Le résumé fourni par la source
The aim of this study was to assess the value of an unusual relative position of the superior mesenteric artery (SMA) and vein (SMV) to screen intestinal malrotation with a higher risk of volvulus. This was a prospective descriptive study conducted in our University's Hospital Center during four years (2012–2015). Evaluation of the relative position of the superior mesenteric vessels was performed during the routine second trimester ultrasound screening. Inclusion criteria were all fetuses between 19 to 22 weeks of gestation with no congenital malformation. The standard pediatric technique was followed. The relative position of artery and vein was defined on the abdominal axial scan including the visualisation of the left renal vein. For each fetus, the relative position of the vein was defined on the right, in front of or on the left of the artery. Normal position was defined as the vein on the right side of the artery. Other position was considered as unusual. If unusual position was diagnosed, prenatal MRI and newborn postnatal barium enema and upper gastrointestinal series were performed. 4000 patients were scanned during the four years period with 36 fetuses excluded because of impossibility to visualise the superior mesenteric vessels leaving finally 3964 included fetuses. Normal position of mesenteric vessels was found in 3949 fetuses. 15 unusual relative positions were diagnosed: 12 cases corresponded to the SMV on the left side of the SMA (2 fetuses confirmed as high risk of intestinal malrotation and 10 others as low risk) and 3 cases corresponded to the SMV in front of the SMA (finally considered to have no intestinal malrotation). Prenatal ultrasound assessment of the relative position of the superior mesenteric vessels might provide useful information in fetuses with intestinal malrotation. When the SMV are located on the left side of the SMA, further imaging evaluations in newborn are necessary to affirm diagnosis.
