The Authors present a case report of a 69-year-old male with a known history of hypertension and previous abdominal aortic aneurysm (AAA) repair, who presented with gastrointestinal bleeding and was diagnosed with AAA and aortoenteric fistula. The patient underwent endovascular repair of intrarenal AAA and femoral-femoral bypass. However, postoperatively, he developed severe thrombocytopenia with persistent low platelet counts despite platelet transfusions. Hematology consultation was obtained, and the patient showed a positive response to intravenous methylprednisolone therapy. This case highlights the occurrence of thrombocytopenia as a complication following AAA surgery and the successful management with corticosteroids.
