Placenta previa: A 22-year analysis

Clinical study of placenta previa and its effect on maternal health and fetal outcome

“…Prior cesarean delivery increases the likelihood of placenta previa. 4 Incidence increases from 1.9% with 2 prior cesareans to 4.1% with 3 or more. 5 The simplest, most precise and safest method of placental localization is provided by transabdominal sonography.…”

A prospective study of maternal outcome in antepartum haemorrhage in tertiary care center in northern India

“…1 Depending on the definition used, antepartum haemorrhage complicated 2-5% of all pregnancies. [2][3][4][5] Placenta previa complicate 0.33 percent 6 to 0.55 percent 7 of all pregnancies and incidence of placental abruption incidence is approximately 0.5 to 1 percent. 8 Though maternal mortality due to antepartum haemorrhage has significantly dropped in developed countries with the introduction of improved medical facilities, in developing countries, it most important cause of maternal mortility and morbidity.…”

Risk factors of placenta previa: a population based study and the review of the literature

“…In literature, the prevalence of placenta previa has been reported as 0.3%-0.8% [5][6][7]. In recent years, several studies have reported an increase in the prevalence of placenta previa.…”

“…In recent years, several studies have reported an increase in the prevalence of placenta previa. This increase has been thought to be related to the enhanced trend for caesarean deliveries and the possibilities for easier diagnosis of placenta previa by improved imaging modalities [7][8][9].…”

“…The incidence of placenta previa and complicated pregnancy varies according to the population and has been reported as approximately 0.3%-0.8% [5][6][7]. While the etiology of placenta previa has not been fully clarified, related risk factors are known to be a history of caesarean section, advanced maternal age, multiparity, history of abortion, cigarette smoking and male gender fetus [5,6].…”
