[Acute occlusion of the iliac arteries after replacement of a total hip (author's transl)].

Two cases of acute occlusion of the external iliac arteries were observed following operative replacement of total hip protheses. They were treated by clot removal. The cause for the acute arterial obstruction presumably are tears of the intima with subsequent thrombosis as well as mobilisation of arteriosclerotic intima-plaques, initiated by traction on the femoral and external iliac arteries which are adherent to their cicatrized perivascular tissues.
