The ultrasonograms of 15 patients with moderate to marked fetal hydrocephalus were evaluated retrospectively in an attempt to determine the effect of ventricular dilatation upon biometry of the fetal head in the latter half of pregnancy. In 13 of the 15 cases the age based upon biometry of the fetal head was within one week of the clinical estimate of gestational age based upon the last menstrual period. As accurate head measurements may be useful even in cases of hydrocephalus, these measurements should not be dismissed as being invalid particularly when commensurate with a clinical estimate of gestational age.
回顾性评估了15例中度至重度胎儿脑积水患者的超声检查结果，以确定妊娠后半期脑室扩张对胎儿头部生物测量的影响。在15例中的13例中，根据胎儿头部生物测量得出的孕周与根据末次月经推算的临床孕周估计值相差在一周之内。即使在脑积水病例中，准确的头部测量也可能有用，这些测量结果不应被视为无效而不予考虑，尤其是当它们与临床孕周估计值相符时。
