AIM: To determine infant survival and neonatal outcome after fetoscopic laser treatment of twin-to-twin transfusion syndrome (TTTS).
RESULTS: In 53/71(75%) laser-treated TTTS cases, at least one twin was liveborn and in 42/71(59%) cases at least one twin survived infancy. Fetal survival did not differ between donors [41/71(58%)] and recipients [46/71(65%), P=0.36]. Among liveborns, infant survival was 29/41(71%) in donors and 36/46(78%) in recipients (P=0.12). Infant survival did not correlate to maternal characteristics (age, BMI, smoking or parity), gestational age at treatment or severity of TTTS (Quintero stage). No TTTS infant born before 25 weeks of gestation survived the first week. Among the 87 infant survivors, 26 (30%) had an Apgar score <7 at 5 min, 47 (54%) developed respiratory distress syndrome, 10 (11%) showed signs of severe brain damage, nine (10%) renal failure, eight (9%) bronchopulmonary dysplasia, and five (6%) infants developed retinopathy of prematurity ≥stage 3. There was no significant difference in neonatal morbidity between recipients and donors.
CONCLUSIONS: Fetal survival after laser treatment was comparable to that reported by other international centers. There was no significant difference in survival or neonatal morbidity between donors and recipients. Major neonatal morbidity was common, and combined with extremely preterm delivery the prognosis of TTTS is poor.
