Interventional Procedures

1. Which procedures are associated with higher radiations doses?

Interventional procedures, e.g. angiography and cardiac catheterisation and Computed tomography (CT) can be associated with higher doses of radiation (about 100 to 1000 times more than chest X ray).

2. What are the possible effects of radiation exposure from interventional procedures?

Most interventional procedures involve higher radiation doses than those used in diagnostic investigations with, typically, a 1/10,000 risk of skin injury and a small increased probability of cancer in future years. An interventional procedure performed under X ray fluoroscopy guidance often replaces a more invasive surgical procedure. Skin injuries are preventable in most situations with proper choice of technique. [interventional procedures]

3. What should I do if I find skin reddening?

Skin reactions or skin burn should be reported immediately to your doctor.

4. Should I be concerned about radiation if my child has been prescribed an interventional procedure?

Not really based on radiation risk alone as the benefit of the procedure may overweigh the risks. Thus the issue is how much benefit is expected and to rule out if another procedure that does not involve ionizing radiation can serve the purpose.You might also bring a card for the doctor to write how much dose was given in the interventional procedure.
