超声检查已广泛应用于单胎胎儿生长发育的评价。然而，双胞胎妊娠却没有受到那么仔细的关注。对103例双胎妊娠的双顶径（BPD）、股骨长（FFL）和腹围（AC）的生长模式与单胎妊娠进行了比较。研究结果显示，相对于单胎，妊娠31至32周后双胎BPD生长下降。双胎AC生长率下降后，32-33周的妊娠相对于单胎，但双胎FFL生长模式并没有偏离单胎整个妊娠。由于双胞胎和单胞胎的BPD和AC的生长模式存在显著差异，因此提出了双胞胎BPD和AC的新生长图。
Sonography has been used widely in the evaluation of singleton fetal growth. Twin gestations, however, have received less careful attention. In a statistical study of 103 twin pregnancies, the growth patterns of twin biparietal diameter (BPD), fetal femur length (FFL), and abdominal circumference (AC) were compared with those of singletons. The results of the study revealed a decrease in twin BPD growth after 31 to 32 weeks of gestation relative to singletons. Twin AC growth rate decreases after 32-33 weeks of gestation relative to singletons, but the twin FFL growth pattern does not deviate from that of singletons throughout gestation. Because of the significant difference in growth patterns of BPD and AC between twins and singletons in our population, new growth charts for twin BPD and AC are proposed.
