Chang-kun Zhu, Fei Wang, Yu-mei Zhou, Jun Ying, Dan-qing Chen
OBJECTIVE: To analyze the maternal outcomes of pregnant women with pernicious placenta previa (PPP). METHODS: Clinical data of 470 patients with placenta previa admitted in Women's Hospital Zhejiang University School of Medicine from August 2012 to August 2014 were collected and retrospectively analyzed. The patients were divided into pernicious group(n=101) and non-pernicious group(n=369) according to the history of cesarean section and location of placenta attached to the uterine...

OBJECTIVE: Placenta accreta is an increasingly prevalent and potentially dangerous complication of pregnancy. Although most studies on the subject have addressed the risk factors for the development of this condition, evidence on maternal and neonatal outcomes for these pregnancies is scarce. The objective of the present study is to compile current evidence with regard to risk factors as well as adverse outcomes associated with placenta accreta. METHODS: We conducted a complete literature review using PubMed, MEDLINE, Cochrane Database Reviews, UptoDate, DocGuide, as well as Google scholar and textbook literature for all articles on placenta accreta, and any one of the following keywords: "risk factors", "maternal outcomes", "neonatal outcomes", "morbidity", and "mortality"...

This prospective cohort study aims to clarify the role of preterm placental calcification in high-risk (i.e., hypertension, diabetes, placenta previa or severe anemia) pregnant women as a predictor of poor uteroplacental blood flow (absent or reverse end-diastolic velocity [AREDV]) and adverse pregnancy outcome. Monthly ultrasound was performed starting at 28 weeks' gestation to establish the diagnosis of Grade III placental calcification, with measurement of Doppler velocimetry in the umbilical vessels at 32 weeks' gestation...

The biology of placental and fetal development suggests that alcohol may play a significant role in increasing the risk of feto-infant morbidity and mortality, but study results are inconsistent and the mechanism remains poorly defined. Previous studies have not examined the risk of placenta-associated syndromes (PASs: defined as the occurrence of either placental abruption, placenta previa, preeclampsia, small for gestational age, preterm, or stillbirth) as a unique entity. Therefore, we sought to examine the relationship between prenatal alcohol use and the risk of PAS among singleton births in the Missouri maternally linked data files covering the period 1989-2005...

Thyrotoxic crisis during pregnancy is a rare condition, but because of the danger it poses for the mother and fetus, every physician should be able to diagnose and treat it. When not recognized or incorrect treated hyperthyroidism, which is not easy to diagnose during pregnancy, is usually the basis for thyrotoxic storm. Serious conditions such as Graves' disease or multinodular goiter have to be distinguished from transient hyperthyroidism. Symptoms, such as: heat intolerance, hyperexia, emesis, tachycardia, increased pulse pressure and emotional liability should be considered cautiously because they are characteristic both for hyperthyroidism and for pregnancy...

Placenta accreta which occurs as a complication of total placenta previa is comparatively rare. And the diagnosis of placenta accreta before the caesarean section (C-section) is difficult. We experienced an extremely difficult anesthesia management of placenta accrete because of critical hemorrhage during C-section. We used self-blood collection device Cell Saver5+ (Haemonetics Japan Ltd, Tokyo) for the massive bleeding of 25,500 ml. The Cell Saver could be used to treat life threatening bleeding in C-section without any side effects, although it is thought that the use of the self-blood collection device during C-section had the danger of the amniotic fluid embolism and fetal red cell ontamination...

BACKGROUND: Vasa previa is a rare but potentially dangerous fetal condition that may occur during pregnancy. Ideally, all cases such cases are detected antenatally, but many present as late vaginal hemorrhaging. At the current time, there is no test for fetal hemoglobin (HbF) in general use. METHODS: A modified method of identifying HbF is presented. Five milliliters of 0.14 M NaOH was combined with 50 microl of a mixture of fetal and maternal blood. After 2 min, it was judged if the solution still had a red tone or not...

Venous thromboembolism is believed to be rare in Japan, whereas increases in occurrence of pulmonary embolism have been drawing attention because it has become the most common cause of maternal death in recent years. A 36-year-old woman at 33 weeks of pregnancy was transferred to our hospital because of placenta previa totalis and treated with emergency cesarean section on the same day. Soon after the delivery of the fetus, the patient developed pulmonary embolism. The condition of pulmonary embolism was suspected when abnormal values were noted in respiratory and circulatory parameters and then confirmed by intraoperative transesophageal echocardiography, which revealed a thrombus in the right atrium...

