Abstract:
Objective To demonstrate that MRI is more advantageous than ultrasound in the detection of ischemic cerebral lesions precisely in twin-twin transfusion syndrome(TTTS)fetus following fetoscopic selective laser coagulation(SLCPV).Methods The fetus with TTTS treated by SLCPV were collected.All fetuses underwent brain MRI within 1-5 days after the procedure and a follow-up MRI at 29-32 weeks'gestation.All fetuses also had frequent ultrasound evaluation until delivery.Results Twenty-five pregnancies with TTTS were included in the study.Six pregnancies resulted in survival of only one twin after the procedure(Group A),while the other 19 pregnancies resulted in the survival of both twins(Group B),as assessed at the time of initial MRI.Two fetus in Group A and three in Group B had evidence of bleeding in lateral ventricle.Two fetus in Group B had actue brain ischemia.One fetus in Group B had appeared brain atrophy and choosed to terminate pregnancy.Conclusion MRI can make a clearer diagnosis of cerebral damage of TTTS fetus in a short period after SLCPV.
