Fetal anasarca

Radswiki et al.

Fetal anasarca refers to generalized fetal body edema and usually occurs as a component of hydrops fetalis. The fetal subcutaneous tissues appear diffusely thickened often to more than 5 mm. 


It occurs from a fluid shift from the intra-vascular compartment into the interstitial extra-vascular compartment as a result of impaired lymphatic drainage, capillary permeability and/or capillary hydrostatic/oncotic pressures.
