What to expect

Angiography – what patients can expect

During the procedure, the patient is given local freezing at the needle site (similar to dental freezing). The radiologist will make a small incision in the skin. The incision is most commonly made at the site of major blood vessels such as the groin, arm and neck. A small catheter (tube) is inserted and contrast (dye) can then be injected to make the blood vessels and other internal structures visible on the X-ray. X-rays are used to guide and locate the position of the catheter (tube) until it reaches the area to be examined.

Patients may experience a mild discomfort and a warm sensation with the movement of the catheter and injection of contrast solution. The most common causes of discomfort are the application of the local anesthetic, and the need to stay still for periods while images are being taken. Please let the radiologist, technologist or nurse know if you are uncomfortable.

How long is this procedure?

Angiogram testing can vary from one to three hours. A period of rest will be required after the procedure to monitor blood clotting and to allow for sedatives to wear off. Additional bed rest is usually required when patients return home.

Interventional Radiology – what patients can expect

Like angiograms, interventional radiology procedures also involve making a small incision (cut) into the skin. Small instruments are inserted into the incisions for the treatment of blockages and other conditions.
