The condition occurs when a. For non-immune hydrops treatment is based on the cause of the hydrops. Non-immune hydrops can develop in pregnancies where the fetus has an underlying genetic disease or when a viral infection occurs.

NIHF can result from many various underlying conditions such as. Its caused by a genetic disorder or congenital disability that interferes with the babys. Hydrops fetalis refers to abnormal fluid collections in at least two fetal serous cavities eg ascites pleural effusions andor pericardial effusions often associated with skin edema. Nonimmune hydrops fetalis NIHF comprises the subgroup of cases not caused by red cell alloimmunization.
