Bilateral internal pudendal artery-urethral fistula formation by pseudoaneurysm

Abstract

Posttraumatic fistula between the internal pudendal artery and urethra is rarely reported in the literature. We report a case of bilateral internal pudendal artery-urethral fistula formation by pseudoaneurysm, following a blunt pelvic trauma in which superselective angiography revealed the site of bleeding. The fistula was treated with superselective arterial embolization.
