OBJECTIVES: To investigate rates of progression, regression and stabilisation and outcomes for stage I twin-twin transfusion syndrome (TTTS) and significant liquor discordant (LD) monochorionic diamniotic (MCDA) twins referred to the New South Wales Fetal Therapy Centre between June 2007 and May 2013.
METHODS: Retrospective cohort study of 329 monochorionic referrals, of whom 47 had LD and 28 had stage I TTTS at presentation; 43 were stage I or higher at any time during surveillance. Clinical progression, rates of therapy, survival and associated complications were evaluated.
RESULTS: Of stage I cases, 64% (18/28) remained stable or regressed, with 60% (6/10) of those progressing becoming at least stage II within 2 weeks. Of LD cases, 7/47 (15%) progressed to stage I TTTS, 8/47 (17%) to stage II or higher and 3/47 (6%) to selective intrauterine growth restriction (38% total).
CONCLUSION: While a stable clinical picture was the most common outcome in stage I/LD presentations, progression to stage ≥ II TTTS occurred in 36 and 17% respectively, indicating that LD is not a benign finding. Rapid progression in the majority of progressive cases and modest overall survival rates support close surveillance of these pregnancies and investigation of laser therapy as a first-line treatment of stage I TTTS. © 2016 John Wiley & Sons, Ltd.
