Duodenal obstruction due to aortoduodenal syndrome.

Aorta-duodenal syndrome(ADS)is a fairly rare clinic presentation of duodenum obstruction caused by dilated abdominal aortic aneurysm. The main symptoms are usually nausea, vomiting and palpable pulsatile abdominal mass. When it comes to diagnosis, the most useful imaging technique is computed tomography(CT) and the best treatment option is surgery.
