ABSTRACT: Background: Placenta previa (P.P) is a rare pregnancy
complication where a placenta particularly or completely covers the internal
cervical os thereby preventing normal vaginal delivery. This study was
conducted to evaluate the relationship between repeated cesarean deliveries and
subsequent development of placenta previa. Methods & Materials: This cross-sectional study was held in
Imam Reza Hospital Kermanshah-Iran during 2008-2011. This study included all
pregnant women with repeated cesarean sections while nullipara and patients
with placenta previa without previous surgery were excluded. Diagnosis was made
on ultrasound and at surgery. Results:
among 2696 Women, 98 cases had P.P (3.63%). The mean age was 30 years, 76.5%
(75 cases) had gravidity 2 and 3 and 87.8% (86 cases) had parity 1 - 3. Anterior
location of placenta was 44.9% while posterior was 55.1%. 48% were complete
P.P, 32.7% low lying P.P, 13.3% marginal P.P, and 6% Partial P.P. 26.5% of
patients had history of abortion. 55.1% of patients had male fetus. There was
an increase in frequency of placenta previa with just one previous C-section
(74.5%). Frequency of accreta P.P 32% (n = 7), increta (14.3%, n = 3) and
percreta 28% (n = 6). Among those who underwent emergency hysterectomy (21
cases) 23.8% cases had no abnormal placentation. 30.6% of newborns had birth
weight
