The incidence of immune-mediated hydrops, however, has markedly decreased since the implementation of antenatal immune globulin prophylaxis . It occurs when another condition or disease interferes with the baby’s ability … Here is to report on a ca… Specifically, non-immune hydrops fetalis 3. Non-immune hydrops fetalis (NIHF). Patients without hydrops fetalis, or patients of acquired chylothorax (post-operative or traumatic chylothorax), of non-idiopathic chylothorax (with an identifiable cause, such as chromosomal anomalies, structural heart defects, immune mediated diseases, severe anemia, or evidence of viral infection) were excluded. To search for an efficient method of management of non‐immune hydrops fetalis (NIHF), the clinical outcome of 51 newborns with NIHF was retrospectively assessed in a single centre. Hydrops fetalis (HF) consists of an abnormal accumulation of fluid in two or more fetal compartments, including ascites, pleural effusion, pericardial effusion, and skin edema. In some patients, it also may be associated with polyhydramnios and placental edema. 1 HF may be attributable to immune or nonimmune causes. Hydrops fetalis (HF) is a serious fetal condition defined as an abnormal fluid accumulation in fetal extravascular compartments and body cavities caused by either immune or non immune conditions.

It occurs when an underlying disease, genetic disorder or birth defect interferes with the ability of the baby’s body to manage fluid. Although most hydrops fetalis cases were historically caused by Rhe-sus isoimmunization, the etiology has shifted to predominantly non-immune causes after the implementation of Rhesus (D) immune globulin.1,2 The presence of nonimmune hydrops fetalis (NIHF) generally portends a poor prognosis, with substantial risks of intrau- One is immune in nature, and results from blood type incompatibility between the pregnant woman and fetus.

As the short‐term outcome, the mortality rate was mainly dependent on the causes of NIHF and the presence of pleural effusion. RESULTS: Non-immune hydrops accounted for 80% of the cases and the majority of babies required Level 1 intensive care. Identify patients appropriate for referral for prenatal exome sequencing with an indication of nonimmune hydrops fetalis. Despite proper diagnoses and therapies, mortality rates for affected fetuses and newborns are still considerable [].The persistence of the underlying cause beyond the fetal … A chromosomal abnormality was detected in 10% of the fetuses with non-immune hydrops. 1. These guidelines educate readers about the causes of non-immune fetal hydrops and its prenatal counselling and management. Hydrops fetalis is severe swelling (edema) in an unborn baby or a newborn baby. Most of these babies now have non-immune hydrops and approximately two thirds are surviving. 28.
