Abstract
Objectives - Compared to singleton pregnancies, monochorionic twins have increased rates of perinatal morbidity and mortality, believed due in part to both twin-twin transfusion syndrome and an increased risk of congenital anomalies. Here we describe the prevalence of noncardiac structural anomalies in monochorionic twins with twin-twin transfusion syndrome who underwent laser surgery. Methods - In a retrospective study of 221 consecutive cases of twin-twin transfusion syndrome treated with laser surgery, noncardiac anomalies were identified by review of antepartum and neonatal medical records. Results - Of 377 live-born twins, 19 (5.0%) had a noncardiac anomaly. This rate was increased for donor versus recipient twins (8.5% versus 2.0%; P< .01). The presence of an anomaly was unrelated to the Quintero stage, the presence of donor intrauterine growth restriction, or 30-day survival of the donor or recipient. Conclusions - The prevalence of noncardiac anomalies in pregnancies complicated by twin-twin transfusion syndrome who underwent laser surgery was higher in donors versus recipients.
