OBJECTIVE: To determine practice patterns for evaluation and treatment of Stage I twin-to-twin transfusion syndrome (TTTS) among international physicians.

METHODS: An e-mail cross-sectional survey of members from the IFMSS, NAFTNet and SMFM societies and participants at a Eurofoetus-sponsored TTTS meeting was undertaken between May 2008 and November 2008. Questionnaires consisted of physician demographics and their recommendations for managing Stage I TTTS. Alternative therapies to expectant management were assessed based on the following special circumstances of the patient: residence more than 200 miles from the center, severe symptoms, or a cervical length of = 15 mm.

RESULTS: Eighty-one surveys were returned, giving a response rate of 84%. Five surveys were excluded as a result of duplication or missing data. Of the remaining 76 surveys, 48 were from North America, 20 were from Europe and eight were from other continents. Expectant management was the predominant recommendation (78%), followed by amnioreduction (11%), laser ablation (11%) and septostomy (1%). Recommendations for amnioreduction were exclusively from North American centers. Laser centers recommended expectant management more frequently than non-laser facilities (89% vs. 59%; P

CONCLUSION: Expectant management remains the predominant management of Stage I TTTS. In some patient circumstances, North American centers are more likely to recommend amnioreduction while European centers are more likely to recommend laser therapy. A randomized controlled trial will be necessary to evaluate the most efficacious management strategy for Stage I TTTS.
