INTRODUCTION We aimed to study the profile of nonimmune hydrops fetalis (NIHF) in the local population and identify its outcomes and causes.
METHODS We carried out a retrospective review of the medical records in KK Women’s and Children’s hospital, a single tertiary referral centre, for pregnancies with an antenatal diagnosis of NIHF in the six-year period from 1 January 2005 to 31 December 2010.
RESULTS A total of 29 cases of NIHF were identified; 19 (66%) cases underwent karyotype evaluation, 17 (59%) underwent intrauterine infection screening, and all underwent antenatal thalassaemia screening. The median gestational age at diagnosis was 27 (range 12–37) weeks, median gestational age at birth was 33 (range 27–37) weeks, and median birth weight of live births was 2,480 (range 1,230–3,900) g. The aetiologies for NIHF were identified in 20 (69%) cases, which included cardiac anomalies (n = 5), haematological problems (n = 4), congenital tumours (n = 4), genetic/metabolic disorders (n = 4) and cystic hygromas (n = 3). The cause of NIHF was not identified in the remaining 9 (31%) cases. There were 19 live births – 8 (42%) survived and 11 (58%) died in the neonatal period – and one stillbirth. Nine women opted for medical termination of pregnancy following the diagnosis of NIHF.
CONCLUSION It is important to thoroughly investigate all cases of NIHF and identify its causes in order to provide appropriate antenatal and postnatal counselling. In our series, almost one-third of NIHF cases had no identified aetiology. The neonatal mortality rate was approximately 58%.
