Rare spontaneous monochorionic dizygotic twins: a case report and a systematic review [PDF]

BMC Pregnancy and Childbirth, 2022
Background Monochorionic dizygotic twins are a rare condition, mostly related to assisted reproductive technology. This type of twinning is burdened by the same risk of pregnancy complications found in monochorionic monozygotic pregnancies.

Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously [PDF]

AJP Reports, 2013
Traditionally, monochorionicity has been regarded as synonymous with monozygosity. However, several recent cases of monochorionic dizygotic twins have shown that monochorionic twins can be dizygous.

Case Report: Identification of Germline Chimerism in Monochorionic Dizygotic Twins [PDF]

Frontiers in Genetics, 2021
Monochorionic twins are generally considered to be monozygotic, as monochorionic dizygotic (MCDZ) twins are extremely rare in natural pregnancies. Several studies have reported this rare occurrence, and most of these pregnancies have been conceived by ...

Monochorionic Diamniotic Twins with Sex Discordance: Case Series [PDF]

Diagnostics
Background and Clinical Significance: Ultrasonographic diagnosis of twin pregnancies has become routine, with chorionicity playing a crucial role in assessing associated risks. Traditionally, monochorionic (MC) twins were believed to derive from a single

Monochorionic twin pregnancies conceived through assisted reproduction: Maternal and perinatal clinical outcomes. [PDF]

Acta Obstet Gynecol Scand
ART‐conceived monochorionic twin pregnancies are associated with a higher burden of maternal complications compared with spontaneous conception. While fetal and neonatal outcomes did not differ significantly between groups after adjustment for relevant confounders, ART‐conceived pregnancies showed higher point estimates for several adverse outcomes ...

Society for Maternal-Fetal Medicine Consult Series #74: Cell-free DNA screening for aneuploidies: Updated guidance. [PDF]

Pregnancy (Hoboken)
Abstract In this Consult, we provide updated guidance on the evolving applications of cell‐free DNA (cfDNA) screening, including its use in detecting sex chromosome aneuploidies and microdeletions and its application in multifetal gestations. We compare cfDNA test performance with conventional screening methods and offer recommendations for managing ...

Early versus late amniotomy during twin labor. [PDF]

Int J Gynaecol Obstet
Abstract Objective This study evaluates whether timing of amniotomy affects labor characteristics and maternal and neonatal outcomes in twin deliveries. Methods This retrospective study was conducted at a single academic medical center and included dichorionic diamniotic (DCDA) twin pregnancies with a normal anomaly scan and a vertex‐presenting leading
