Arterio-arterial vascular anastomoses in monochorionic placentas with and without twin-twin transfusion syndrome.
We performed a matched case-control study to analyze the placental angioarchitecture, in particular the diameter of arterio-arterial (AA) anastomoses in monochorionic placentas from pregnancies with twin-twin transfusion syndrome (TTTS) compared to a control group of uncomplicated monochorionic placentas. Placental angioarchitecture was analyzed using colored dye injection. AA anastomoses were ...
متن کاملIncreased prevalence of fetal thrombi in monochorionic-twin placentas.
OBJECTIVE Fetal vessel thrombosis has been related to pregnancy complications and adverse neonatal outcomes in singleton pregnancies, but the clinical and pathologic characteristics of fetal thrombosis in twin pregnancy are still ill defined. METHODS To clarify the characteristics of fetal thrombosis in twins, we reviewed the histology slides and medical records of live-born infants of twin p...
متن کاملGuide wire assisted catheterization and colored dye injection for vascular mapping of monochorionic twin placentas.
Monochorionic (MC) twin pregnancies are associated with significantly higher morbidity and mortality rates than dichorionic twins. Approximately 50% of MC twin pregnancies develop complications arising from the shared placenta and associated vascular connections. Severe twin-to-twin syndrome (TTTS) is reported to account for approximately 20% of these complications. Inter-twin vascular connecti...
متن کاملThe promoter methylomes of monochorionic twin placentas reveal intrauterine growth restriction-specific variations in the methylation patterns
Intrauterine growth restriction (IUGR) affects the foetus and has a number of pathological consequences throughout life. Recent work has indicated that variations in DNA methylation might cause placental dysfunction, which may be associated with adverse pregnancy complications. Here, we investigated the promoter methylomes of placental shares from seven monochorionic (MC) twins with selective i...
متن کاملManagement of Monochorionic Twin Pregnancy
A monochorionic twin pregnancy is one in which both babies are dependent on a single, shared placenta. Around one-third of twin pregnancies in the UK have monochorionic placentas. Monochorionic placentation can also occur in higher-order multiples. There has been a recent increase in all types of multiple pregnancies with the increasing use of assisted reproductive techniques. Monochorionic (MC...
