Severe platelet transfusion refractoriness after thoracoabdominal aneurysm repair

Abstract

Severe thrombocytopenia after thoracoabdominal aortic aneurysm repair poses a significant clinical risk in the immediate postoperative period. Understanding the mechanisms of refractoriness to platelet transfusion is relevant to supporting thrombocytopenic patients postoperatively. We present the case of a 76-year-old woman with refractory thrombocytopenia secondary to alloimmunization following open repair of a Crawford extent IV thoracoabdominal aneurysm. The patient provided written informed consent for the report of her case details and imaging studies.
