[Iliac vessels malformations as a cause of gluteal varices].

Gluteal varices are caused by different malformations (congenital or other disorders) within pelvic vessels. They are usually congenital, rarely acquired disorders. The rarity of incidence, diagnostic difficulties and sometimes ineffective methods of treatment made the authors of this article to present a case of 51-year-old patient with hemorrhoids with concomitant left gluteal varices caused by internal iliac artery-vein fistula.
