Also known as Wilkie's syndrome, this condition occurs when the third part of the duodenum is compressed between the superior mesenteric artery and the aorta. Under normal conditions, there is retroperitoneal fat around the third part of the duodenum, which avoids compression by creating an aortomesenteric angle > 28º.

Planning

Indications

Imaging is indicated in the presence of risk factors of the condition:[1]

  • Most common in females aged 10-39 years
  • Previous accentuated weight loss
  • Previous surgery for scoliosis
  • Anatomical variations in the ligament of Treitz, with consequent elevation of the duodenum
Signs and symptoms[1]
  • Postprandial upper abdominal pain that is relieved in ventral or left lateral decubitus
  • Nausea
  • Emesis
  • Weight loss

Choice of modality
