[Uterine vascular abnormalities]

Congenital and acquired vascular abnormalities of the uterus are quite rarely, but they are given much attention in the scientific literature due to the risk of life-threatening bleeding. In the uterus, as in any other organs, malformations can involve vessels of any caliber and type. The review summarizes the materials by clinical characteristics, pathogenesis, diagnostic methods, morphological features and management tactics of patients with uterine arteriovenous malformations. Enhanced myometrial vascularity in the puerperium due to retained placental tissue are also considered. The issues of terminology and differential diagnosis of these conditions are discussed, which is important in connection with significantly different approaches to treatment.
