Late rupture of knitted Dacron graft.

An 87-year-old man underwent aorto-bifemoral bypass using a bifurcated Bionit II knitted Dacron graft for high aortic occlusion in 1987 at another hospital. In November, 2004, he was admitted to our institution because of difficulty in walking due to swelling and tenderness in the right groin. Computed tomography (CT) scan indicated bilateral aneurysms of the grafts in the groins. The size of the right and left aneurysms were 73 mm and 52 mm, respectively. Angiography showed some extravasation in the right thigh. We performed surgical replacement of all the dilated parts with new ringed-Dacron grafts. We report a rare case of late rupture of bifurcated Sauvage Bionit II Dacron graft.
