How is Twin-Twin Transfusion Syndrome (TTTS) diagnosed?
The diagnosis of TTTS is made with an ultrasound evaluation shows a twin pregnancy with one placenta, twins of the same sex in separate amniotic sacs, and polyhydramnios in the recipient’s sac and oligohydramnios in the donor’s sac. Amniotic fluid volume is measured with ultrasound by determining the deepest pocket measurement from the patient’s skin to her back.
