We sought to evaluate the extent of the association between placental implantation abnormalities (PIA) and preterm delivery in singleton gestations. We conducted a systematic review of English-language articles published from 1980 onward using PubMed, MEDLINE, EMBASE, CINAHL, LILACS, and Google Scholar, and by identifying studies cited in the references of published articles. Search terms were PIA defined as ≥ 1 of the following: placenta previa, placenta accreta, vasa previa, and velamentous cord insertion. Observational and experimental studies were included for review if data were available regarding any of the aforementioned PIA and regarding gestational age at delivery or preterm delivery. Case reports and case series were excluded. Studies were reviewed and data extracted. The primary outcome was gestational age at delivery or preterm delivery<37 weeks' gestation. Secondary outcomes included birthweight, 1- and 5-minute Apgar scores, neonatal intensive care unit (NICU) admission, neonatal and perinatal death, and small for gestational age. Of the 1421 studies identified, 79 met the defined criteria; 56 studies were descriptive and 23 were comparative. Based on the descriptive studies, the preterm delivery rates for low-lying/marginal placenta, placenta previa, placenta accreta, vasa previa, and velamentous cord insertion were 26.9%, 43.5%, 57.7%, 81.9%, and 37.5%, respectively. Based on the comparative studies using controls, there was decreased pregnancy duration for every PIA; more specifically, there was an increased risk for preterm delivery in patients with placenta previa (risk ratio [RR], 5.32; 95% confidence interval [CI], 4.39-6.45), vasa previa (RR, 3.36; 95% CI, 2.76-4.09), and velamentous cord insertion (RR, 1.95; 95% CI, 1.67-2.28). Risks of NICU admissions (RR, 4.09; 95% CI, 2.80-5.97), neonatal death (RR, 5.44; 95% CI, 3.03-9.78), and perinatal death (RR, 3.01; 95% CI, 1.41-6.43) were higher with placenta previa. Perinatal risks were also higher in patients with vasa previa (perinatal death rate RR, 4.52; 95% CI, 2.77-7.39) and velamentous cord insertion (NICU admissions [RR, 1.76; 95% CI, 1.68-1.84], small for gestational age [RR, 1.69; 95% CI, 1.56-1.82], and perinatal death [RR, 2.15; 95% CI, 1.84-2.52]). In singleton gestations, there is a strong association between PIA and preterm delivery resulting in significant perinatal morbidity and mortality.

“…About 80% of cases are placenta accreta vera, 15% increta, and 5% percreta (1). Placenta accreta not only can lead to life-threatening intrapartum and postpartum hemorrhage, but also poses a serious risk to the developing fetus, with a 12-fold increase in preterm delivery and a 5-fold increase in small for gestational age births (2). A history of more than one prior cesarean section and placenta previa increase the risk of placenta accreta (3).…”

The etiology of postpartum hemorrhage (PPH) is diverse and management depends on identifying the cause and tailoring treatment appropriately. The major causes of PPH are uterine atony, endometritis, retained placental tissue, placental abnormalities, i.e. placenta accreta, increta and percreta, sub in volution of the placental implantation site, arteriovenous malfor mation (AVM), lower genital tract trauma, uterine abnor malities, bleeding disorders, coagulopathies and use of anticoagulants. Use of imaging modalities (i.e. ultrasound scanning and color and pulsed Doppler) at an early stage in the search for the etiology of PPH helps to decrease morbidity and mortality.This article reviews the differential diagnoses for bleeding in the postpartum period and assesses the role of ultrasound in the diagnosis and treatment of postpartum bleeding. By using illustrative images, the reader will be able to correlate findings on Bmode, color Doppler and 3D ultrasound in diagnosis and treatment of postpartum bleeding. It is important to be aware of the appearance of normal postpartum uterus to avoid misdiagnosis.

Perinatal Outcome of Pregnancies Complicated by Placenta Accreta

Abstract: Pregnancies complicated by placenta accreta are at increased risk for perinatal adverse outcome. We speculate that these findings may arise from pathological implantation of the placenta, resulting in interference with normal fetal growth.
