[The initial results of fetoscopic laser treatment for severe second trimester twin-to-twin transfusion syndrome in the Netherlands are comparable to international results].

OBJECTIVE

Evaluation of the initial results of selective fetoscopic laser coagulation of placental blood vessels for severe second-trimester twin-to-twin transfusion syndrome in the Netherlands.

DESIGN

Prospective cohort study.

METHOD: Between August 2000 and December 31, 2002, 49 patients were included with severe second-trimester twin-to-twin transfusion syndrome. Treatment took place in the Leiden University Medical Centre and consisted of selective fetoscopic laser coagulation of anastomoses along the vascular equator on the placental surface. Follow-up was complete until six weeks after delivery.

RESULTS

Median gestational age was 20 weeks at fetoscopy and 34 weeks at birth. Perinatal survival rate was 65% (64/98). The treatment resulted in at least one surviving child in 80% of pregnancies.

CONCLUSION

The results of fetoscopic laser treatment for severe second-trimester twin-to-twin transfusion syndrome in the Netherlands are similar to the recent results in specialised foreign centres.
