The morbidity and mortality associated with this complication is significant with an overall mortality rate of 15-20% and a graft loss rate of 55-70%. Currently the gold standard treatment for mycotic pseudoaneurysms is undefined. Recently there have been three renal transplant patients at the University of Alberta Hospital who developed mycotic pseudoaneurysms with different surgical repairs and outcomes. We performed a quality assurance review and a literature review of the surgical management of mycotic pseudoaneurysms. Based on this review, we have proposed a novel management pathway which may help reduce post-operative complications. METHODS: The databases MEDLINE and SCOPUS were searched for all case reports describing management of mycotic pseudoaneurysms in renal transplant patients between years 1990-2022. RESULTS: Twenty-two articles were reviewed which described forty-one case reports of mycotic pseudoaneurysms in renal transplant recipients. Repair techniques included patch repair in 61% of cases (25/41), endovascular stenting in 22% of cases (9/41), and extra-anatomical bypass in 12% of cases (5/41), 5% of patients (2/41) had a post-mortem diagnosis. The failure rates of patch repair resulting in death or repeat surgery was 44% (11/25), failure rates for stents was 22% (2/9), failure rates of extra-anatomical bypass was 0%. Every patient who required a takeback operative procedure was managed with an extra-anatomical bypass. Overall patient mortality was 17% (7/41), overall graft loss rate was 68% (28/41). CONCLUSIONS: Considering the high failure rates of patch repairs and endovascular stents, we suggest the first-line strategy for repair should be an extra-anatomical bypass with the assistance of Vascular Surgery when possible. If an extra-anatomical bypass cannot be performed, we suggest a wide surgical debridement with autologous in-line reconstruction. These surgical approaches may help decrease the incidence of surgical failure rates and mortalities. Having a standardized management pathway utilized by Transplant Urology and Vascular Surgery may allow for improved patient surgical outcomes and graft survival outcomes in the future.

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.
