Abdominal aortic endograft collapse due to false lumen radial force of an acute type B aortic dissection.

We report a case of abdominal endograft proximal collapse due to acute type B aortic dissection in a patient previously treated with endovascular repair (EVAR) for an infrarenal abdominal aortic aneurysm. Patient underwent axillobifemoral bypass grafting, in emergency. The postoperative computed tomography scan showed reexpansion of the occluded endograft. The patient died after 2 days with evidence of progression of the thrombosis of the false lumen and with involvement of renal, visceral, and medullar artery. EVAR collapse associated to acute type B aortic dissection is a challenging condition, which requires aggressive approach.
