IUGR
Also written as: IUGR — intrauterine growth restriction
Intrauterine growth restriction; fetal growth below expected parameters, affecting surgical timing and outcomes.
Full Definition
Intrauterine growth restriction (IUGR) describes fetal growth that falls below the expected rate for gestational age, typically defined as estimated fetal weight below the 10th percentile. In fetal surgery, IUGR may be a contraindication to intervention or may develop as a consequence of the underlying condition requiring surgery. The presence of IUGR influences surgical timing, technique selection, and postoperative monitoring protocols. Editors should distinguish IUGR from small for gestational age (SGA) and understand the implications for risk stratification.
Usage
Usage note: Increasingly replaced by 'FGR' (fetal growth restriction) in contemporary literature.
