What is a Mesenteric Artery Duplex Scan?
A Mesenteric Artery Duplex scan is an ultrasound test. The superior and inferior mesenteric arteries branch out from the abdominal aorta. They supply the intestine with blood. In addition to vessel blockage, the study is used to detect any enlargement which is the result of an abdominal aortic aneurysm. An aneurysm is a bulge in an artery caused by a weakening in the vessel wall.
