[Cinedensitometric documentation of a catheter-induced spasm in the carotid siphon (author's transl)].

During a transfemoral cerebral angiography spasm of the carotid siphon was to be observed. This circulatory disturbance has been recorded by angiocinematography and evaluated by cinedensitometry. The analysis of the catheter-induced spasm is intended as a contribution to the etiology and the pathophysiology of vasospasm in man.
