title: Aortic Epithelioid Angiosarcoma after Endovascular Aneurysm Repair.
abstract: We report a case of epithelioid angiosarcoma of the abdominal aortic wall after endovascular treatment for abdominal aortic aneurysm (EVAR). A 60-year-old male, treated 7 years before with EVAR, presented with abdominal back pain, general fatigue, and fever. It was assumed to be a graft infection with periaortic tissue compatible with an inflammatory reaction. The endograft was therefore completely removed and a Dacron silver aorto-bisiliac graft was implanted. After a few days the patient worsened, the angio-computed tomography scan showed a progressive increase of the periaortic mass and numerous small nodules in the abdomen were also detected. The patient was again brought to surgery, an axillo-bifemoral bypass was performed, and the aorto-bisiliac graft was removed but the patient died after surgery. The histological examination showed an aortic epithelioid angiosarcoma with peritoneal metastasis.
