Abstract

The application of first trimester volumetry in predicting pregnancy complications is a promising and interesting field in Obstetrics and Radiology. This was a descriptive review of first trimester volumetry in predicting pregnancy complications over a period of 6 months (January 1st, 2013 to June 30th, 2013). A search of literature on first trimester volumetry published in English was conducted. Relevant materials on first trimester volumetry were selected. Placenta volumes (PV) and embryo volume/fetal volume ratios in the first trimester are correlated with crown rump length (CRL) or gestational age (GA). Measurement of PV or placental quotient (PV/CRL ratio) is an early assessment to identify impaired trophoblast invasion and predict subsequent development of intrauterine growth restriction (IUGR) or pre‑eclampsia (PE). In early onset IUGR due to triploidy, or trisomy 13 or 18, a larger deficit in fetal volume is observed compared to CRL. In obstetric sonography, standardization of the 3D volumetric methodology is needed to improve reproducibility of measurement. The accuracy of these measurements is uncertain and current applicability to practice is not fully accepted, therefore, the current methods are yet to be standardized and general applicability is uncertain. Volumetry holds a good promise as an extra method for predicting IUGR, PE, aneuploidy, miscarriages, or stillbirth but lack of standardization currently limits its applicability.

孕早期容积法在预测妊娠并发症中的应用
应用孕早期体积法预测妊娠并发症是产科和放射学中一个有前途和有趣的领域。这是一项描述性的回顾,在6个月期间(2013年1月1日至2013年6月30日),早期妊娠容积法预测妊娠并发症。我们检索了有关孕早期体积测定的英文文献。选择有关孕早期体积测定的资料。妊娠早期胎盘体积(PV)和胚胎体积/胎儿体积比与冠臀长(CRL)或胎龄(GA)相关。测量PV或胎盘商(PV/CRL比率)是一种早期评估,可识别滋养细胞侵袭受损,并预测宫内生长受限(IUGR)或先兆子痫(PE)的后续发展。在由三倍体或13或18三体引起的早发性IUGR中,与CRL相比,观察到更大的胎儿体积缺陷。在产科超声检查中,需要标准化三维体积测量方法,以提高测量的可重复性。这些测量的准确性是不确定的,目前对实践的适用性并没有被完全接受,因此,目前的方法尚未标准化,普遍适用性不确定。体积法作为预测IUGR、PE、非整倍体、流产或死产的一种额外方法具有良好的前景,但目前缺乏标准化限制了其适用性。
