case_images: At 24 weeks, two umbilical arteries and one umbilical vein were detected by conventional color Doppler ultrasound (Figure 1). A routine ultrasound scanning during hospitalization revealed a single umbilical artery at 31+3 weeks (Figure 1); umbilical artery thrombosis was considered.
case_images: Intraoperative gross view. AT (black arrows) was observed in this fetus; the umbilical cord was dull red in color and rigid (A), inserted into the center of the placenta (B).
