Hepatic Angiography
Hepatic angiography is an imaging test. It uses X-rays to look at the blood vessels that send blood to your liver. The test uses a thin, flexible tube (catheter). The catheter is put into a blood vessel through a small cut (incision). X-ray dye (contrast medium) is then injected into the catheter. The dye makes your blood vessels show up more clearly on the X-rays. This procedure is usually done by an interventional radiologist. An interventional radiologist is a doctor who is specially trained and certified by the American Board of Radiology to use minimally invasive image-guided procedures to diagnose and treat diseases.
Possible risks
All procedures have some risks. The risks of this test include:
-
Bruising at the insertion site
-
Damage to your artery
-
Problems due to the X-ray dye, such as an allergic reaction or kidney damage
Getting ready for your procedure
Tell your healthcare provider if you:
Be sure your healthcare provider knows about any medicines, herbs, or supplements you are taking. You may need to stop taking all or some of these before your test. This includes:
Follow any directions you are given for not eating or drinking before surgery.
Also make sure to have a family member or friend take you home from the hospital. You won't be able to drive yourself.
During your procedure
-
You will change into a hospital gown and lie on an X-ray table.
-
An IV line will be put in a vein in your arm or hand. You’ll receive fluids and medicines through this IV.
-
You may be given medicine to help you relax and make you sleepy (sedation).
-
You will be given medicine (local anesthesia) to numb the skin near your groin. A guide wire is then put through the skin into a large artery in your thigh (femoral artery).
-
Using "live" X-ray images (fluoroscopy) as a guide, the radiologist will thread the wire through your arteries to your liver. A catheter is then put over the guide wire. The guide wire is then taken out.
-
X-ray dye will be injected into your artery through the catheter. This helps the arteries in your liver show clearly on X-rays.
-
You will have to keep still and sometimes hold your breath while X-ray pictures of your liver are taken. You may need to change position so that images may be taken from different angles.
-
When the test is done, the catheter is taken out. Pressure will be put on the insertion site for 10 to 15 minutes to stop bleeding.
After your procedure
-
You will be asked to lie flat with your leg stretched out for 6 hours to prevent bleeding at the insertion site.
-
You may be able to go home that day. Or you may be asked to stay in the hospital overnight. No matter when you are discharged, you should have a friend or family member drive you home.
-
Drink plenty of water to help flush the X-ray dye from your body.
-
Care for the insertion site as directed by your healthcare provider.
