OBJECTIVE: To assess perinatal outcome in monochorionic twin pregnancies according to different stages of severe mid-trimester twin-twin transfusion syndrome managed by fetoscopic laser coagulation of the placental vascular anastomoses. METHODS: In a prospective study fetoscopic laser therapy was performed in 200 consecutive pregnancies with severe mid-trimester twin-twin transfusion syndrome at a median gestational age of 20.7 weeks (range 15.9-25.3 weeks). Outcome data were analyzed for the whole group and separately for each stage according to the Quintero staging system. RESULTS: The overall survival rate was 71.5% (286/400), with survival of both twins in 59.5% (119/200) and survival of at least one of the twins in 83.5% (167/200). The median gestational age at delivery of liveborn neonates was 34.3 weeks (range 23.1-40.4 weeks). There was a significant trend toward reduced survival rates with increasing stage (P=.038). The percentage of pregnancies with survival of both fetuses was 75.9% (22/29) for stage I, 60.5% (49/81) for stage II, 53.8% (43/80) for stage III, and 50% (5/10) for stage IV. At least one of the twins survived in 93.1% (27/29) at stage I, 82.7% (67/81) at stage II, 82.5% (66/80) at stage III, and 70% (7/10) at stage IV. The overall survival rate for donor fetuses was 70.5% (141/200) and for recipient fetuses, 72.5% (145/200). CONCLUSION: These data show that laser therapy is an effective therapeutic option for all stages of severe twin-twin transfusion syndrome and provide information to counsel patients according to the stage of the syndrome.
