Twenty-three patients complaining of impotence were examined angiographically as part of their investigation. In all patients, DSA as well as conventional angiography was carried out. The purpose of this investigation was to compare the two methods with regard to their diagnostic value. By means of sequential analysis it was shown that, with an error level of 10%, DSA was superior to conventional angiography.
