“…This association did not change even after adjustment for various confounding factors. The overall rate of hysterectomies in our study was 3.96%, which is lower compared to the results of other studies [3,11]. Most of the hysterectomies occurred in women with placenta accreta.…”

“…So far, the only factor that was found to significantly increase the risk of placenta accreta development in women with PP was a history of previous cesarean section. Women with PP and 3 or more cesarean sections had more than 60% chance for the development of PP [11]. The connection of different types of PP and placenta accreta was for the first time described in the literature by Gorodeski and Bahari who found connection of marginal PP with placenta accreta with focal accretion [4].…”

Objective:To determine the incidence, obstetric risk factors and perinatal outcome of placenta previa. Study design: All singleton deliveries at our institution between 1990 and 1998 complicated with placenta previa were compared with those without placenta previa. Results: Placenta previa complicated 0.38% (n = 298) of all singleton deliveries (n = 78 524). A back-step multiple logistic regression model found the following factors to be independently correlated with the occurrence of placenta previa: maternal age above 40 years (OR 3.1, 95% CI 2.0-4.9), infertility treatments (OR 3.1, 95% CI 1.8-5.6), a previous Cesarean section (OR 1.8, 95% CI 1.4-2.4), a history of habitual abortions (OR 1.3, 95% CI 1.3-2.7) and Jewish ethnicity (OR 1.3, 95% CI 1.1-1.8). Pregnancies complicated with placenta previa had significantly higher rates of second-trimester bleeding (OR 156.0, 95% CI 87.2-277.5), pathological presentations (OR 7.6, 95% CI 5.7-10.1), abruptio placentae (OR 13.1, 95% CI 8.2-20.7), congenital malformations (OR 2.6, 95% CI 1.5-4.2), perinatal mortality (OR 2.6, 95% CI 1.1-5.6), Cesarean delivery (OR 57.4, 95% CI 40.7-81.4), Apgar scores at 5 min lower than 7 (OR 4.4, 95% CI 2.3-8.3), placenta accreta (OR 3.6, 95% CI 1.1-9.9) postpartum hemorrhage (OR 3.8, 95% CI 1.2-10.5), postpartum anemia (OR 5.5, 95% CI 4.4-6.9) and delayed maternal and infant discharge from the hospital (OR 10.9, 95% CI 7.3-16.1) as compared to pregnancies without placenta previa. In a multivariable analysis investigating risk factors for perinatal mortality, the following were found to be independent significant factors: congenital malformations, placental abruption, pathological presentations and preterm delivery. In contrast, placenta previa and Cesarean section were found to be protective factors against the occurrence of perinatal mortality while controlling for confounders. C onclusion: Although an abnormal implantation per se was not an independent risk factor for perinatal mortality, placenta previa should be considered as a marker for possible obstetric complications. Hence, the detection of placenta previa should encourage a careful evaluation with timely delivery in order to reduce the associated maternal and perinatal complications.It is accepted that placenta previa poses severe hazards to both mother and fetus 1-4 . Several studies have attempted to discover various epidemiological factors associated with this condition. Major risk factors found to be associated with placenta previa were previous Cesarean

“…With a sizable proportion of childbearing women in our society being grandmultiparae, the risks of repeat caesarean section especially placenta praevia accreta increases. It was shown by Zaki et al (1998) that the incidence of emergency hysterectomy in cases of placenta praevia accreta was 50% compared to 2% in non-accreta. It will therefore seem reasonable to attempt to reduce the trend of caesarean section for breeches in our community.…”

A retrospective study that was conducted on 755 singleton breech deliveries over a 7-year period between January 1994 and December 2000 at a referral hospital in Saudi Arabia showed that it represented 3.35% of all deliveries. There was a statistically significant trend in caesarean section (P = 0.001) accompanied by a modest linear trend in perinatal mortality (P = 0.049). There were no statistically significant differences in the mean age, parity and birth weight when the women delivered during each year were compared (P > 0.05), but there were statistically significant differences in the gestation at delivery (P < 0.05). Furthermore, statistically significant differences were found in the trends of the preterm breech deliveries and booking status over the period of study (P > 0.05). However, there was no statistically significant linear trend in the birth trauma (P > 0.05). Nineteen cases of the fetal birth trauma (67.8%) were associated with vaginal breech delivery while nine cases (32.2%) were reported from caesarean section. This was statistically significant (P = 0.00074). The role of selective external cephalic version as a way of reducing the caesarean section rate and also trauma during vaginal breech delivery at term in our community is discussed.
