To the doctrine of the retention and accretion of the placenta

Bearing in mind the conflicting opinions of the authors regarding the essence of the reasons for the delay of the placenta near the walls of the uterus and the extremely insufficient number of microscopic studies of cases, the so-called increment of the placenta, in the winter of 1895 - 1896 I took the trouble to make an attempt with the help of a microscope to get acquainted with the nature of pathological changes, taking place with the increment of the placenta. Unfortunately, my material was extremely modest in quantitative terms: it always covers two cases, the drugs for which are in the museum of the clinic of prof. Slavyansky. Both of these cases are destined to reappear on the pages of the special press: seventeen years ago, both of them served as material for Dr. Imshkarov's dissertation (Atonia partialis uteri ex metritide interstitial! Chronica. Diss., St. Petersburg, 1880) and their description detailed in this work. Introducing ourselves, thanks to the kind permission of prof. KF Slavyansky, with these preparations stored in excellent condition in the museum of the clinic, I took a small piece from them for microscopic examination of those parts of the uterine wall on which the adherent pieces of the placenta were sitting.
