Umbilical Artery Doppler

Objective: To describe perinatal outcomes achieved with cord occlusion (CO) in monochorionic twins with severe selective intrauterine growth restriction (sIUGR) and abnormal umbilical artery Doppler in the IUGR twin (types II and III). Methods: We studied a consecutive series of 90 cases of sIUGR with abnormal Doppler treated with CO of the IUGR fetus. Abnormal Doppler was defined as continuous (type II, n = 41) or intermittent (type III, n = 49) absent/reversed end-diastolic flow. All cases presented at least one of the following severity criteria: gestational age (GA) <22 weeks, inter-twin estimated weight discordance >35%, reversed end-diastolic umbilical artery flow or ductus venosus pulsatility index >95th centile. We prospectively recorded pregnancy course and perinatal outcome. Results: Median GA at surgery was 20.6 weeks and mean duration 22.4 min. Miscarriage (<24 weeks) occurred in 3.3% (3/90) and preterm delivery <32 weeks in 7.1% (6/84) of continuing pregnancies. GA at delivery was 36.4 weeks and neonatal survival of the larger twin was achieved in 93.3%. Conclusion: In a consecutive series studied by an experienced team, CO in monochorionic twins with severe sIUGR type II or III was associated with delivery >32 weeks in 92.9% and neonatal survival of the normal twin in 93.3% of pregnancies.

Early Onset Preeclampsia

Intrauterine growth restriction (IUGR) represents a serious condition that can lead to increased perinatal morbidity, mortality and postnatal impaired neurodevelopment. There are two distinct phenotypes of IUGR: early onset and late onset IUGR with different onset, patterns of evolution and fetal Doppler profile. In early onset preeclampsia the main Doppler modifications are at the level of umbilical artery, with progressive augmentation of the pulsatility index to absent or reverse end diastolic flow. The modifications of the cerebral, cardiac and ductus venosus circulation are generally present, but with different sequences. The late onset IUGR is determined by third trimester placental insufficiency that entails fetal hypoxia. The cerebro-placental ratio (CPR) and the pulsatility index of the middle cerebral artery (PI MCA) seems to be the main markers for both diagnosis and obstetrical management while umbilical Doppler PI is frequently normal. Also the sequence of Doppler alterations is neither specific nor complete. New protocols for the diagnosis and management of late onset IUGR need to be implemented.
