Arteriogram
An arteriogram is also called an angiogram. An arteriogram is an x-ray image
of the blood vessels to evaluate various vascular conditions, such as an
aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel),
or blockages.
Arteriogram Procedure
In order to obtain an x-ray image of a blood vessel, an intravenous (IV)
access is necessary so that a contrast dye can be injected into the body's
circulatory system. This contrast dye causes the blood vessels to appear opaque
on the x-ray image. This allows the physician to better visualize the structure
of the vessel(s) under examination.
Many arteries of the blood can be examined by an arteriogram, including:
arterial systems of the legs, kidneys, brain, and heart.
Although each hospital may have specific protocols in place, generally, an
arteriogram procedure follows this process:
- The patient is positioned on the x-ray table.
- An intravenous line is inserted into a vein in the
patient's arm.
- The patient is connected to an EKG monitor that records
the electrical activity of the heart and monitors the heart during the
procedure using small, adhesive, electrode patches.
- A small incision is made in the arm or groin, into
which a small catheter is inserted.
- The catheter is threaded into the desired vein or
artery.
- An injection of contrast material is given.
- With the catheter in place, a series of x-rays are
taken.
- The catheter is then removed and pressure is applied
over the area to keep the artery from bleeding.
- The patient remains flat in bed in a recovery room for several hours after
the procedure.
After the Procedure
Once at home, the patient should monitor the incision for
bleeding, unusual pain, swelling, and abnormal discoloration or temperature
change in the arm or leg of the puncture site. A small bruise is normal. The
patient may be advised not to do any strenuous activities for at least 12 hours,
nor take a hot bath or shower.
