentation of a splenic artery dissected from an elderly male cadaver initially demonstrated normal anatomical arrangement. The artery branched off the celiac trunk of the abdominal aorta and followed a tortuous suprapancreatic route to split into two lobar arteries terminating in the spleen. However, upon closer inspection, a superior polar splenic artery was uncovered with two unique characteristics. Firstly, the presented polar artery lacked branching gastric arteries, a rare variation with a prevalence of only 3.27%. Secondly, the distance between the origin of the superior polar splenic artery and the splenic hilum was greater than what is often reported in clinical literature. While similar previous case reports have observed arterial origins of greater distance, these have often been accompanied by a compensatory arterial length. Interestingly, the case presented in this report contained a superior polar splenic artery with an arterial length shorter than its distance to the splenic hilum, resulting in an atypically taut vessel. This bears clinical importance, as this arterial presentation may be susceptible to a surgical rupture if neglected. By including this anatomical variation in the expanding library of splenic artery variations, surgeons and their collaborative healthcare teams may broaden their understanding of splenic artery anatomy as they conceptualize new techniques for pancreatomy and splenectomy procedures that consider arterial variations while minimizing surgical complications, operative time, and patient blood loss.

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.
