Laser therapy for twin–twin transfusion syndrome in a dizygotic monochorionic twin pregnancy: A case report

Fetoscopic Laser Photocoagulation for Twin-Twin Transfusion Syndrome in a Dizygotic Monochorionic Twins

“…Cases of MCDZ gestations complicated by TTTS were rarely reported. To the best of our known, only eight cases (including the case in this article) complicated by TTTS 2,12–17 have been reported. Table 2 summarizes the basic characteristics of these cases.…”

Twin-Twin Transfusion Syndrome After Radiofrequency Ablation in Dizygotic Monochorionic Triamniotic Triplet Pregnancy With Sex Discordance: A Case Report

“…It is generally viewed that MC twin pregnancy is monozygotic. Since 1970, Nylander and Osunkoya reported an unusual monochorionic placentation with sex discordant twins (6), an increasing number of clinical cases of MCDZ pregnancies have been reported (1)(2)(3)(4)(5)(6).…”

“…Monochorionic multiple pregnancy shows an increased risk of fetal and neonatal complications, such as TTTS and twin anemia–polycythemia sequence (TAPS). Although TTTS occurs in 8% to 15% of monozygotic monochorionic twin gestations ( 2 ), it should be taken into consideration when dealing with monochorionic triamniotic triplet pregnancy in clinical practice if two fetuses are kept.…”

“…Since a series of cases of monochorionic dizygotic (MCDZ) twin pregnancies have been reported (1)(2)(3)(4)(5)(6), more attention has been given to sex-inconsistent twin pregnancies in practice, which may be associated with the increased use of assisted reproductive technology (ART) (1). However, MCDZ triplet pregnancy with sex discordance has rarely been reported.…”

“…Monochorionic multiple gestations are related to an increased risk of fetal and neonatal complications. Twin-twin transfusion syndrome (TTTS) occurs in 8% to 15% of monochorionic (MC) twin pregnancies ( 2 ), resulting in an imbalance of the blood flow due to anastomosis of the placental communication vessels. Fetoscopic laser surgery (FLS) is considered to be the preferred treatment for selected cases ( 1 ), which blocks the process of the disease by clotting the placental communication vessels.…”
