Hydrops fetalis caused by a blood group antibody usually undetected in routine screening.

Atrial natriuretic factor in hydrops fetalis caused by Rh isoimmunisation.

Plasma concentrations of atrial natriuretic factor were determined by radioimmunoassay in 16 human fetuses of between 19 and 38 weeks' gestation. Fifteen fetuses had varying degrees of anaemia as a result of Rh isoimmunisation, and one fetus was normal. Eight fetuses had ultrasonographic evidence of severe hydrops fetalis and an additional three fetuses had mild hydrops. Severely hydropic fetus...

Non-immune hydrops fetalis

Aetiology of hydrops fetalis.

These 2 cases provide additional examples of HUS occurring in sibs after a long interval. The family resided in New York City, which is not considered as an endemic area for HUS, and the clinical course of the disease in both infants was almost identical, culminating in early death. The aetiology of HUS may indeed be multiple, and the genetic basis for a significant proportion of cases does not...

Non immune hydrops fetalis.

With the decline in the frequency of rhesus isoimmunisation, hydrops fetalis secondary to other factors is becoming increasingly recognised. We describe a case in association with chorioangioma of the placenta. The causes of non immune hydrops are reviewed and the problems of management discussed.
