Fetus-Placenta-NewbornObstetric and perinatal outcomes from The Australian and New Zealand Twin-Twin Transfusion Syndrome Registry*
Section snippets
Material and methods
In 1995 a national twin-twin transfusion syndrome registry was established in Australia and New Zealand, with the central registry location at the Women and Infants Research Foundation, Perth, Western Australia. The principal aim of the registry was to assess contemporary management strategies and outcomes in prenatally identified cases of twin-twin transfusion syndrome. All tertiary obstetric hospitals in Australia and New Zealand were contacted regarding the registry, and their participation
Results
During the 3-year period from November 1995 to November 1998, a total of 112 cases of twin-twin transfusion syndrome were reported to the national registry from 13 centers within Australia and New Zealand. These centers represented the majority of tertiary obstetric units in Australia and the largest tertiary obstetric unit in New Zealand. The principal criterion used for diagnosis was a severe discrepancy in amniotic fluid volumes in twin gestations known or thought to have monochorionic
Comment
Our national registry of cases of twin-twin transfusion syndrome clearly demonstrates this condition to have significant perinatal mortality and morbidity rates, even with accepted contemporary management strategies. Because the condition is uncommon, most centers would have limited experience in the management of twin-twin transfusion syndrome and compilation of large numbers from a single center would be difficult. This registry, operating for 3 years, has received information on 112 cases of
