Monochorionic pregnancies have placental anastomoses that to varying degree create a common circulation. This presents unique challenges for the performance of selective termination in cases of acardiac twin, twin to twin transfusion syndrome, or discordant twin abnormalities. Multiple methods of interrupting the affected twin's circulation have been attempted with variable success.

A case of twin to twin transfusion syndrome is reported. These babies were disclosed severe anemia in one twin and intense plethora in another one. The different appearence was coincided with hematologic results. So, anemic patient was treated with transfusions and Plethoric one managed with vensections. Literature review was made on this subject.

Virtually all monochorionic twin placentas contain vascular connections between the circulatory domains of each twin. In contrast, vascular anastomoses are generally thought not to occur in fused, dichorionic placentation. In the twin-to-twin transfusion syndrome (TTTS) one twin is preferentially perfused by blood from the cotwin via unbalanced placental vascular anastomoses. This vascular shunting results in twins born with discrepant weights, colors and hemoglobins. When one of the TTTS criteria was not present, the pregnancy was defined as "pseudo" TTTS. In pregnancies complicated by "pseudo" TTTS indicate that small twins have abnormal cord insertion more frequently than large twins. We present a case of vascular anastomoses in dichorionic diamniotic-fused placentas resulting in "pseudo" TTTS with a brief review of the literatures concerned.

A case of twin to twin transfusion syndrome, associated with monozygotic twin fwas presented At birthm twin A weighted 2900gm and was plethoric, Hemoglobin value of twin A was 20.4gm/100ml and hematocrit 61% Twin B weighted 2250gm and was markedly pale, cynotic and hemoglobin value at virth was 4.3gm/100ml and hematocrit 13% So venesection by use of femoral venipuncture was done at twin A and fresh whole blood was transfused to twin B, On 6th day, both infants wer discharged against doctor's order with improcved general condition and sucking.

Twin-to-twin transfusion syndrome (TTTS) is a severe complication of monochorionic twin pregnancies, characterized by the development of unbalanced chronic blood transfer from one twin, defined as donor twin, to the other, defined as recipient, through placental anastomoses. The incidence of TTTS in monochorionic diamniotic gestations is approximately 10% to 20%. The natural history of severe TTTS is well established with mortality approaching 80% to 100% if left untreated, especially when it presents at less than 20 weeks' gestation. This review presents overview of what is known about the pathophysiology and the diagnosis of TTTS, the markers for early detection of TTTS, treatment options available for TTTS, and complications of treatment for TTTS.

Two cases of monochorial twins with twin-to-twin transfusion syndrome were presented. In both of two cases, cases, there were marked difference in hemoglobin levels between two identical twins but in one of two cases, the anemic two was more larger than the pletoric one in birth weight unusually. In one of two cases, both anemic infant and plethoric one survived, but in the other case, both succumbed.

Monoamniotic twin pregnancies are relatively rare, occuring in 1 percentage. But perinatal mortality is 50-60 percentage. The high mortality rate has been attributed to preterm delivery, cord entanglement, twin-to-twin transfusion syndrome, intrauterine growth retardation and congenital anomalies. However, the desirable management plan of the monoamniotic twin pregnancies is still not established and there are controversies regarding the proper antepartum care of monoamniotic twins and the optimal timing and mode of delivery. We have experienced one case of monoamniotic twin without cord entanglement and both fetuses survival by cesarean section at 36+3 weeks, is reported with a brief review of the literatures.

OBJECTIVETo explore the clinical manifestations and short-term prognosis of twin-twin transfusion syndrome (TTTS) in neonates with different disease stages, receiving different intrauterine interventions, or as blood donors and recipients.

METHODSThe study retrospectively collected 76 TTTS neonates who were hospitalized in the Neonatal Ward, Peking University Third Hospital. The participants were classified into mild TTTS (n=38) and severe TTTS groups (n=21), or into amnioreduction (n=20), laser surgery (n=21), and expectant therapy groups (n=32), or into donor (n=23) and recipient groups (n=30).

RESULTSThe severe TTTS group had higher incidences of brain injury, heart disease, asphyxia, and renal damage and in-hospital mortality rate compared with the mild TTTS group, but the differences had no statistical significance. The laser surgery group displayed decreasing trends in the incidences of brain injury, heart disease, and renal damage and in-hospital mortality rate compared with the amnioreduction and expectant therapy groups. The recipient group had higher incidences of heart diseases and pathological jaundice than the donor group (P<0.05). The donor group had higher incidences of asphyxia and renal damage than the recipient group, but with no significant difference.

CONCLUSIONSThe neonates with severe TTTS have higher rates of organ damages and in-hospital mortality. Intrauterine laser surgery seems to lead to a better prognosis compared with the amnioreduction and expectant therapy. The recipients are more susceptible to heart diseases and pathological jaundice, whereas the donors are more susceptible to asphyxia and renal damage.
