occipitofrontal diameter
1.Methods The fetal biparietal diameter (BPD) , occipitofrontal diameter (OFD), head circumference (HC), abdomen circumference (AC), abdomen transverse diameter (ATD), femur length (FL) were measured by ultrasonography on 414 pregnant woment wiht dilivery in hospital, single fetus, four days before childbirth. Every parameter was measured twice and averaged.
2.The right atrium diameter from left to right,occipitofrontal diameter of right ventricle,main pulmonary atery bore and pulmonary artery systolic pressure were also reduced after treatment than that before in both groups,but after treatment,occipitofrontal diameter of right ventricle,main pumonary artery bore of group R were significangtly higher than that of group F.
