We report on 2 fetuses with congenital diaphragmatic hernia (CDH) in whom the fetal lung volumes were estimated by three-dimensional ultrasound and the results compared with the postmortem lung volume measurements. Both examiners (sonographer and pathologist) were blinded to each other's results. The 1st case was a right CDH diagnosed at 20 weeks of gestation. The 2nd case was a left CDH diagnosed at 22 weeks of gestation. Both pregnancies were terminated upon request of the parents. Three-dimensional ultrasound estimation of the fetal lung volume was performed 1 day before termination of pregnancy using the technique of rotation of the three perpendicular planes. The left and right lung volumes estimated by three-dimensional ultrasound were 3.88 and 1.87 cm(3), respectively, in the 1st case and 0 and 5.52 cm(3), respectively, in the 2nd case. On postmortem examination, the left and right lung volumes were 3.0 and 2.2 cm(3), respectively, in case 1 and 1.1 and 5.6 cm(3), respectively, in case 2. This suggests that a three-dimensional estimation of pulmonary volumes may be correlated with postmortem findings in cases with CDH.
我们报告了2例先天性膈疝（CDH）胎儿，通过三维超声估计胎儿肺容积，并将结果与尸检时的肺容积测量值进行比较。两位检查者（超声检查医师和病理学家）均对彼此的结果不知情。第1例为妊娠20周时诊断出的右侧CDH。第2例为妊娠22周时诊断出的左侧CDH。经父母要求，两例妊娠均终止。在终止妊娠前1天，采用三个垂直平面旋转技术进行胎儿肺容积的三维超声估计。在第1例中，三维超声估计的左肺和右肺容积分别为3.88和1.87 cm³，在第2例中分别为0和5.52 cm³。尸检时，第1例的左肺和右肺容积分别为3.0和2.2 cm³，第2例分别为1.1和5.6 cm³。这表明在CDH病例中，肺容积的三维估计可能与尸检结果相关。
