[Echographic morphometry of the fetal septum pellucidum in term pregnancy and in cases of congenital malformations].
The echographic morphometry of the fetal cerebral cranium includes a series of measurements and structural evaluation of the most important anatomical formation of the central nervous system (cns). Echographic anatomical relations of septum pellucidum were studied antenatally in 43 physiologically progressing pregnancies at term as well as in 13 pregnancies with congenital malformations of the fetus during the second and third trimester. It was established that at term pregnancy the transverse measurement of septum pellucidum reached values, forming 8.28-8.93% of the value of the fetal biparietal diameter. Its morphological examination proved that it has rectangular form during scanning of the fetal cranium at the level of "thalamus", interrupting the middle echo of the dividing line between the I and II thirds. In the group of pregnancies with malformations this structure was not discovered in neither case with congenital anomaly of cns as well as in cases with multiple malformative syndromes, involving intracranial content. The role of this parameter in early prenatal diagnosis of malformative fetopathies is discussed.
