Placenta previa can be difficult to diagnose with transabdominal sonography during the third trimester of pregnancy, because of difficulties in imaging the cervix late in pregnancy. Although transperineal sonography offers an additional view of the cervix, its value in the diagnosis of placenta previa has not been studied. Accordingly, we performed transperineal sonography on 164 patients who h...

BACKGROUND Placenta previa is known to be associated with previous caesarean deliveries, advanced maternal age, increasing parity, smoking, curettage and myomectomy. This study was carried out to compare the frequency of placenta previa, in women with previous caesareans versus those with normal vaginal deliveries. METHODS It was one year study conducted at the Department of Obstetrics and Gy...

PURPOSE To evaluate whether type and location of placenta previa affect risk of antepartum hemorrhage-related preterm delivery. METHODS We retrospectively studied 162 women with singleton pregnancies presenting placenta previa. Through observation using transvaginal ultrasound the women were categorized into complete or incomplete placenta previa, and then assigned to anterior and posterior g...

Objective: To review the use of transvaginal ultrasound for the diagnosis of placenta previa and recommend management based on accurate placental localization. Options: Transvaginal sonography (TVS) versus transabdominal sonography for the diagnosis of placenta previa; route of delivery, based on placenta edge to internal cervical os distance; in-patient versus out-patient antenatal care; cercl...

BACKGROUND This study investigated whether fetuses of placenta previa pregnancies have cardiac dysfunction by use of a modified myocardial performance index (Mod-MPI). MATERIAL AND METHODS A prospective cross-sectional study was conducted including 178 fetuses at 28-40 weeks of gestation. Eighty-nine fetuses of mothers with placenta previa and without pregnancy complications were recruited (pla...

BACKGROUND Placenta previa is characterized by the abnormal placenta overlying the endocervical os, and it is known as one of the most feared adverse maternal and fetal-neonatal complications in obstetrics. OBJECTIVES We aimed to obtain overall and regional estimates of placenta previa prevalence among deliveries in Mainland China. METHODS The research was performed a systematic review, fol...

BACKGROUND The incidence of placenta previa has been increasing. It is of a great importance to determine the clinical risk factors for peripartum blood transfusion in women with placenta previa in an effort to anticipate cases of severe hemorrhage. METHODS A total of 129 consecutive cases of placenta previa (64 cases of complete placenta previa and 65 cases of marginal placenta previa), incl...

AIM To evaluate potential risk factors and perinatal outcome of pregnancies complicated with placenta previa in Croatian population of pregnant women recruited from the largest tertiary care perinatal center in Croatia. METHODS This retrospective case-control study included a total of 202 singleton pregnancies with placenta previa during a 10-year study period and 1,004 randomly selected simp...

OBJECTIVE To assess the role of ultrasound in detecting the migration of placenta previa during the third trimester at Lady Willingdon Hospital and Jinnah Hospital, Lahore during the period July 2000 to September 2002. METHODS Eighty pregnant women with the diagnosis of placenta previa at 28 to 32 weeks of gestation were included in the study. After base line ultrasound, scan was repeated eve...

OBJECTIVES Placenta previa is a major cause of neonatal anemia. The purpose of this study was to elucidate the risk factors of neonatal anemia in placenta previa. METHODS The study was conducted on 158 placenta previa patients at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 through December 2009. The subjects were divided in to 2 groups: 47 placenta ...
