Prenatal US Assessment of Superior Mesenteric Vessels for Digestive Rotation

Brief Title

Prenatal US Assessment of Superior Mesenteric Vessels for Digestive Rotation

Official Title

Prenatal Ultrasound Assessment of the Relative Position of the Superior Mesenteric Artery and Vein to Define the Status of Digestive Rotation: a Prenatal Tool of Intestinal Malrotation Diagnosis?

Brief Summary

      Digestive malrotation is an anatomical anomaly of the positionning of the mesenteric vessels
      and the digestive tract that can lead in some form to a dangerous neonatal complication:
      intestinal volvulus. This requires emergency surgery with a risk of digestive resection.
      Visualizing during pregnancy the normal or abnormal anatomical positionning of the mesenteric
      vessels could make it possible to diagnose this malrotation and prevent the occurrence of
      this complication.

      The aim of the study is ti evaluate the ability to identiy prenataly during ultrasound
      examination, the relative positionning of the fetal mesenteric vessels, and then to correlate
      it with the real postnatal positionning (gold standard)

Detailed Description

      -  Prenatal US assessment of mesenteric vessels positioning (relative position of the vein
           vs artery) during routine 3rd trimester US scan

        -  Description of various anatomical situation

        -  Comparison of this prenatal positioning with postnatal positioning obtained through
           abdominal ultrasound examination. Post-natal ultrasound being the gold standard
