WebIntestinal malrotation is any deviation from the normal 270 degree counterclockwise rotation of the midgut around the superior mesenteric artery that begins at the 6th gestational week with a prolapse into the umbilical cord and return of the midgut into the abdominal cavity between the 10th and 12th week.
