title: Sonographic measurements of the fetal spleen: clinical implications.
abstract: Normal values for fetal spleen dimensions are proposed, including longitudinal, coronal, and transverse diameters, the perimeter, and the estimated volume. Similar values were then obtained in cases of Rh-immunization and prolonged premature rupture of the membranes. A good correlation between amniotic fluid optical density and fetal spleen size was found. Only severely affected fetuses showed splenic values above the upper limit. Since sonographic examination can be regarded as a reliable method, nomograms can be useful in detecting growth disorders of the fetal spleen and thus provide a new complementary method to identify possible fetal diseases of genetic disorders.
