Rupture of a Totally Occluded Abdominal Aortic Aneurysm.

Totally occluded aortic aneurysm is a rare pathology. The medical history and the evolution are unknown. We present a case of a regularly followed up 60-year-old man with chronic thrombosed aneurysm, presenting with mycotic acute rupture. As an original treatment, the patient was treated by aortic ligation without distal revascularization. A literature review from 1974 to 2015 enhances the contemporary understanding of the pathology, by exploring the thrombus interaction, pressure, and the wall shear stress. The literature review confirms the poor prognosis and concludes of a necessary closer follow-up for chronic occluded aneurysm.
