Methods: The outcomes of 100 consecutive pregnancies with severe TTTS managed with selective fetoscopic laser ablation from March 2002 to June 2007 were examined. Survival and neonatal morbidity were analysed. Comparisons were made with the results from other studies of laser surgery with at least 100 pregnancies. Results: There were 100 women with TTTS treated with laser ablation; 34 stage II, 44 stage III and 22 at stage IV. Median gestation at time of laser was 21 weeks (range 18-28) and median gestation at delivery was 31 weeks (range 20-39). Overall perinatal survival rate was 151 of 200 (75.5%). Eighty five per cent had one or more surviving twins. The survival rate for stage IV TTTS was 88.6%, significantly better than for stage II (69.1%) and stage III (73.9%) pregnancies. The perinatal mortality rate for donors (30%) was not significantly different from recipients (19%), but the fetal death rate for donors was significantly greater than that for recipients (P = 0.03). Severe cerebral abnormalities were present in only 2.8% of newborns. The overall survival rate was comparable to other large series. Conclusions: These results for the management of severe TTTS are comparable to the best reported international series. Long-term follow-up is required and more research needs to be undertaken to further improve these results.
