Ruptured aortic aneurysm with previous endovascular aneurysm repair in a patient with high-grade angiosarcoma

Abstract

Ruptured aortic aneurysms after endovascular repair is rare, particularly in the absence of type I or type III endoleaks. In such cases, a thorough investigation into the causes is imperative, including the consideration of an underlying malignancy. We report a case involving a 78-year-old woman who experienced abdominal aortic aneurysm rupture 4 years after aortic endograft treatment. We explanted the endograft and performed aortobi-iliac bypass. Initial aortic thrombus pathological analysis revealed atherosclerosis. However, the patient returned 4 months later with multiple lesions suggestive of metastases, and a reevaluation of the pathology slides uncovered a diagnosis of angiosarcoma.
