Background Information:
What are the other Names for the Procedure?
What is Catheter Angiography radiology procedure? (General Explanation)
- A Catheter Angiography uses MRI, CT, and x-ray catheters, with a contrast material to produce images of major blood vessels
- A thin tube, called a catheter, is inserted into the artery. The contrast material is injected through the catheter and images are captured
What part of the Body does the Procedure involve?
A Catheter Angiography procedure is mainly used to check blood vessels in different parts of the body, such as the neck, abdomen, heart, lungs, legs, pelvis, kidneys, and brain.
Why is the Catheter Angiography radiology procedure Performed?
- An angiogram is mainly used to check blood vessels in different parts of the body, such as the neck, abdomen, heart, lungs, legs, pelvis, kidneys, and brain. It can be used to identify lipid deposits or plaque in the arteries of the brain and legs
- Angiograms identify arteriovenous malformations in the brain
- Catheter Angiograms are also used during kidney transplantation, coronary bypass, stent implantation, and to identify injuries in arteries during trauma
- The procedure can also be used to detect endocrine diseases, pulmonary embolism, and arteries supplying blood to tumors
What is the Equipment used? (Description of Equipment)
The equipment used for a Catheter Angiography procedure consists of the following:
- A table
- An X-ray tube
- A computer monitor
An image intensifier located over the patient lying on the table, converts x-ray into a video image.
What are the Recent Advances in the Procedure?
There have been no recent advances to replace the Catheter Angiography procedure.
What is the Cost of performing the Catheter Angiography radiology procedure?
The cost of the Catheter Angiography procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion prior to Procedure?
- It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding a Catheter Angiography procedure and what needs to be done.
- If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician.
- Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently.

Prior to Catheter Angiography radiology procedure:
How does the Catheter Angiography radiology procedure work?
- A Catheter Angiogram works on similar principles as an x-ray machine
- X-rays are aimed at different parts of the body and an image is produced on a recording plate, using X-rays that have passed through the body
- A contrast material, such as barium, is also used to visualize the blood vessels
How is the Catheter Angiography radiology procedure Performed?
The Catheter Angiography procedure is performed as:
- In the preparation room, a nurse inserts an intravenous (IV) line into the arm
- A blood sample is drawn in to see that the kidneys are functioning properly
- The area where the catheter is inserted is shaved and numbed, with an anesthetic
- The catheter is inserted into the artery, by making a small incision into the skin. The catheter is guided to the area of interest
- The contrast material is injected through the catheter, to visualize the artery of interest. Several x-ray images are taken
- The catheter and IV are removed and the incision site is closed. The entire procedure may take anywhere from an hour to several hours to complete
Where is the Procedure Performed?
A Catheter Angiography procedure is performed as an outpatient procedure, at a hospital.
Who Performs the Procedure?
The following specialists may perform a Catheter Angiography procedure:
- Neuro-radiologists
- Neurosurgeons
- Pediatric neurosurgeons
- Vascular and interventional radiologists
- Vascular neurologists
How long will the Procedure take?
The Catheter Angiography procedure may take between 1-3 hours to perform.
Who interprets the Result?
- The radiologist or neurologist interprets the images taken from the Catheter Angiography, to determine any blockage of blood flow
- After the procedure, follow-up visits may be needed
What Preparations are needed, prior to the Procedure?
The following preparations may be needed prior to a Catheter Angiography procedure:
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient, including information related to the medications that are being currently taken
- Do inform the medical professional if you have a history of any medical conditions, such as a heart disease, asthma, diabetes, or kidney disease
- Do inform the medical professional about any allergies, especially related to barium or iodinated contrast material, which may be used in the procedure

- It is highly recommended to inform your healthcare professional, if you are pregnant or breastfeeding
- The patient may have to stay at the hospital overnight for observation and may need someone to drive them home, if given any sedatives.
What is the Consent Process before the Procedure?
A physician will request your consent for a Catheter Angiography procedure using an Informed Consent Form.
Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied with the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
What are the Benefits versus Risks, for this Procedure?
Following are the benefits of the Catheter Angiography procedure:
- By using this method, it is possible to diagnose and treat the condition at the same time. For example, narrowing of the artery can be fixed by angioplasty and placement of stent, during the procedure
- It may eliminate the need for surgery
- It produces very detailed images of the blood vessels
- The radiation does not stay in the patient’s body after the procedure
Following are the risks of the Catheter Angiography procedure:
- Over-exposure of radiation may cause cancer; though, this is very rare
- Contrast materials used in the procedure may cause an allergic reaction in some patients
- If contrast material leaks out under the skin, it may cause some skin damage
- Very rarely, a blood clot may form on the tip of the catheter and blocks the artery
- Internal bleeding may occur, if the catheter punctures the artery; however, this is also a very rare occurrence
What are the Limitations of the Catheter Angiography radiology procedure?
The Catheter Angiography procedure is not recommended for patients with kidney problems or diabetes.
