[Color Doppler echography of the cavernous bodies after F.I.C. in the study of erectile impotence of vascular origin].
Study with the Doppler method has been associated with "cavernometrics" and "cavernography" in erection pathologies for some time. But this enquiry is burdened not only be technical inaccuracies such as the lack of knowledge of the angle of incidence of the doppler wave and the diameter of the explored vessel etc, but also by intrinsic difficulty method itself. Therefore, the authors have used a color Doppler to individuate and study the cavernous arteries, and present the results obtained from a group of 21 patients, all affected by erectile deficits, who were selected on the basis of anamnestica and clinical criteria. They individualized 21 patients in whom the vasculogenic nature of their affection appeared probable, out of the 125 who were under their observation for their sexual inadequacy. In three patients the clinical suspicion of a venous incompetency was confirmed by dynamic "cavernometrics with cavernography". The study of the four phases of erection (flaccidity, tumescence, erection, detumescence) was carried out after an intracavernous injection of 20 micrograms of PGE/1. The parameters considered were: systolic velocity of the hematic wave, diastolic speed, the index of resistance and range. In cases of vasculogenic impotence with an arterial base the systolic wave in the 2nd and 3rd phases presented a speed inferior to the norm of standard values, the resistance index altered by the lacking of physiological increment due in the erectile beyond the closing of venous "polsters", also to the rigidity of the albuginea.(ABSTRACT TRUNCATED AT 250 WORDS)
