RESUMO
Dacron vascular prostheses have been widely used in vascular surgery since the mid-1970s. They have been proven to be the most durable and reliable conduits for arterial replacement in aortic and peripheral surgeries for decades. However, an extremely rare complication, namely late non-anastomotic graft rupture, due to intrinsic structural prosthetic disruption can occur, resulting in acute hemorrhage or false aneurysm formation. We report a case of this rare complication due to non-anastomotic rupture of a bifurcated knitted Dacron aortic vascular graft in a patient who had undergone an aorto-bi-iliac bypass 6 years ago. The patient was successfully treated in an emergency setting with endovascular therapy using an iliac limb of an abdominal aortic endoprosthesis.
