目标
确定先天性膈疝胎儿的腹围超声测量值是否较小，以及这是否反映为低估了估计的胎儿体重。
研究设计
对 85 名先天性膈疝胎儿在妊娠 24 至 41 周期间进行的 225 次腹围测量进行了回顾性审查。绘制妊娠周的个体腹围值和平均腹围值与胎龄的关系图，并与标准数据进行比较。通过 chi(2) 检验对腹围测量值和疝气变量进行比较。皮尔逊相关性用于检查超声测定估计胎儿体重的准确性。
结果
尽管患有肝疝的胎儿的腹围测量值低于平均值超过 2 个标准差的可能性较小，但直到足月，腹围的平均测量值并未发现与标准数据有显着差异。估计胎儿体重的计算准确度与正常胎儿相似。
结论
患有先天性膈疝的胎儿不应期望腹围测量值较小。在不考虑其他病因的情况下，腹围或腹围相关的估计胎儿体重的异常不应归因于解剖缺陷。
OBJECTIVE
To determine whether ultrasonographic measurements of the abdominal circumference are smaller in fetuses with congenital diaphragmatic hernia and whether this is reflected as an underestimation of the estimated fetal weight.
STUDY DESIGN
A retrospective review of 225 abdominal circumference measurements made between 24 and 41 weeks of gestation in 85 fetuses with congenital diaphragmatic hernia was performed. The individual and mean abdominal circumference value at each week of gestation versus gestational age was plotted and compared with normative data. Comparisons between abdominal circumference measurements and hernia variables were made with the chi(2) test. The Pearson correlation was used to examine the accuracy of ultrasonographic determination of the estimated fetal weight.
RESULTS
The mean measurements of abdominal circumference were not found to differ significantly from normative data until term, although fetuses with liver herniation were less likely to have measurements more than 2 standard deviations below the mean. Calculation of estimated fetal weight was similar in accuracy to that in normal fetuses.
CONCLUSION
Small abdominal circumference measurements should not be expected in fetuses with congenital diaphragmatic hernia. Abnormalities of the abdominal circumference or an abdominal circumference-dependent estimated fetal weight should not be attributed to the anatomic defect without considering other etiologies.
