Bilateral high origin and superficial trajectory of the deep femoral artery: clinical and applied anatomy
Bibliographic record
Abstract
The anatomy of the femoral triangle is explored in various approaches, ranging from pulse verification to invasive catheterization procedures. Within the femoral triangle, the deep femoral artery is one of the vessels reported to present several anatomical variations that must be considered before clinical or surgical interventions. Here, we are reporting a unique bilateral variation of the deep femoral artery for medical education purposes and reflecting on its applied, surgical, and clinical anatomy. During the dissection of the femoral triangle, we observed that the deep femoral artery originated in the vicinity of the inguinal ligament and ran in parallel with the femoral artery in a superficial trajectory on both sides of the donor. On the right side, the DFA continued superficial for 8.8 cm, with an origin of 1.2 cm inferior to the inguinal ligament. On the left side, it presented a similar anatomical arrangement, though with an origin of 1.6cm inferior to the inguinal ligament and a superficial course of 5cm. The position of the lateral circumflex femoral vein posterior to the deep femoral artery played a role in this distinctive, lengthy, and superficial presentation of the deep femoral artery. This anatomical variation directly affects surgical procedures, diagnostics, and endovascular interventions. A deep femoral artery with such a lengthy superficial trajectory can be mistakenly used for catheterization instead of the femoral artery or be injured, disrupting the main blood supply of the thigh muscles.

How this classification was reachedexpand
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.
