Aseptic necrosis of the right horn of an abnormally developed uterus after ligation of the ascending branch of the right uterine artery

Background: Malformations of internal genital organs have various clinical manifestations. Anatomical structural abnormalities of the genitals can cause serious complications in obstetric practice. Case report: The paper describes a case of necrosis of the right horn of a bicornuate uterus, which results from ligation of the ascending branch of the right uterine artery. It depicts the clinical presentations and presents the data of additional studies. Particular emphasis is placed on the causes of delayed diagnosis of complications. A brief review of the literature on this problem is given. Conclusion: The cause of uterine necrosis was the ligation of the ascending branch of the right uterine artery, which was the only source of blood supply to the right uterine horn of the abnormally formed uterus. Uterine necrosis can be timely diagnosed, by comparing its clinical presentation with additional diagnostic test data (the absence of the normal uterine architectonics, the presence of gas bubbles in the myometrium, and its avascularization). Congenital malformations of the internal genital organs are accompanied not only by a change in their anatomical shape, but also by their impaired blood vessel formations, which should be taken into account when examining and delivering patients with this pathology.