OBJECTIVE: To identify the risk factors associated with peripartum hysterectomy. STUDY DESIGN: The charts of 101 cesarean hysterectomies performed at Severance Hospital from January 1986 to April 2001 were reviewed. The patients were categorized into 2 groups. One was patients who underwent vaginal delivery followed by peripaRtum hysterectomy. The other was those who had cesarean section followed by peripartum hysterectomy. Paired t test and one-way ANOVA were used for statistical analysis...

Although peripartum cardiac arrest is rare, the prognosis of the event may be worse than in nonpregnant patients because the events is often associated with pulmonary or amniotic embolisms. The following report is a case of cardiac arrest which occurred at the induction of anesthesia for the postpartum hysterectomy. A 31-year-old woman was treated with infusion of ritodrine chloride for preterm labor and placenta previa. Elective cesarean section was performed at 37 weeks' gestation for her delivery under epidural anesthesia...

BACKGROUND: The aim of this research was to study the maternal and prenatal complications which may occur in the abruptio placentae and in placenta praevia. METHODS: All the patients who were hospitalized in the Obstetrics and Gynaecology Department of the Policlinico Umberto I, from January 1993 to July 2000 have been studied. Moreover, a comparative study between the onset of complications of the two pathologies considered and the ones found in a control group was carried out...

The increased rate of cesarean sections in recent decades has brought with it an increase in the frequency of placenta accreta. There are direct correlations between previous cesarean deliveries and also maternal age, with the risk of placenta accreta. There is also a direct correlation between placenta accreta and placenta previa. The risk of placenta accreta in women who have had placenta previa is 2% for those younger than 35 years and with no history of uterine surgery. The risk increases to 39% for those over 35 who have had 2 or more cesarean sections...

OBJECTIVE: We sought to compare obstetric and neonatal complications among great-grand multiparous, grand multiparous, and multiparous women. STUDY DESIGN: One hundred thirty-three great-grand multiparas, 314 grand multiparas, and 2195 multiparas who were delivered of their infants between 1988 and 1998 were selected for the study. To facilitate comparison, the patients were all >35 years old and had similar socioeconomic characteristics. RESULTS: The incidence of malpresentation at the time of delivery, maternal obesity, anemia, preterm delivery, and meconium-stained amniotic fluid increased with higher parity, whereas the rate of excessive weight gain and cesarean delivery decreased...

Two cases are presented illustrating the potential danger of abnormal placentation. Placenta accreta is frequently associated with placenta praevia and/or a history of previous caesarean section. As there are no obvious specific symptoms before or during delivery, one should consider the possibility of this anomaly in the third stage of labour when manual removal of the placenta is very arduous. The treatment of choice is immediate abdominal hysterectomy, for this is followed by the lowest maternal mortality...

There is a high association between anterior placenta previa, placenta accreta and previous cesarean section. We report three cases which illustrate the particular danger of massive hemorrhage posed by placenta previa/accreta in a scarred uterus. As the incidence of cesarean section continues to rise worldwide, the problem of placenta previa/accreta is likely to become more common. We emphasize the need for each obstetric unit to have a protocol for dealing with massive hemorrhage.

A resume of the main uses of echography in obstetrics and gynaecology in a private practice is presented. The procedure is a simple, atraumatic one, without danger of X-radiation to the fetus or the hazard of angiography to the patient, and can be repeated without risk. It has a high degree of accuracy, as well as being a very useful aid, to gynaecologists and general practitioners alike, whenever there is doubt in the clinical assessment, or for confirmation of any underlying complication.

The authors review their procedure adopted at ultrasonic placentography. Examinations were done before amniocentesis in 21 cases and because of supposed placenta praevia in 111 cases. Patients delivered at thier institution, so the site of placental implantation could be controlled. They had only one "dangerous" mistake: considering a placenta praevia to be only placental implantation on the lower segment, otherwise ultrasonic diagnosis was wrong in 5 cases. So the efficience of our method can be taken as 96,2 per cent...
