After cesarean section, stage 3 TAPS was confirmed according to the ultrasound findings and hemoglobin results of the newborns and placenta examination after birth. Patient 2 was a nulligravida who was diagnosed with stage 2 TAPS at 18\u202fweeks of gestation. The patient underwent fetoscopic laser surgery. Ultrasonography monitoring of the MCA-PSVs was performed on a schedule after surgery, with a good status but selective intrauterine growth restriction of one cotwin. The newborns reached their normal development milestones after spontaneous preterm birth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Optimal management should be
