Abstract

Nonimmune hydrops fetals is defined as generalized edema of the fetal soft tissue in utero and may be associated with effusion in the serous cavities without hematologic evidence of isoimmunization. The most common demonstrable causes are cardiac anomalies, followed by chromosomal disorders, congenital malformations, alpha-thalassemia, and the twin-twin transfu-sion syndrome. We have experienced a case of nonimmune hydrops fetalis in identical twin which caused by congenital mitral valve insufficiency and disappeared spontaneously at 35 wks. Now we report a case of nonimmune hydrops fetalis that slowly and spontaneously imp-roved without interventions with a brief review of related literatures.

Key Words: Nonimmune hydrops fetalis, Mitral valve insufficiency, Identical twin
