This special type of X-ray exam helps your doctor find the blockage in the renal arteries and sometimes open the narrowed part with a balloon and stent.
Your doctor injects a dye into the renal arteries through a long, thin tube (catheter) to outline the arteries and show blood flow more clearly. This test is often performed at the time of restoring the blood vessel opening with a stent.
Your doctor uses renal angiography to see the vessels that supply blood to the kidneys.
For the kidneys to be able to work properly they need a good blood supply. If there is limited blood supply, the kidneys will not be able to filter the waste from the blood, urine will not be produced and waste is not removed from the body properly. If the kidney function worsens you may require dialysis to filter your blood for you.
Before a scheduled renal angiogram, your doctor reviews your medical history and performs a physical exam. You may also have one or more of the following examinations:
You’ll receive instructions on what you can or can’t eat or drink before your procedure.
The night before your procedure:
You will be given a sedative through your IV to help you relax and make you sleepy. We will need you somewhat awake to follow instructions, like holding your breath and to not swallow.
When the procedure is completed, the site where the catheter was inserted is closed a few different ways:
To avoid bleeding from the catheter insertion site, you need to lie relatively still or keep your wrist straight for several hours in the recovery area.
The catheter site may remain tender, swollen and bruised for a few days. There may be a small area of discoloration or a small lump in the area of the puncture.
You may take acetaminophen (Tylenol, others) in the recommended dose as needed for discomfort, or other medication as prescribed by your doctor.
You may need to avoid strenuous activity and heavy lifting for 24 hours after the procedure.
The physician will go over the results we found on your angiogram. Based on the angiogram findings, decisions will be discussed how to proceed further.
