In the second trimester, up to 5% of twins undergo death of one or more fetuses. Co-twin prognosis after single fetal death: a systematic review and meta-analysis. Carolina Bibbo:[email protected]: (617) 732-5452 Julian Robinson: [email protected]: (617) 732-5445There is no role in antepartum fetal surveillance for uncomplicated Di-Di or Mo-Di twin gestations.
Following the demise of one twin after 14 weeks, the risk of demise of the co-twin is 12-15% in a monochorionic pregnancy and 3-4% in a dichorionic pregnancy. Antepartum fetal surveillance is reserved for twin pregnancies complicated by maternal or fetal disorders that require antepartum testing, such as fetal growth restriction. We are happy to respond to general questions about twin pregnancies.
Limited UGI with water-soluble contrast shows prompt contrast transit through the band without pooling within gastric pouch of distal esopahgus. Stomal diameter is mm without evidence for stomal stenosis.[Gastric pouch is not seen given unadjusted band.] No herniation of distal stomach through the band to suggest [anterior/posterior] prolapsed or symmetric pouch dilation or gastric erosion. TECHNIQUE: Risks and potential complications were explained and a informed was written consent.Appropriate osseous union without residual fracture lucency.Fracture margins are ill-defined suggesting resorption or hyperemia associated with early inflammatory/reparative process.The concordance rate of major congenital malformations is approximately 20% in monozygotic twins. Discordant fetal growth is defined as a 20% difference in the estimated fetal weight between the larger and the smaller twin.** Romero R, Nicolaides K, Conde-Agudelo A, Tabor A, O'Brien JM, Cetingoz E, Da Fonseca E, Creasy GW, Klein K, Rode L, Soma-Pillay P, Fusey S, Cam C, Alfirevic Z, Hassan SS Vaginal progesterone in women with an asymptomatic sonographic short cervix in the midtrimester decreases preterm delivery and neonatal morbidity: a systematic review and metaanalysis of individual patient data. Those pregnancies with discordant growth and at least one growth-restricted fetus have been associated with a 7.7 fold increased risk of major neonatal morbidity.
