[Natural history of monochorionic diamniotic twin pregnancies with and without twin-twin transfusion syndrome].
PURPOSE to evaluate the evolution of monochorionic-diamniotic twin pregnancies with and without the twin-twin transfusion syndrome (TTTS), followed up in an expectant way. METHODS retrospective study in which the pregnancies with and without TTTS and with mild (Quintero's stage I) and severe (Quintero's stages II, III, IV and V) disease manifestations were compared according to extreme preter...
متن کاملAmniotic fluid and hemodynamic model in monochorionic twin pregnancies and twin-twin transfusion syndrome.
We developed a mathematical model of monochorionic twin pregnancies and twin-twin transfusion syndrome (TTTS), combining both fetal fluid dynamics and fetoplacental growth and circulation alterations and assuming that transplacental fluid flow from mother to fetus accounts for normal fetal and amniotic fluid volumes. Ten coupled differential equations, describing fetal total body and amniotic f...
متن کاملOutcome of monochorionic twin pregnancies with moderate amniotic fluid discordance adjoining twin-twin transfusion syndrome.
OBJECTIVES This study aimed to assess the perinatal outcome in monochorionic diamniotic (MD) twin pregnancies complicated by amniotic fluid discordance (AFD) adjoining twin-twin transfusion syndrome (TTTS). METHODS An observational study of 84 consecutive MD twin pregnancies complicated by AFD that resembled TTTS was conducted. AFD adjoining TTTS was defined by a maximal vertical pocket of am...
متن کاملErythropoietin in monochorionic twin pregnancies in relation to twin--twin transfusion syndrome.
Fetal erythropoietin (Epo) concentrations were studied in monochorionic (MC) twin pregnancies in relation to twin-twin transfusion syndrome (TTTS). Matched maternal and fetal blood samples in utero were obtained from MC twins with TTTS (n = 15) and without TTTS (n = 6). In a second group of five sets of twin pairs with or without TTTS, immunolocalization of Epo was performed in archived paraffi...
متن کاملThe Treatments of Twin-Twin Transfusion Syndrome in Monochorionic Twin Pregnancies by the Fetoscopic Laser Photocoagulation
Fetoscopic laser surgery for severe Twin-Twin Transfusion Syndrome (TTTS) has been conducted since early 1990s in United States and Europe. After the conclusion of Eurofetus in the randomized clinical trial [1], fetoscopic laser surgery has become the standard and optimal treatment for the TTTS condition. Recently, the techniques have been implemented throughout the globe; many institutions hav...
