Summary

Although routine ultrasound is offered during the third trimester of pregnancy, less than a quarter of newborns with intrauterine growth retardation (IUGR) are suspected antenatally.

The measurement of the right portal vein (RPV) diameter on the transverse abdominal view at the 32 weeks' scan may be a new a tool for detecting small-for-gestational-age (SGA) at birth. The irregular and collapsed aspect of the right portal vein (RPV) on the third trimester ultrasound could be used for identifying hypoxemic and growth-restricted fetuses.

However, to our knowledge, the only interoperator reproducibility study of this measurement was performed using the same stored images or datasets without performing a new examination.

The main objective of this study is to assess the intra and interoperator reproducibility of the measurement of the right portal vein diameter at the routine third trimester ultrasound.

The secondary objective is to quantify the interoperator reproducibility of the assessment of the aspect, normal or collapsed, of the right portal vein, using an evaluation grid.

Two referees will perform four successive measurements of the diameter of the right portal vein (RPV) during the same ultrasound examination at the third trimester. Each operator will qualify the appearance of the right portal vein as normal or collapsed using an evaluation grid, and will independently performe a series of two measurements using the same method.
