Placental abruption, classically defined as a premature separation of the placenta before delivery, is one of the leading causes of vaginal bleeding in the second half of pregnancy. Approximately 0.4–1% of pregnancies are complicated by placental abruption. The prevalence is lower in the Nordic countries (0.38–0.51%) compared with the USA (0.6–1.0%). Placental abruption is also one of the most important causes of maternal morbidity and perinatal mortality. Maternal risks include obstetric… 
Risk Factors and Maternal Complications of Placental Abruption in Third Trimester of Pregnancy
Frequency of hypovolemic shock is significantly higher followed by renal failure in females presenting with placental abruption during third trimester of pregnancy after 28 weeks of gestation, which can lead to substantial improvement in fetomaternal outcome in patients with placential abruption.
Epidemiology, Risk Factors, and Perinatal Outcomes of Placental Abruption—Detailed Annual Data and Clinical Perspectives from Polish Tertiary Center
Despite its rare occurrence, each center should develop a certain strategy for dealing with this pathology or predicting which patients are at risk, and much work is still needed to ensure the proper care of the mother and the baby in this life-threatening condition.
Placenta Abruption and Delivery Method
Placental abruption must be considered whenever bleeding is encountered in the second half of pregnancy, since it is a significant cause of third-trimester bleeding associated with fetal and maternal morbidity and mortality.
Does placental abruption cause neonatal anemia?
The hemoglobin levels of the neonates born after placental abruption are comparable to the reference curve and do not show more neonates than expected below the fifth percentile for gestational age, suggesting that at least a big amount of fetal blood is not lost, since the results suggest that a large number of anemic neonates do not need to be expected.
Feto Maternal Outcomes in Abruptio Placenta
Abruptio placenta continues to be responsible for increased maternal and fetal morbidity and is neither preventable nor predictable in majority of cases, so early detection and prompt management will reduce morbidity.
Study of Maternal and Foetal Outcome in Abruptio Placentae
It was concluded that abruptio placentae is still a leading cause of maternal morbidity and mortality that can be reduced with modern management of abruptio Placentae, but timely diagnosis and intervention is necessary.
Prevalence and Its Feto-Maternal Outcome in Placental Abruption: A Retrospective Study for 5 Years from Dubai Hospital
Having better equipped obstetric and neonatal units with multidisciplinary management can improve both maternal and perinatal outcome in cases of placental abruption.

Placental abruption and preterm premature rupture of membranes:How much frequent?
Clinicians should be cautious in follow up of patients after PPROM due to maternal and fetal morbidity andAbruptio placenta (AP) is not a rare complication after P PROM.


Placental abruption.
Most cases of placental abruption cannot be predicted or prevented, but in some cases, maternal and infant outcomes can be optimized through attention to the risks and benefits of conservative management, ongoing evaluation of fetal and maternal well-being, and through expeditious delivery where appropriate.
Placental abruption and perinatal mortality in the United States.
The link between fetal growth restriction and abruption suggests that the origins of abruption lie at least in midpregnancy and perhaps even earlier, and the high risk of perinatal death associated with abruption persisted.
Placental abruption and adverse perinatal outcomes.
In this cohort of singleton births between 1986 and 1996, placental abruption had a profound impact on stillbirth, preterm delivery, and fetal growth restriction.
Placental abruption and perinatal death.
The theory that, in cases of AP, a general impairment of the placenta and/or a defect placentation may be fatal is supported.
National Trends in the Incidence of Abruptio Placentae, 1979-1987
The rate of abruptio placentae increased significantly between the years 1979-1987 among women of all racial groups and most of the increase occurred among women likely to be financially and socially disadvantaged.
A history of placental dysfunction and risk of placental abruption.
The results suggest that pregnancy-induced hypertension, intrauterine growth retardation, preterm delivery and placental abruption share an aetiological factor or represent different clinical expressions of recurring placental dysfunction.
Evidence of placental abruption as a chronic process: associations with vaginal bleeding early in pregnancy and placental lesions.
Preterm Premature Rupture of Membranes, Intrauterine Infection, and Oligohydramnios: Risk Factors for Placental Abruption
Women presenting with preterm PROM are at increased risk of developing abruption, with the risk being higher either in the presence of intrauterine infections or oligohydramnios.
Reproductive risk factors, Doppler findings, and outcome of affected births in placental abruption: a population-based analysis.
Current antepartum methods of detecting uteroplacental problems, including Doppler ultrasonography, are not effective in prenatal prediction of placental abruption, and the outcome of affected births is still poor.
Prepregnancy risk factors for placental abruption
Although univariate analysis identified many risk factors, only smoking, uterine malformation, previous cesarean section, and history of placental abruption remained significant after multivariate analysis, increasing the risk of placmental abruption in subsequent pregnancy.
