Fetal growth restriction, also known as intrauterine growth restriction, is a common complication of pregnancy that has been associated with a variety of adverse perinatal outcomes. There is a lack of consensus regarding terminology, etiology, and diagnostic criteria for fetal growth restriction, with uncertainty surrounding the optimal management and timing of delivery for the growth-restricted fetus. An additional challenge is the difficulty in differentiating between the fetus that is constitutionally small and fulfilling its growth potential and the small fetus that is not fulfilling its growth potential because of an underlying pathologic condition. The purpose of this document is to review the topic of fetal growth restriction with a focus on terminology, etiology, diagnostic and surveillance tools, and guidance for management and timing of delivery.
胎儿生长受限，又称宫内生长受限，是一种常见的妊娠并发症，与多种不良围产结局相关。胎儿生长受限的术语、病因和诊断标准尚未达成共识，对于生长受限胎儿的最佳管理和分娩时机也存在不确定性。此外，还存在一个挑战，即难以区分因潜在病理状况而未能发挥生长潜能的胎儿和因先天因素而本身较小的胎儿。本文件的目的是回顾胎儿生长受限这一主题，重点讨论术语、病因、诊断和监测工具，以及管理和分娩时机的指导。
