ABSTRACT
PURPOSE:
To evaluate the type of umbilical-portal anastomosis in late-onset fetal growth restriction (LO-FGR) and appropriate for gestational age (AGA) fetuses. To investigate the impact of the type of umbilical-portal anastomosis on the adverse outcomes in LO-FGR.METHOD:
This study observed 150 pregnancies with AGA fetuses and 62 pregnancies with fetuses with LO-FGR. In each case, the point of reference for measuring the abdominal circumference was established. The type of umbilical-portal anastomosis was evaluated as T-shaped, X-shaped, and H-shaped according to the shape of main portal vein and portal sinus. Incidences of the type of umbilical-portal anastomosis in AGA and LO-FGR fetuses were evaluated.RESULTS:
T-shaped anastomosis was the most common (56.7%) in the AGA group and X-shaped (66.1%) in the LO-FGR group. In LO-FGR, T-shape anastomosis was significantly lower and X-shape anastomosis was significantly higher than AGA (p < 0.001). X-shaped anastomosis was associated with LO-FGR and the RR was 2.3 (95% CI 1.5-3.6; p < 0.001). Incidences of admission to NICU and emergency C/S for fetal distress were higher in fetuses with X -shaped anastomosis in the LO-FGR (p < 0.05).CONCLUSION:
X-shaped umbilical-portal anastomosis have a prognostic significance in LO-FGR fetuses.Key words
