Diagnosis and classification of selective fetal growth restriction in monochorionic twins

Diagnosis and classification of selective fetal growth restriction in monochorionic twins
Diagnosis: Estimated weight of one twin below the 10th percentile or discordance in estimated twin weights greater than 25%
Type 1: Normal/positive Doppler flow in the umbilical artery
  • Mild intertwin weight discordance
  • Usually favorable outcome for both twins: Very low risk of fetal demise of growth-restricted twin
Type 2: Absent/reversed end-diastolic flow in the umbilical artery
  • Poorest prognosis: High risk of fetal demise of growth-restricted twin
  • Mean gestational age at delivery: 29 weeks of gestation
Type 3: Intermittent absent/reversed end-diastolic flow in the umbilical artery
  • Intermediate prognosis: 10 to 15% risk of fetal demise of growth-restricted twin
  • Commonly survive to 32 weeks or more of gestation
