INTRODUCTION: Ogilvie's Syndrome or Acute Colonic Pseudo-Obstruction (ACPO) is a rare condition characterized by massive dilatation of the colon in the absence of mechanical obstruction. About 10% of all reported cases are related to Obstetric and Gynaecological procedures, Caesarean section being the commonest associated factor. Acute intestinal dilatation, if not treated, may lead to perforation and faecal peritonitis with consequent high morbidity and mortality. MATERIALS AND METHODS: An electronic literature searches were performed in PubMed, EMBASE, Google scholar and hand searches for relevant references were included without any language restriction...

BACKGROUND: Approximately 1/3 of all deliveries in the United States are via cesarean. Previous research indicates weight gain during pregnancy is associated with an increased risk of cesarean delivery. It remains unclear, however, whether and to what degree weight gain between deliveries (i.e., inter-delivery weight gain) is associated with cesarean delivery in a subsequent pregnancy following a vaginal delivery. OBJECTIVES: To determine whether inter-delivery weight gain is associated with an increased risk of intrapartum cesarean delivery following a vaginal delivery...

Objective. To determine maternal morbidity in women with placenta previa managed with prediction of morbidly adherent placenta (MAP) by ultrasonography. Methods. A retrospective cohort study was undertaken comprising forty-one women who had placenta previa with or without risk factors for MAP. Women who had all three findings (bladder line interruption, placental lacunae, and absence of the retroplacental clear zone) were regarded as high suspicion for MAP and underwent cesarean section followed by hysterectomy...

BACKGROUND: Several epidemiological studies have determined that assisted reproductive techniques (ART) can increase the risk of placenta previa. To date, only a meta-analysis has been performed for assessing the relationship between placenta previa and ART. This meta-analysis was conducted to estimate the association between placenta previa and ART in singleton and twin pregnancies. METHODS: A literature search was performed in major databases PubMed, Web of Science, and Scopus from the earliest possible year to April 2017...

BACKGROUND: Incidental leiomyosarcoma (LMS) is a rare diagnosis in pregnancy or in the puerperium. To our knowledge, this is the first case reported in the literature of incidental LMS after cesarean hysterectomy for morbidly adherent placenta. CASE: We present a case of a cesarean hysterectomy performed for a suspected morbidly adherent placenta in a patient with three prior cesarean deliveries, an anterior placenta previa and a fundal fibroid. Subsequent pathology identified a LMS on final specimen...

For patients with placenta previa (PP) with a suspected abnormally invasive placenta (AIP), "the higher the 'concern' for preterm delivery and severity of AIP, the earlier the surgery date" may be better. Perlman et al. (1) showed that "scheduled surgery" at ≥36 weeks was possible for many patients. The incidence of massive bleeding did not differ among 34, 35 vs. ≥36 weeks. They concluded "patients with 'no concern' for percreta/increta or no prior cesarean section (and no preterm-delivery risk) may be candidates for later delivery"...

Abnormally invasive placentation is becoming more common with a recent increase in cesarean sections and maternal age, among other risk factors. Ultrasonography is the first line-imaging, but it can be difficult to diagnose when limiting factors are present. Failure to recognize this serious placental abnormality precludes us from making the appropriate plan for the delivery and consequently can lead to fatal results. In this report, we present a case in which magnetic resonance imaging was used to diagnose posterior placenta increta missed by multiple sonographic examinations in a patient with previous myomectomies, and we also include a review of the literature on this topic...

REVIEW

The anomalies in placental insertion and invasion, such as placenta previa and the various forms of abnormally invasive placenta, are today a rising obstetric pathology. Two-dimensional (2D) ultrasonography is the gold standard in the diagnosis of abnormally invasive placenta (AIP), but the important feto-maternal impact of this pathology suggests the opportunity to employ all the available diagnostic techniques, such as three-dimensional (3D) power Doppler. This technique allows acquiring multiplanar images on coronal, axial and sagittal planes and with a rotational technique, it permits visualizing the placenta-bladder interface more accurately...

The frequency of cesarean hysterectomy is increasing, predominantly driven by an increased incidence of morbidly adherent placenta (MAP) associated with prior cesarean section with or without placenta previa. Most cases of MAP are located anteriorly with involvement of the bladder. The lower uterine segment in increta and percreta cases is frequently thinned and deformed, with extensive vascular supply to the bulging placenta. This deformation of the lower segment makes identification of the cervico-vaginal interface and vaginal fornices difficult...

OBJECTIVE: To evaluate the value of shear wave elastography (SWE) in the prediction of morbidly adherent placenta. METHODS: Forty-three women with normal placental location and 26 women with anteriorly localized placenta previa were recruited for this case-control study. Placental elasticity values in both the groups were determined by SWE imaging. RESULTS: SWE values were higher in the placenta previa group in all regions than in normal localized placentas (p < ...

Placenta previa accreta (PPA) can result in severe obstetric hemorrhage, which usually necessitates hysterectomy. The median blood loss for placenta accreta has been reported to range from 2000 to 7800 mL [1]. It is a severe and life-threatening obstetric complication in most countries. The present article reports a conservative, simple method-the two-tourniquet sequential blocking technique-to control severe bleeding during cesarean delivery in the event of PPA.

PURPOSE: It is important to predict massive postpartum hemorrhage in patients with placenta previa totalis (PPT) and a method that accurately predicts this event is needed. The present study developed a scoring system that predicts massive transfusion in patients with PPT. METHODS: This single-center retrospective cohort study comprised 238 patients with PPT who underwent caesarean section between January 2004 and December 2010. Massive transfusion was defined as the transfusion of ≥8 units of packed red blood cells within 24 h after delivery...
