Perinatal and neonatal outcomes for fetoscopic laser ablation for the treatment of twin twin transfusion syndrome at a single center.

OBJECTIVE

To describe the perinatal and neonatal outcomes of fetal laser ablation (FLA) for the treatment of twin-twin transfusion syndrome (TTTS) in our single center institution.

STUDY

DESIGN

Retrospective study of 76 treated pregnant women. Procedural complications, perinatal and neonatal outcomes analyzed. Differences in outcomes between two procedural techniques, selective and Solomon, compared.

RESULTS

FLA occurred at median gestational age (GA) of 20.8 weeks (IQR 18.1-22.9) with low incidence of procedural complications (5.3%). High survival rate with delivery of at least one neonate (96%) [95% CI: 88.9-99.2%]; 73.7% [95% CI: 62.3-83.1%] were twins. Median GA at birth was 33.1 weeks (IQR 28.0-35.0). Neonatal mortality and morbidities were 9.4% and 48.3% of cases respectively, and associated with lower GA. Solomon cases had comparatively higher median GA, and lower incidences of neonatal morbidities.

CONCLUSION

Our small single center study showed favorable outcomes for using the Solomon technique in the treatment of TTTS.
