A mesenteric artery ultrasound evaluates the arteries that supply blood to the intestines. Images are acquired using a hand held probe (transducer) that is applied to the abdomen.
This test is used to:
DO NOT eat or drink for 8 hours prior to this test. You may take small sips of water.
Please do not chew gum or smoke the day of the test.
If you are diabetic and unable to fast, please eat a low-fat diet (like toast, fruit or juice). No dairy products, carbonated beverages or beverages with caffeine.
When you eat, drink, or even chew gum, you swallow air into the stomach and bowel. Excess air in the bowel reduces ultrasound visibility of the mesenteric arteries. Fasting before the exam helps to minimize interference from bowel. In addition, information on blood flow through the mesenteric arteries is different in a fasting state versus non-fasting. Please let the sonographer know if you have not been fasting prior to this exam.
Take all of your medications at the usual times, as prescribed by your doctor. Small sips of water are okay.
You should feel no significant discomfort during this test. You will feel the pressure of the transducer on your abdomen.
This exam usually takes between 30-45 minutes, depending on many variables. After the test, you may go home or go to your other scheduled appointments.
After a vascular surgeon has interpreted your exam, the results will be sent to your referring physician and/or the vascular surgeon will go over the results with you during a follow-up appointment.
