Placenta Accreta Spectrum

Objective: Placenta Accreta Spectrum (PAS) affects approximately one in a thousand deliveries. Very few studies evaluated PAS risk factors based on their location. In this study, we have investigated the effects of placenta location on placental adhesion-related complications, its risk factors, and outcomes. Materials and methods: We performed a retrospective cohort study of pathology-confirmed cases of PAS from patients with peripartum hysterectomy, at a large educational hospital in Qazvin, Iran, from 2009 to 2019. Placenta location was found by ultrasound reports and intraoperative evaluation. We measured demographic features, basic characteristics, maternal and neonatal outcomes based on placental location including anterior, posterior, and lateral in Placenta Accreta Spectrum. Chi-square, t-test, and one-way ANOVA were used to examine the relation of complications, risk factors, and outcomes in PAS. Results: A review of 70 cases showed the distribution of placenta location as follows: 57% anterior, 27% posterior, and 16% lateral. The mean gestational age at delivery was 35 (33-39) weeks. In 78.6% (n=55) of the patients, an association with placenta previa and in 94/2% (n=66) of cases a history of cesarean section was found, however, it was not significantly correlated with placenta location (p=0.082). We found that surgery duration was significantly longer in patients with lateral PAS (155±38, vs 129.35±33.8 and 133.15±31.5 for anterior and posterior placenta respectively, p=0.09). Patients with lateral PAS also bled more than the remaining two groups (2836 ml for lateral PAS vs 2002 and 1847 for anterior and posterior placenta respectively, p=0.022). Moreover, women with a history of uterine surgery were more likely to have posterior PAS compared to those with anterior and lateral PAS (p=0.035). Conclusion: Differences in complications, risk factors, and outcomes of PAS based on placenta location may lead to improved diagnosis and decreased morbidity in women.

Objective The aim of this study was to examine the risk factors for antepartum hemorrhage (APH) in women with placenta previa. Methods In this retrospective cohort study, we analyzed the medical records of 233 women with singleton pregnancies presenting with placenta previa whose deliveries were performed at our hospital between January 2009 and July 2018. Results Of the 233 women included in this study, 130 (55.8%) had APH. In the APH group, the gestational age and neonatal birth weight were significantly lower compared with the no hemorrhage group. Maternal age <30 years and multiparity were identified as significant risk factors for APH in both the univariate and multivariate analyses. Focusing on the previous route of delivery in multiparous women, the risk of APH was significantly higher in multiparous women who had experienced at least one vaginal delivery compared with nulliparous women (adjusted odds ratio (OR): 3.42 [95% confidence interval: 1.83–6.38]). Conclusion We showed that women with placenta previa who were under 30 years old and who had a history of vaginal delivery may be at significant risk of experiencing APH.

Abstract Background: To examine differences in maternal characteristics and pregnancy outcomes among Chinese women with infertility due to various reasons who underwent assisted reproductive technology(ART). Methods: This retrospective cohort study included women who used ART for various reasons. Demographics, medical history, laboratory tests, and delivery data were reviewed. Results: The ART treatment group was divided into 5 subgroups according to reason for infertility: ovulation disorder, tubal disease, male factor, endometriosis, multiple infertility-related diagnoses. Compared with spontaneous pregnancies, significant increases in the following were observed with ART: rates of gestational diabetes mellitus(GDM), preeclampsia, preterm premature rupture of membranes, postpartum hemorrhage, and chorioamnionitis in ovulation disorder; GDM, placenta previa and postpartum hemorrhage in tubal disease; placenta previa in endometriosis and male factor; and GDM, placenta previa and chorioamnionitis in multiple infertility-related diagnoses. Preterm birth, low birthweight, and small for gestational age were increased in all ART groups. Macrosomia and neonatal intensive care unit admission were increased in maternal factors with ART. Conclusions: During the perinatal period, women with different reasons for undergoing ART have different maternal characteristics and infant outcomes when compared with women not using ART, perinatal morbidities are higher in women undergoing ART for most reasons. The worst and best prognoses for infertility were found for that caused by ovulation disorder and male factor, respectively.
