[Technical problems in interventional angiography (author's transl)].

Interventional angiography has greatly developed recently, as a consequence of a better definition of clinical indications, the progress and the diffusion of the angiographic techniques and finally as a consequence of the technological improvements of angiographic material and accessories. A synthetic study of the actual technical knowledge and of the perspectives of further improvement, is presented, on the basis of a 10 years' experience, during which more than 500 therapeutical interventions have been performed by means of angiographic techniques.
