Management of Stage I twin-to-twin transfusion syndrome: an international survey
Abstract
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 < 0.01). When examples of special patient circumstances were presented, North American centers changed their recommendation from expectant management to amnioreduction more often than did European centers. However, a greater…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
