📄 Report Sample Line- 00
The a monochorionic diamniotic twin pregnancy, Doppler sonography demonstrates significant intertwin discordance in middle cerebral artery peak systolic velocities (MCA-PSV). The donor twin shows elevated MCA-PSV (>1.5 MoM), consistent with fetal anemia, while the recipient twin demonstrates decreased MCA-PSV (<1.0 MoM), suggestive of fetal polycythemia. No evidence of amniotic fluid discordance or visible vascular anastomoses is noted. These findings are diagnostic of Twin Anemia-Polycythemia Sequence (TAPS), a chronic form of feto-fetal transfusion without oligohydramnios-polyhydramnios sequence.


Conclussion: 📋 Findings are consistent with Twin Anemia-Polycythemia Sequence (TAPS) in a monochorionic diamniotic twin pregnancy, as evidenced by significant discordance in MCA-PSV values between twins. The donor twin shows Doppler features of fetal anemia, and the recipient twin demonstrates features of fetal polycythemia. No amniotic fluid discordance is observed.
Recommendation: Serial Doppler surveillance of MCA-PSV and fetal growth is advised to monitor progression.
