Popis: Endoleaks remain a main concern in endovascular aneurysm repair. A potential false positive in the diagnosis of endoleak surveillance includes "billowing," a phenomenon of the polytetrafluoroethylene plastic outer fabric of the stent graft is seen separated from the struts of the metallic endoskeleton. Contrast presents beyond the endoskeleton but is still contained within the graft. This is secondary to intermittent attachment of the graft to the endoskeleton, and is only found in the Endologix Powerlink. The finding of billowing has been previously reported and is a common knowledge by those who deploy the stent graft. We report a case where there is contemporaneous imaging on computed tomography angiography as well as on ultrasound.
