OBJECTIVE: It was the aim of this study to elucidate the clinical features of recipient twins with increased middle cerebral artery peak systolic velocity (MCA-PSV) after fetoscopic laser photocoagulation (FLP) for twin-twin transfusion syndrome.
METHODS: Serial Doppler velocimetry of the MCA was performed in 30 recipient twins before and after FLP. Clinical data and perinatal outcome were compared between cases with and without increased MCA-PSV.
RESULTS: Increased MCA-PSV was observed in 7 recipients (23.3%) within 14 days after FLP. MCA-PSV gradually decreased to <1.5 multiples of median in 6 recipients; however, 1 patient resulted in fetal demise subsequent to the demise of the co-twin. The incidences of fetal and neonatal demise and neurological morbidity were similar. No recipient was diagnosed as anemic at birth.
CONCLUSIONS: The increase in MCA-PSV in recipients following FLP appeared to be generally transitory; this differs from twin anemia-polycythemia sequence.
