Embryo reduction in dichorionic triplets to dichorionic twins by intrafetal laser.
OBJECTIVE To describe a new technique for embryo reduction (ER) in dichorionic triplet (DCT) pregnancies. METHODS In 22 DCT pregnancies, ER to dichorionic twins was carried out at 11.3-13.9 weeks' gestation by ultrasound-guided laser ablation of the pelvic vessels of one of the monochorionic twins. RESULTS Intrafetal laser was successfully carried out in all cases, but ultrasound examinatio...
متن کاملBlood flow changes in dichorionic twins with growth discordance.
AIM The study evaluated the applicability of Doppler ultrasonography in predicting the course of pregnancy and neonatal outcome in dichorionic pregnancy complicated by growth discordance. METHODS Doppler examination of the umbilical artery (UA) and middle cerebral artery (MCA) was performed in 106 twins. Abnormal values of the UA pulsatility index (PI) were considered to be above the 95th per...
متن کاملPlacental weight and birth weight to placental weight ratio in monochorionic and dichorionic growth-restricted and non-growth-restricted twins
OBJECTIVE: The aim of the present study was to compare the placental weight and birth weight/placental weight ratio for intrauterine growth-restricted and non-intrauterine growth-restricted monochorionic and dichorionic twins. METHODS: This was a retrospective analysis of placentas from twin pregnancies. Placental weight and the birth weight/placental weight ratio were compared in intrauterin...
متن کاملDegree and Rate of Growth Discordance in Dichorionic Twins Conceived by In Vitro Fertilization
Objective. Our objective was to estimate degree and rate of discordant growth and its impact on perinatal outcome in dichorionic twin pregnancies conceived by in vitro fertilization (IVF) compared to those conceived spontaneously. Study Design. Growth discordance was defined as 90th percentiles for the study population. Adverse perinatal outcome was defined as 5-minute Apgar score <7 and/or adm...
متن کاملFirst-trimester growth discordance and adverse pregnancy outcome in dichorionic twins.
OBJECTIVE To evaluate the association between first-trimester growth discordance and adverse pregnancy outcome in dichorionic twin pregnancies. METHODS This was a retrospective cohort study of consecutive women with dichorionic twin pregnancies undergoing an ultrasound scan at our institution between 7 and 14 weeks' gestation. Study groups were defined by the presence or absence of ≥ 11% crow...
