Stage Of Diagnosis

Twin-to-twin transfusion syndrome (TTTS) is an obstetric condition with high perinatal mortality, which develops when blood flows disproportionately from one fetus to another in a monochorionic twin pregnancy. Approximately 1 in 7 monochorionic pregnancies are affected with TTTS. The donor twin develops oligohydramnios and poor fetal growth, while the recipient twin develops polyhydramnios, heart failure and hydrops. Here we report two cases of severe TTTS in BIRDEM General Hospital 2 within a period of two years. It has been observed in different studies that, the mortality rate of both twins can be as high as 80% in TTTS depending on the stage of diagnosis and progression of the condition if untreated. In both our cases, the outcome was poor due to delayed diagnosis and lack of intrauterine therapies. So, there is an urgent need for timely diagnosis and appropriate management of this rare but complex condition which prompted us to report these two cases. Birdem Med J 2020; 10(3): 207-211

Introduction. Multifetal pregnancy is associated with an increased risk of perinatal morbidity and mortality. Type of placentation and discordant fetal growth may be risk factors of adverse pregnancy outcomes.Aim: to compare an impact of dichorionic and monochorionic twin pregnancies with symmetric and discordant fetal growth on perinatal outcomes, as well as morbidity and mortality.Materials and Methods. There was conducted a retrospective study of 485 pregnant women and paired 959 newborns. Depending on the type of chorionicity, subjects were stratified into two study groups being further subdivided into based on describing fetal weight discordance. The antenatal period and the neonatal outcome of newborns in groups and subgroups were compared.Results. We analyzed 308 dichorionic and 177 monochorionic twin pregnancies. It was found that neonate discordant growth was observed in 5.4 % and 13.4 % (p < 0.001), respectively. The incidence of assisted reproductive technologies was higher in dichorionic than in monochorionic twins comprising 66.5 and 40.7 % (р < 0.001). Antenatal mortality in monochorionic vs. dichorionic twins was by 8-fold higher. The preterm birth rate in monochorionic vs. dichorionic twins was 74.6 and 62.7% (p = 0.009), respectively. Neonate body weight in monochorionic vs. dichorionic twins was lowered comprising 1991 and 2430 gr. (р < 0.001), respectively. Low Apgar scores were more common for monochorionic twins with discordant body weight. The rate of early neonatal mortality in monochorionic vs. dichorionic twins was 4.4 % vs. 1.5 % (p = 0.009), whereas in dichorionic vs. monochorionic twins with weight discordance it was up to 5.8 and 10.5% (р < 0.001), respectively.Conclusion. Monochorionic twin pregnancy complicated with growth discordance is associated with a higher risk of adverse antenatal period as well as neonatal morbidity and mortality compared to symmetric DCDA twins. Chorionicity and growth discordancy represent important predictors for outcome of twin pregnancy.
