Aortomesenteric clamp: association with Wilkie syndrome and nutcracker syndrome.

A 67-year-old female was referred due to epigastric pain, vomiting and weight loss of 6 kg in the past months. Blood tests were performed showing hematuria. An abdominal Doppler ultrasound did not show anything abnormal. Thus, an abdominal computed tomography (CT) angiography and a magnetic resonance imaging (MRI) enterography were performed, objectifying an aortomesenteric angle of 10.8° (reference range 38-56°), which caused a complete collapse of the left renal vein ("nutcracker phenomenon") and duodenal compression with retrograde dilatation ("Wilkie syndrome"). Conservative measures and nutritional support were adopted during hospitalization. She was discharged due to a good tolerance to an oral diet, the absence of symptoms and a good contrast pass in the esophagogastroduodenal transit.
