False aneurysm in an ileofemoral Dacron graft after total hip arthroplasty.

A 54-year-old woman patient had received a complete Zweymüller-type prosthesis of the left hip 9 years previously. The heat generated by the setting of the cement produced a thrombosis of the common femoral artery, and an ileofemoral Dacron graft was made. After the 9 year period, the acetabular component was clearly loosened, and a replacement was attempted during which the existence of a pseudoaneurysm, the result of erosion of the Dacron graft by the cement pin, was discovered.
