Abdominal arteriogram; Arteriogram - abdomen; Mesenteric angiogram
Mesenteric angiography is a test used to examine the blood vessels that supply the small and large intestines.
Angiography is an imaging test that uses x-rays and a special dye to see inside the arteries. Arteries are blood vessels that carry blood away from the heart.
This test uses x-rays and a special dye called contrast to make blood vessels show up on the images.
This test is usually done in the radiology area in a hospital. You will lie on an x-ray table. You may ask for a sedative if you are anxious about the test.
Certain treatments can be done during this procedure. These items are passed through the catheter to the area in the artery that needs treatment. These include:
After the x-rays or treatments are finished, the catheter is removed. Pressure is immediately applied to the puncture site for 20-45 minutes to stop the bleeding. After that time the area is checked and a tight bandage is applied. The leg is usually kept straight for another 6 hours after the procedure.
You should not eat or drink anything for 6 - 8 hours before the test.
You will be asked to wear a hospital gown and sign a consent form for the procedure. Remove jewlery from the area being imaged.
Tell your health care provider:
The x-ray table is hard and cold, but you may ask for a blanket or pillow.
You may feel a brief sting when the numbing medication (anesthetic) is given. You will feel a brief sharp pain as the catheter is inserted into the artery, and some pressure as it is moved into place. Usually you will only feel a sensation of pressure in the groin area.
As the dye is injected, you will feel a warm, flushing sensation. You may have tenderness and bruising at the site of the catheter insertion after the test.
This test is done:
A mesenteric angiogram may be performed after more sensitive nuclear medicine scans have identified active bleeding. The radiologist can then pinpoint and treat the source.
