Reduction of fibrin deposit in PP cases may be
due to vascular and antithrombotic changes. Further
research is necessary in this issue. It has also
been reported that Nitabuch's fibrinoid layer is
thinned or missed in PP (23). Normally in a pregnancy,
the placenta attaches to the uterine wall
and is separated from the uterus by Nitabuch’s
fibrinoid layer. Under normal circumstances, as
the placenta develops, it grows only within the
endometrium and is clearly separated from the
myometrium and the decidua basalis by Nitabuch’s
layer. This separation is important, because
under normal circumstances, after the childbirth,
the placenta is cleanly separated from the uterus at
this level and the maternal endometrial blood ves
