The signs and symptoms of TTTS can vary, but common indicators include:
Discrepancy in amniotic fluid volumes: Polyhydramnios in the recipient twin and oligohydramnios in the donor twin. Discrepancy in fetal growth: The donor twin may appear smaller and have less amniotic fluid, while the recipient twin may appear larger with excess amniotic fluid. Visible differences in the twins' size on ultrasound. Possible signs of heart failure in the recipient twin due to fluid overload.
