The fetal superior cerebellar vermian width in normal, growth-restricted and macrosomic fetuses.

Abstract

Objectives : To obtain dimensions of the fetal superior cerebellar vermian width as a basis for further studies and for comparisons with deviation in growth. Study design : The study group included 266 normal pregnant women from 20 to 37 weeks of gestation. Several biometric measurements were obtained throughout pregnancy, including the fetal superior cerebellar vermian width. Forty-three growth-restricted and 30 macrosomic fetuses were included in this study. Results : A linear growth function was observed between the superior cerebellar vermian width and gestational age (GA) ( R = 0.859; p < 0.00001; y = -4.033 + 0.416 2 GA), transverse cerebellar diameter (TCD) ( R = 0.870; p < 0.00001; y = 0.404 + 0.223 2 TCD), biparietal diameter (BPD) ( R = 0.823; p < 0.00001; y = -3.086 + 0.155 2 BPD), head circumference (HC) ( R = 0.82; p < 0.00001; y = -3.21 + 0.434 2 HC), femoral length (FL) ( R = 0.843; p < 0.00001; y = -1.75 + 0.184 2 FL) and humeral length (HL) ( R = 0.824; p < 0.00001; y = -2....
