Oligohydramnios, intrauterine growth retardation and fetal death due to umbilical cord torsion
Carnegie South Carnegie Hill Carnegie South. Carnegie Hill. Intrauterine fetal death IUFD is a concern in high-risk pregnancies. Although there are some known causes and risk factors, many cases of second trimester IUFD do not present classically and a clear cause of IUFD is not always found. Fetal death in utero, commonly known as stillbirth, is categorized based on how far along it occurs during pregnancy. Second trimester intrauterine fetal death is typically recognized as a demise after 20 weeks of gestation and a fetal weight of more than grams.
Causes and Risk of Stillbirth
Intrauterine fetal demise is the clinical term for stillbirth used to describe the death of a baby in the uterus. The term is usually applied to losses at or after the 20th week of gestation. Pregnancies that are lost earlier are considered miscarriages and are treated differently by medical examiners. Parents of a stillborn baby, for example, will receive a birth and death certificate while those of a miscarried fetus will not. To many who have experienced such loss, the line between a stillbirth and miscarriage can often seem arbitrary but should in no way suggest that a parent’s emotional response is any more or less profound.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Women presenting to Washington Hospital Center with fetal loss would be offered participation in the study. The objective is to determine if ccffDNA obtained from maternal blood is present in the setting of missed abortion or fetal demise. The investigators primary hypothesis is that cell free fetal DNA will be present in maternal blood in the presence of a failed pregnancy.
Plasma will be retained for analysis of circulating cell free fetal DNA. Talk with your doctor and family members or friends about deciding to join a study.
Medical treatment for early fetal death (less than 24 weeks).
Learn more about stillbirth below. A stillbirth is the death or loss of a baby before or during delivery. Both miscarriage and stillbirth describe pregnancy loss, but they differ according to when the loss occurs. In the United States, a miscarriage is usually defined as loss of a baby before the 20th week of pregnancy, and a stillbirth is loss of a baby after 20 weeks of pregnancy.
Stillbirth affects about 1 in births, and each year about 24, babies are stillborn in the United States. Because of advances in medical technology over the last 30 years, prenatal care medical care during pregnancy has improved, which has dramatically reduced the number of late and term stillbirth.

Metrics details. Worldwide approximately 2. In the great part these deaths are inexplicable. The evenness and standardisation of the diagnostic criteria are prerequisites to understand their pathogenesis. The proposed protocol is mainly focused on the anatomopathological examination of the autonomic nervous system and in particular of the brainstem where the main centers that control vital functions are located. Updated investigative guidelines for the examination of unexplained stillbirths, prevalently focused on the histological examination of the brainstem, where the main centers that are involved in monitoring the vital functions are located, are here presented.
A section of this protocol concerns the Immunohistochemical evaluation of specific functional markers such as the neuronal nuclear antigen, nicotinic acetylcholine receptors, serotonin, orexin, apoptosis and gliosis. The important role of risk factors, having regard in particular to maternal smoking and air pollution is also contemplated in these guidelines. These alterations were rarely detected in a group of control cases. We hope this protocol can be adopted in all the Institutions notably for the examination of unexplained fetal deaths, in order to make uniform investigations.
This will lead to identify a plausible explanation of the pathogenetic mechanism behind the unexplained fetal deaths and to design preventive strategies to decrease the incidence of these very distressing events for both parents and clinicians. Peer Review reports. Fetal deaths, particularly at or near term, are the most common adverse pregnancy outcomes and the leading contributor to perinatal mortality.

Complete abortion A sub-category of miscarriage spontaneous abortion in which the non-viable pregnancy tissue has completely passed from the uterus, typically without medications or surgical intervention AAFP. A rarely used procedure whereby an abortion is completed by dilating the cervix and extracting the intact fetus from the uterus.

the risk factors of Intra Uterine Fetal Death (IUFD) and thereby prevent, control and treat Date of Submission: Date of Acceptance:
An intrauterine fetal demise IUFD , or stillbirth, is defined as a death that occurs in utero or during delivery after the completion of the 20th week of pregnancy or the death of a fetus that weighs g or more in utero or during delivery. Labor and delivery of the dead fetus usually occur spontaneously within 2 weeks. Patients are under tremendous psychological stress and are at a higher risk for postpartum depression.
Disseminated intravascular coagulation DIC is the main complication that can result. Thromboplastin released from the dead fetus is thought to mediate DIC. New research is suggesting that IUFD may also be caused by various perinatal infections, and some case reports have included positive fetal cultures for Erythrovirus B19, Haemophilus influenzae , hepatitis E, group B streptococci, and even Rothia dentocariosa, a normal bacteria found in the oral cavity of humans.
Also, domestic violence should be ruled out. Patients have the option of requesting an autopsy to determine the cause of death. If an autopsy is not performed, it may not be possible to determine the exact cause of fetal death. Genetic abnormalities are a significant cause of pregnancy loss including chromosomal abnormalities such as the trisomies see Spontaneous Abortion , p.

