Multiple aneurysmal dilatations in a knitted dacron velour graft.

The formation of multiple aneurysms in the midportion of Dacron grafts has been reported only twice in the surgical literature. In the present case, three aneurysmal dilatations developed 6 years following an orto-femoral Dacron graft implantation. Multiple structural defects in the Dacron prosthesis appear to be the most likely cause of the graft failure.
