from
adhesions from endometriosis or from an old healed inflammatory
process, occasionally
plays a part. Submucous fibroids may be
a silent or symptomatic
cause.

PLACENTA
PREVIA
Placenta previa is a term used to describe implantation
of the placenta within the lower uterine segment. This
phenomenon
occurs in 0.5 to 1.0 per' cent of pregnancies in the third
trimester; a higher incidence in early pregnancy is explained
by the fact that the condition is frequently associated with
early abortion. The classification of placenta previa depends
on the degree of coverage of the lower uterine segment.
In
placenta previa centralis the internal cervical os is totally
occluded by the placenta; placenta previa marginal is
indicates
a partial encroachment upon the os;low implantation of the
placenta is used to describe placentas which are attached to
the lower uterine segment. Advancing maternal age and
increasing parity predispose to the development of placenta
previa; the condition is perhaps related to defective
vascularization of the decidua or unfavorable uterine environment
shortly after
conception.
