Isolated fetal ascites: Etiology and prognosis – A 10-Year experience from a tertiary referral care center in India

Abstract

Introduction: Isolated fetal ascites is an uncommon finding, and it may be difficult to elucidate the underlying pathology. This is more so when there are limited resources to investigate the patient adequately. This study was undertaken to see the etiology of isolated fetal ascites and analyze the outcomes. Materials and Methods: Twenty-three cases of isolated fetal ascites were retrospectively analyzed from December 2007 to June 2018. All cases were investigated with detailed ultrasound with other investigations as required. Postnatal data included gestational age at birth, mode of delivery, weight, and postnatal outcome. Results: The mean age at diagnosis was 26 gestational weeks. Structural abnormalities without any underlying chromosomal or genetic cause were identified in 10/23 (43.4%) cases with the most common structural abnormality related to the gastrointestinal tract where ultrasound proved to the most useful tool. The overall good prognosis was seen in 13/23 (56.5%) cases. Conclusion: Appropriate perinatal care, timely referral and delivery at tertiary care setup, and timely surgical intervention are measures which can improve the outcome and survival in fetuses diagnosed with isolated fetal ascites.
