Penile angiography in impotence: local experience.

Vasculogenic causes of impotence and especially venous leakage are now considered to be significantly worthwhile to be evaluated in the light of new developments and changes in the treatment of erectile dysfunction. The investigations of cavernosography and penile arteriography are gaining importance. In 32 months, from August 1990 to March 1993, 126 cavernosograms and 11 bilateral internal pudendal arteriograms have been performed on patients from Toa Payoh Hospital. Smooth muscle relaxants are helpful in both procedures. Nearly three-quarters of the cavernosograms showed deep venous leakage. The use of arteriograms is still very restricted. The many variations of the arterial supply to the penis pose problems in the interpretation of the arteriograms and hence, recognition of the numerous variations besides the knowledge of the normal basic vascular anatomy is of paramount importance.
