To investigate the association between abnormal cord insertion and the development of twin‐specific complications, including birth‐weight discordance, selective fetal growth restriction (sFGR) and twin‐to‐twin transfusion syndrome (TTTS). 
Placental characteristics in different types of selective fetal growth restriction in monochorionic diamniotic twins
TLDR
This study aimed to explore the difference in placental characteristics among three types of selective fetal growth restriction in monochorionic diamniotic twin pregnancies and found the earlier onset time of sFGR II and III might be due to their higher placental territory discordance.
Perinatal outcome of monochorionic twin pregnancy complicated by selective fetal growth restriction according to management: systematic review and meta‐analysis
To explore the impact of severity and management (expectant, laser treatment or selective reduction) on perinatal outcome of monochorionic twin pregnancies complicated by selective fetal growth
Intertwin membrane cord insertion in dichorionic twin pregnancy: The description and comparison with other umbilical cord insertion types.
TLDR
Intertwin membrane insertion is a novel umbilical cord insertion abnormality and is a risk factor for poor pregnancy outcomes in twin pregnancies, according to this single-center cross-sectional study.

Intermittent absent and reversed umbilical artery flows in appropriately grown monochorionic diamniotic twins in relation to proximate cord insertion: A harmful combination?
To compare the prevalence of intermittent absent or reversed end‐diastolic flow (iAREDF) in the umbilical artery in appropriately grown monochorionic diamniotic (MCDA) pregnancies with and without
Placental Implantation Disorders.
The effect of placental location identified before delivery on birthweight discordance among diamniotic-dichorionic twin pregnancies: a three-year retrospective cohort study
TLDR
It is concluded that discordant birthweight is not affected by same location of diamniotic-dichorionic placentas, and the mean value nor the absolute difference in birth weight was associated with placental location combination.

TLDR
The association between VCI and TTTS may be overestimated and high-quality studies with a representative sample are needed in further research, but an association betweenVCI and BWD and sIUGR is suggested.

Birthweight in liveborn twins: the influence of the umbilical cord insertion and fusion of placentas
Objective To assess the relation of umbilical cord insertion and fusion of placentas with birthweight in monozygotic monochorionic, monozygotic dichorionic, and dizygotic twins.
Short‐ and long‐term perinatal outcome in twin pregnancies affected by weight discordance
The objective was to investigate the association between chorionicity‐specific intertwin birthweight discordance and adverse outcomes including long‐term follow up at 6, 18, and 48–60 months after

TLDR
The main aim of this study was to ascertain the performance of BW and ultrasound EFW discordance in the prediction of perinatal loss in twin pregnancies.
Outcome of monochorionic diamniotic twin pregnancies followed at a single center
TLDR
Evaluation of a cohort of monochorionic diamniotic twin pregnancies followed from the first trimester onwards at a single center finds no significant difference in the outcome of these pregnancies between the first and second trimester.
Velamentous cord insertion in monochorionic twin gestation. An added risk factor.
TLDR
VEL cord insertion and the CEN/VEL combination are indicators of high- risk subgroups within MC twins, and can be diagnosed by ultrasound, identifying these high-risk groups.
Significance of Velamentous Cord Insertion for Twin-Twin Transfusion Syndrome
TLDR
VCI in monochorionic twin pregnancies was not a risk factor for TTTS and severe perinatal morbidities, and there was no correlation between VCI and TTTS as a composite of adverse outcomes.