Stillbirth is typically defined as fetal death at or after 20 or 28 weeks of pregnancy , depending on the source. Often the cause is unknown. Worldwide prevention of most stillbirths is possible with improved health systems.
Stillbirth is typically defined as fetal death at or after 20 or 28 weeks of pregnancy, depending Fetal death in utero does not present an immediate health risk to the woman, and labour will usually begin of Ireland must be registered; stillbirths which occurred before that date can also be registered but evidence is required.
The United States Center for Health Statistics defines a fetal death as the delivery of a fetus showing no sign of life, as indicated by absent breathing, heartbeats, pulsation of the umbilical cord, or definite movements of voluntary muscles, irrespective of the duration of pregnancy. Currently, the most recognized definition of stillbirth is a fetal death that occurs at or greater than 20 weeks gestation or at a birth weight greater than or equal to grams.
Standardization of the definition of stillbirth is a current priority. An attempt is now underway to use stillbirth in all scientific publications. For this publication, intrauterine fetal demise and stillbirth are considered interchangeable. Comparison of stillbirth rates among and within countries is limited due to the non-uniformity of the definition of stillbirth and incomplete collection of stillbirth data.
Globally, less than 5 percent of stillbirths are recorded. There is currently a limited understanding of the pathophysiology responsible for fetal demise. This has been achieved already in many industrialized countries; however, countries in Asia and Africa still have much higher rates of stillbirth attributed mainly to lack of access to healthcare providers. Stillbirth has many causes: intrapartum complications, hypertension, diabetes, infection, congenital and genetic abnormalities, placental dysfunction, and pregnancy continuing beyond forty weeks.
This is a catastrophic event with lasting consequences on all of society. We need to learn more about why stillbirths occur. This knowledge can help those impacted deal with grief and, more importantly, prepare to reduce the risk of stillbirth in subsequent pregnancies. This activity reviews the role of the healthcare team in evaluating, managing, and improving care for patients diagnosed with stillbirth.

Despite advances in healthcare, stillbirth rates remain relatively unchanged. We conducted a systematic review to quantify the risks of stillbirth and neonatal death at term from 37 weeks gestation according to gestational age. We searched the major electronic databases Medline, Embase, and Google Scholar January —October without language restrictions. We included cohort studies on term pregnancies that provided estimates of stillbirths or neonatal deaths by gestation week.
We estimated the additional weekly risk of stillbirth in term pregnancies that continued versus delivered at various gestational ages. We compared week-specific neonatal mortality rates by gestational age at delivery. Thirteen studies 15 million pregnancies, 17, stillbirths were included. All studies were from high-income countries. Four studies provided the risks of stillbirth in mothers of White and Black race, 2 in mothers of White and Asian race, 5 in mothers of White race only, and 2 in mothers of Black race only.
The prospective risk of stillbirth increased with gestational age from 0. Neonatal mortality increased when pregnancies continued beyond 41 weeks; the risk increased significantly for deliveries at 42 versus 41 weeks gestation RR 1.

The first trimester is defined as the first 13 weeks of pregnancy following the last normal menstrual period some authors refer to early pregnancy as weeks. It can be divided into a number of phases, each of which has typical clinical issues. These phases are:. For a more detailed look at the stages of the first trimester see: ultrasound findings in early pregnancy.

Intrautrine fetal death was observed in a woman at 35 gestational weeks shortly after she was admitted to hospital due to suspected placental insufficiency expressed by oligohydramnios and fetal growth retardation. The pathologic examination showed umbilical cord torsion and an organized thrombus at the site of the torsion. This findings could imply that both the fetal death and the placental insufficiency were the results of the cord torsion. This is a preview of subscription content, log in to check access.

To compare provider assessment of fetal maceration with death-to-delivery interval to evaluate the reliability of appearance as a proxy for time of death. Cohort chart abstraction was performed for all stillbirth deliveries at or above 28 weeks of gestation during a 1-year period in a teaching hospital in Ghana. Of stillborn infants, had adequate data for analysis. Provider description of fetal appearance may be an unreliable indicator for time since fetal death.
The findings have significant implications for stillbirth prevention and assessment. Stillbirth remains a severely understudied and grossly underreported problem in low-income countries [ 1 , 2 ]. Efforts to reduce unacceptably high stillbirth rates in low-income nations typically distinguish between deaths occurring prepartum before labor and those occurring intrapartum during labor [ 3 ].
Advocates have long assumed that fresh stillbirths occur shortly before delivery and so might be preventable based on changes in care, resources, education, or medical access [ 4 — 7 ]. A reliable method to identify the approximate time of death and the death-to-delivery interval is challenging to obtain in low-resource settings. In community studies, verbal autopsies utilize interviews with families to register out-of-hospital births and fetal deaths and recording the last time that the mother perceived fetal movement as a proxy for time of death [ 8 , 9 ].
In facility-based deliveries, death-to-delivery interval is generally based on fetal appearance, as assessed by the physician, nurse, or midwife at delivery.
