(Angiogram-Abdominal, Arteriogram-Abdominal, Celiac and Mesenteric Arteriography, Abdominal Arteriography, Abdominal Angiography)
An angiogram, also called an arteriogram, is an X-ray image of the blood vessels. It is performed to evaluate various vascular conditions, such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel), or blockages.
An abdominal angiogram is an angiogram of the blood vessels of the abdomen. An abdominal angiogram may be used to assess the blood flow to organs of the abdomen, such as the liver and spleen. It may also be used to deliver medication into structures of the abdomen to treat cancer or hemorrhage.
Fluoroscopy is often used during an abdominal angiogram. Fluoroscopy is the study of moving body structures, similar to an X-ray "movie." A continuous X-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail.
In order to obtain an X-ray image of a blood vessel, an intraarterial (IA) access to a blood vessel is necessary so that a contrast dye can be injected into the body's circulatory system. Contrast dye causes the blood vessels to appear opaque on the X-ray image, thus allowing the doctor to better visualize the structure of the vessel(s) under examination. Dye is injected into specific blood vessels in order to examine a particular area of circulation more closely, the procedure is referred to as superselective angiography.
Many arteries can be examined by an angiogram, including the arterial systems of the legs, kidneys, brain, and heart.
For an abdominal angiogram, access may be obtained through a large artery such as the femoral artery in the groin. Once access is obtained, the contrast dye is injected and a series of X-ray pictures is made. These X-ray images show the arterial, venous, and capillary blood vessel structures and blood flow in the abdomen.
Because of the development and improvement of diagnostic procedures, such as computed tomography (CT scan), ultrasound, and endoscopic retrograde cholangiopancreatography, abdominal angiography is used less than it was some years ago. However, angiography is preferred in certain situations.
Other related procedures that may be used to diagnose abdominal problems include abdominal X-rays, CT scan of the abdomen, and abdominal ultrasound. Please see these procedures for additional information.
An abdominal angiogram may be performed to detect abnormalities of the blood vessels within the abdomen or of the abdominal organs. Such abnormalities may include, but are not limited to, the following:
Other conditions that may be detected by an abdominal angiogram include tumors, hemorrhage, cirrhosis, gallstones, inflammation, and the invasion of a tumor into the blood vessels. Angiography may be used to deliver medications directly into tissue or an organ for treatment, such as clotting medication to the site of hemorrhage or cancer medication into a tumor.
An abdominal angiogram may be recommended after a previous procedure, such as a CT scan, and indicates the need for further information.
There may be other reasons for your doctor to recommend an abdominal angiogram.
You may want to ask your doctor about the amount of radiation used during the procedure and the risks related to your particular situation. It is a good idea to keep a record of your past history of radiation exposure, such as previous scans and other types of X-rays, so that you can inform your doctor. Risks associated with radiation exposure may be related to the cumulative number of X-ray examinations and/or treatments over a long period of time.
If you are pregnant or suspect that you may be pregnant, you should notify your doctor. Radiation exposure during pregnancy may lead to birth defects.
There is a risk for allergic reaction to the dye. Patients who are allergic to or sensitive to medications, contrast dye, or iodine should notify their doctor. Also, patients with kidney failure or other kidney problems should notify their doctor.
Because the procedure involves the blood vessels and blood flow of the abdomen, there is a small risk for complications involving the abdomen. These complications may include, but are not limited to, the following:
There may be other risks depending on your medical condition. Be sure to discuss any concerns with your doctor prior to the procedure.
An abdominal angiogram may be performed on an outpatient basis or as part of your stay in the hospital. Procedures may vary depending on your condition and your doctor's practices.
Generally, an abdominal angiogram follows this process:
After the procedure, you will be taken to the recovery room for observation. The circulation and sensation of the leg where the injection catheter was inserted will be monitored. A nurse will monitor your vital signs and the injection site.
You will remain flat in bed in a recovery room for several hours after the procedure. If the groin or arm site was used, the leg or arm on the side of the injection site will be kept straight for up to 12 hours.
You may be given pain medication for pain or discomfort related to the injection site or to having to lie flat and still for a prolonged period.
You will be encouraged to drink water and other fluids to help flush the contrast dye from your body.
You may resume your usual diet and activities after the procedure, unless your doctor advises you differently.
When you have completed the recovery period, you may be returned to your hospital room or discharged to your home. If this procedure was performed as an outpatient, you should plan to have another person drive you home.
Once at home, you should monitor the injection site for bleeding. A small bruise is normal, as is an occasional drop of blood at the site.
If the groin or arm was used, you should monitor the leg or arm for changes in temperature or color, pain, numbness, tingling, or loss of function of the limb.
Drink plenty of fluids to prevent dehydration and to help pass the contrast dye.
You may be advised not to do any strenuous activities or take a hot bath or shower for a period of time after the procedure.
Notify your doctor to report any of the following:
Your doctor may give you additional instructions after the procedure, depending on your particular situation.
