To assess the rate of fetal loss following amniocentesis or chorionic villus sampling (CVS) in twin pregnancy, a singleton pregnancy is considered to be a viable pregnancy.

To estimate the chorionic villus sampling (CVS)‐related risk of fetal loss in twin pregnancy after adjustment for chorionicity, nuchal translucency thickness (NT), intertwin discordance in crown–rump

Obstetrical outcomes after first‐trimester chorionic villus sampling in twin pregnancies: A retrospective case–control study

This study aimed to compare the obstetrical outcomes of CVS in twin pregnancies and those in non‐intervention twin pregnancies.

Comparison of spontaneous fetal loss rates between women with singleton and twin pregnancies after mid‐trimester amniocentesis ‐ A historical cohort study

To assess and compare fetal loss rates before 28 weeks of singleton and twin pregnancies after mid‐trimester amniocentesis, a large number of cases involving twins and singleton pregnancies are considered.

Comparisons of pregnancy outcomes between twin pregnancies with and without second‐trimester amniocentesis

To assess the amniocentesis‐related pregnancy loss rate and preterm birth rate among twin pregnancies undergoing amniacentesis, a large number of pregnancies are classified as having at least one twin.

Pregnancy loss after amniocentesis in monochorionic and dichorionic twin pregnancies: Results from a large population‐based dataset

To determine the loss rate after amniocentesis in twins, a large number of patients with twins have had at least one miscarriage in the first trimester.

Obstetrical Outcomes of Amniocentesis or Chorionic Villus Sampling in Dichorionic Twin Pregnancies

Evaluating the procedure-related fetal loss and the obstetrical outcomes of these two procedures, chorionic villus sampling and amniocentesis in dichorionic twin pregnancies concluded that both procedures can be safely used individually.

Performance of first trimester screening for Trisomy 21 in twin pregnancies

To assess the performance of the Danish first trimester screening program in twin pregnancies, a large number of twins were screened for gestational diabetes and the number of conceptions was low.

Amniocentesis in Twin Pregnancies: Risk Factors of Fetal Loss

Factors providing a significant independent contribution in the prediction of miscarriage and fetal loss at any stage of pregnancy were monochorionicity (MC), large intertwin discordance in crown-rump length (CRL), low Pregnancy Related Plasma Protein (PAPP-A) MoM and nuchal translucency (NT) above 95th centile.

Chorionic Villus Sampling in Assisted Versus Spontaneous Conception Twins.

The pregnancy loss rate following CVS is similar in ART twins and in spontaneous twins, however, the risk of prematurity before 28 weeks is significantly higher in the ART group.
