RESUMO
Congenital arteriovenous malformations in the true pelvis are extremely rare : only 8 cases have been described in male patient. In most cases, the diagnosis may be obscure and the management is difficult due to frequent recurrence, so appropriate angiographic study is decisive in establishing the diagnosis and directing the mode of treatment. We report on 53 year old male patient who was treated with embolization due to congenital pelvic arteriovenous malformation with painless gross hematuria after erection or sexual intercourse. Diagnosis was established as periprostatic pelvic arteriovenous malformation by means of transrectal color Doppler ultrasonography and confirmed by angiography. Our attempt at management by embolization is described. A literature review and discussion of congenital arteriovenous malformation and worth of color Doppler ultrasonography are presented.
