Angiography/Intervention Frequently Asked Questions

How long will it take?

That is very variable and depends on the type of test. A typical angiogram usually takes around 45 minutes, more complex procedures - 60-90 minutes.

Are there any after effects?

Some people are may get a hot flush from the x-ray contrast medium injection. In rare cases some patients may feel sick or come out in a rash. If you have ever had a reaction to iodine or contrast medium in the past it is important that you tell the nurses, radiographer and the radiologist.

Will I need an injection. I hate needles.

Part of the procedure involves a small injection of local anaesthetic, usually in the groin area. This freezes the skin allowing the remainder of the procedure to be more comfortable.

Can my partner/friend/colleague come in with me during the procedure?

The usual answer to this is no. There are fairly strict rules that all x-ray departments have to abide by, to keep the amount of radiation to the "public" as low as possible. There are exceptions made sometimes if for example an interpreter is needed, or the patient is a child. If you have particular concerns, contact the x-ray department who will be doing your test.

What are the risks of x-rays?

We always use as low a dose of radiation as possible. Problems from radiation dose are extremely rare. It’s much more dangerous to drive to the hospital for your angiogram than to be exposed to the radiation dose of the examination. Further information can be found by reading the National Radiological Protection Board's patient information leaflet "x-rays: How Safe Are They?"

I feel anxious, will I be able to manage the examination?

Yes, please talk you anxiety over with the radiologist who will do everything possible to set your mind at rest. In certain cases it may be possible to give you a sedative to help relax you during the examination. The radiologist will be able to talk more about this if you feel it may be necessary.
