Fetal anasarca

Last revised by Dr Ammar Haouimi on 21 May 2020

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. 

Pathology

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