Surgical Therapy for Angiosarcoma of the Aorta: A Case Report.

We describe the case of a 71-year-old woman presenting with abdominal angina with an intra-aortic mass at the thoracoabdominal aorta that restricted blood supply to the organs. Initially, the intra-aortic mass was suspected to be a mural thrombus; thus, endarterectomy was performed. However, postoperative histopathological examination revealed an intimal sarcoma, which relapsed locally within a few months. Additional en bloc resection of the aorta with graft interposition was performed. Despite surgical therapy, splenic metastasis was detected a few months after the second surgery; therefore, palliative care was selected for the patient.
