Feasibility of Fetal Portal Venous System Ultrasound Assessment at the FT Anomaly Scan.

At the end of the FT, the visualization of a normal L-shaped UV confluence, that excludes major PVS abnormalities, is achievable in approx. 80%, indifferently the examiners experience. The sonographers experience, pregnant women BMI, and uterine anomalies as fibroids or retroversion significantly affect the rate of visualization, and necessitates vaginal approach and reexamination. The FT pathology, the audit of the ultrasound findings can only be performed microscopically, with relatively little resources involved and good results.
