Jejunal Atresia

  • Etiology: in-utero vascular accident so it has no other associated congenital abnormalities
  • AXR: triple bubble sign
  • UGI: dilation of the duodenum and extreme dilation of the proximal jejunum and no distal passage of contrast on delayed images
  • Clinical: may see multiple atresias spiraling around the ileocolic artery (apple-peel atresia)
