Angiossarcoma mimetizando endoleak tardio pós-reparo endovascular de aneurisma de aorta infrarrenal: relato de caso

Abstract Whenever a patient who has undergone endovascular repair of an abdominal aortic aneurysm (EVAR) presents with sudden onset abdominal pains or signs of shock, the hypothesis of endoleak with aneurysm expansion and rupture should be considered. We present the case of an EVAR patient in whom a tumor of the duodenum mimicked an endoleak during the postoperative period.
