Case of decidual discharge from the nonpregnant uterine cavity of the bicorporeal uterus before onset of delivery.

J Obstet Gynaecol Res 2019 Apr 11. Epub 2019 Apr 11.

Perinatal Center for Maternity and Neonates, Yokohama City University Medical Center, Yokohama, Japan.

A 30-year-old woman with a bicorporeal uterus complained of abdominal pain and vaginal hemorrhage at 28 weeks and 5 days of gestation. There were no signs of placenta previa with echography in the second trimester; however, the echography showed a highly echoic area (91 × 85 mm), indicating placenta previa. Thereafter, abdominal pain and vaginal bleeding increased. Read More

The risk of adverse obstetric outcomes and the abnormal growth of offspring in women with a history of thyroid cancer.

Thyroid 2019 Apr 8. Epub 2019 Apr 8.

Northwestern University, Obstetrics and Gynecology , 303 E. Superior Street , Chicago, Illinois, United States , 60611 ;

Successful resuscitation of a patient with pernicious placenta previa and placenta accreta who had massive life-threatening bleeding during cesarean section: A case report.

Medicine (Baltimore) 2019 Apr;98(14):e15025

Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education.

Rationale: Pernicious placenta accrete (PPP) is an obstetrical complication associated with severe life-threatening hemorrhage, which is one of the leading causes of maternal mortality worldwide. Caesarean hysterectomy is the effective method to control intraoperative bleeding for this unscheduled high-risk patient. But a challenge for clinicians in this case is to determine the optimal timing of hysterectomy, because it will directly determine maternal outcome. Read More

Vaginal Bleeding in Late Pregnancy.

Emerg Med Clin North Am 2019 May 8;37(2):251-264. Epub 2019 Mar 8.

Department of Emergency Medicine, Virginia Tech Carilion School of Medicine, 1 Riverside Circle, 4th Floor Admin, Roanoke, VA 24016, USA.

Bleeding in late-term pregnancy can present as an innocuous start to parturition or a catastrophic maternal-fetal hemorrhage masked by the physiologic adaptations of pregnancy. The emergency management of late-term bleeding can be challenging, especially when providing stabilizing care in a limited-resource environment. Early recognition of life-threatening vaginal bleeding, potential causes, and emergency management of maternal-fetal distress is reviewed. Read More

Undiagnosed placenta praevia percreta: A rare case report and review of management.

Niger Postgrad Med J 2019 Jan-Mar;26(1):61-64

Department of Obstetrics and Gynecology, College of Medicine, University of Lagos, Lagos University Teaching Hospital, Idi-Araba, Lagos, Nigeria.

Placenta accreta spectrum disorders, especially placenta percreta (PP) and placenta praevia (PLP), are major risk factors for massive obstetric haemorrhage which is a common cause of maternal morbidity and mortality in our environment. This risk becomes exponential and life-threatening when the two conditions co-exist in the same patient. Even in advanced countries with readily available expertise and state of the art resuscitative and supportive facilities, these conditions are associated with grave maternal and perinatal morbidity and mortality.

Association of Overt and Subclinical Hyperthyroidism During Weeks 4-8 with Adverse Pregnancy Outcomes.

J Womens Health (Larchmt) 2019 Mar 11. Epub 2019 Mar 11.

1 Department of Endocrinology and Metabolism, Institute of Endocrinology, Liaoning Provincial Key Laboratory of Endocrine Diseases, The First Affiliated Hospital of China Medical University, Shenyang, P.R. China.

Background: Although increasing data suggest that hyperthyroidism is associated with adverse pregnancy outcomes, there are only a few reports with different conclusions on whether the mild transient reduction in thyrotropin (TSH) with or without free thyroxine (FT4) elevation during the early stage of pregnancy also causes adverse pregnancy outcomes.

Subjects And Methods: We analyzed data from 3,783 women in this study from August 2011 to December 2013. Participants completed a questionnaire survey. Read More

Proposal for ultrasound staging of placenta accreta spectrum disorders.

Ultrasound Obstet Gynecol 2019 Mar 4. Epub 2019 Mar 4.

Department of Clinical Medicine, Faculty of Health Sciences, UiT-The Arctic University of Norway, Tromsø, Norway.

Objective: To develop an ultrasound (US) staging system for placenta accreta spectrum disorders (PAS) and to ascertain whether it may stratify the risk of surgical outcome before birth.

Methods: Secondary retrospective analysis of a prospective collected data on women with placenta previa. We propose the following classification of PAS based upon the distribution of the different ultrasound signs in women with placenta previa: PAS0: Placenta previa with no US signs of invasion or placenta previa with placental lacunae but no evidence of abnormal uterine-bladder interface PAS1: Presence of at least two ultrasound signs among: placental lacunae, loss of the clear zone or bladder wall interruption.

Department of Obstetric and Gynecologic, West China Second University Hospital, Sichuan University, Sichuan, China.

Placenta previa accreta is an obstetrical complication that severely affects the heath of the fetus and the mother due to massive hemorrhage during pregnancy. This study reported a new suture technique called "cervical internal os plasty" to control obstetrical hemorrhage in cesarean delivery for patients with placenta previa accreta and retrospectively evaluated the safety and effectiveness of the new technique.From January 2012 to May 2018, we collected 56 patients with this new suture technique, which repaired the damaged weak area with bleeding from the placental attachment site in the lower uterine segment, and restored the damaged anatomic internal os of the cervix.

Is there any role for fetoscopic laser ablation therapy in type-2 vasa previa?

Ultrasound Obstet Gynecol 2019 Feb 24. Epub 2019 Feb 24.

Maternal-Fetal Medicine Division, Department of Obstetrics and Gynecology, Mayo Clinic College of Medicine, Rochester, Minnesota, United States.

Here we reviewed the literature regarding an interesting new approach to treat type 2 vasa previa (VP). Vasa previa is a rare placental disorder in which fetal blood vessels, unsupported by underlying placenta, cross over the cervical internal os; type 1 vasa previa is attributed to a velamentous cord insertion near the cervix while type 2 vasa previa occurs when connecting vessels of a bi or multilobed placenta cross over internal cervical . To date, there have been 5 reported cases of fetoscopic laser ablation for the treatment of type 2 vasa previa between 22 and 33 weeks' gestation . Read More

Complications and adverse outcomes in pregnancy and childbirth among women who conceived by assisted reproductive technologies: a nationwide birth cohort study of Japan environment and children's study.

BMC Pregnancy Childbirth 2019 Feb 20;19(1):77. Epub 2019 Feb 20.

Medical Support Center for Japan Environment and Children's Study (JECS), National Center for Child Health and Development, 2-10-1 Okura, Setagaya-ku, Tokyo, 157-8535, Japan.

Background: Although pregnancies conceived by assisted reproductive technology (ART) have a higher risk of maternal/perinatal complications, the overall risk of adverse outcomes necessitating advanced obstetric care has not been closely examined. The present study aimed to assess and compare the risk of maternal/perinatal complications and adverse outcomes in pregnancy and childbirth conceived by ART with those conceived naturally.

Rationale: It is very difficult to treat patients with placenta previa who underwent pregnancy termination and suffered antenatal massive hemorrhage in the 2nd trimester.

Patient Concerns: In this study, case 1 was with fetal malformation of 18-trisomy syndrome at gestation of 19 weeks + 2 days, case 2 was with fetal malformation of 18-trisomy syndrome at gestation of 22 weeks + 1 day, and case 3 was for intrauterine fetal death at gestation of 27 weeks. All the 3 cases were completely placenta previa. Read More
