Successful Treatment of Twin—Twin Transfusion Syndrome by Occlusion of Placental Vessel Anastomoses Using Enbucrilate

SummaryObjectiveTwin—twin transfusion syndrome is a serious obstetric complication unique to monochorionic twin gestations. Occlusion of vessel anastomoses is recommended to improve the perinatal outcome.Case ReportA 36-year-old, gravida 1, woman had a monochorionic twin pregnancy which was found to be affected by twin—twin transfusion syndrome at 26 weeks' gestation. The condition was successfully treated by occlusion of placental vessel anastomoses using enbucrilate under color Doppler ultrasonographic guidance. At 35 weeks of gestation, two male infants were delivered by cesarean section. The birth weights of the babies were 2,470 and 1,750 g, and both were thriving.ConclusionTargeted therapeutic ablation of vessel anastomoses involved in twin—twin transfusion syndrome using color Doppler ultrasonographic guidance is minimally invasive and may effectively obliterate interfetal transfusion, contributing to the survival of both twins.
