Audit of immediate outcomes for MCDA twins following laser therapy for twin-twin transfusion syndrome at the NSW Fetal Therapy Centre.

Objective: To audit immediate pregnancy and neonatal outcomes of selective laser photocoagulation of communicating vessels (SLPCV) for twin-twin transfusion syndrome (TTTS) at the New South Wales Fetal Therapy Centre.

Methods: Retrospective cohort study of 151 TTTS cases undergoing SLPCV between July 2003 and May 2013, evaluating procedural details, delivery and perinatal outcomes.

Results: The majority of cases were Stage III at SLPCV (56.

Outcomes of stage I TTTS or liquor discordant twins: a single-centre review.

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.
