What are the limitations of Catheter Angiography?
Patients with impaired kidney function, especially those who also have diabetes, are not good candidates for this procedure.
Patients who have previously had allergic reactions to x-ray contrast materials are at risk of having a reaction to contrast materials that contain iodine. If angiography is essential, a variety of methods is used to decrease risk of allergy:
- You may be given one or more doses of a steroid medication ahead of time.
- Contrast material without iodine may be used instead of standard x-ray contrast.
Catheter angiography should be done very cautiously—if at all—in patients who have a tendency to bleed.
