title: [Disputable problems of the pathogenesis of implantation of the placenta into the uterine wall].
abstract: The review analyzes publications on the clinical and pathomorphological diagnosis of implantation of the placenta (placenta accreta) (500 references). It characterizes the prevalence of placenta accreta in different countries of the world and a rapid increase in this indicator because of a rise in cesarean sections with further uterine scars. The clinical variants, major pathomorphological types, risk factors of this severe puerperal obstetric complication and the existing hypotheses of its pathogenesis are given. Promises for further studies of the mechanisms for implantation of villi and surrounding components of the uterine placental bed are denoted.
