Novel Use of Lysis-Assisted Covered Endovascular Reconstruction of the Aortic Bifurcation (LA CERAB) in Acute Aortobiiliac Graft Thrombosis: A Case Report
Bibliographic record
Abstract
IntroductionAcute aortic occlusion (AAO) is a rare, life-threatening condition presenting with severe ischemia and requiring urgent intervention. While traditional open surgical approaches, including aortobifemoral and axillobifemoral bypasses, are well-established, endovascular techniques such as Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) have emerged as promising alternatives in select cases. This case introduces a novel modification termed Lysis Assisted CERAB (LA CERAB), combining thrombolysis and CERAB to manage acute graft occlusions.MethodsSingle-institution case report highlighting the utility of the LA CERAB technique in select patients.ResultsA 67-year-old male presented two years post-open aortobiiliac aneurysm repair with acute abdominal pain and bilateral limb ischemia without motor impairment. Initial CTA demonstrated complete thrombosis of his graft. He underwent percutaneous bilateral transfemoral catheter-directed thrombolysis. Post-thrombolysis angiography showed graft patency but significant residual thrombus. Subsequent LA CERAB successfully re-lined the graft, secured residual thrombus, and restored perfusion. The patient had an uneventful recovery, discharged home on therapeutic anticoagulation. Follow-up CTA at 2 months demonstrated sustained graft patency. This case highlights its applicability to acute presentations and adds to a growing body of literature on acute aortic graft occlusion interventions.ConclusionThe LA CERAB technique can serve as a novel, minimally invasive approach for select AAO patients presenting with high morbidity risks for transition open surgery. This case underscores patient-specific considerations in treatment strategy selection, illustrating how individualized surgical approaches can achieve favorable immediate and sustained clinical outcomes for future patients.

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.
