Angiography > Exams & Procedures > Thoracic Angiogram (AAA assessment)

This is an arterial study to look at the major blood vessels that arise from the aorta to look for any abnormalities, i.e. aneurysms. Local anaesthetic is injected into the skin to numb the area. A small, thin tube commonly called a catheter is inserted in an artery, usually the femoral artery, located in the groin region. The catheter is then placed in position to best view the aorta. The vessels are viewed with the injection of contrast through the catheter.

Once the radiologist has viewed the pictures taken, he/she will then press on the puncture site for about 10 minutes.

The procedure takes about one hour. You will be on bed rest for three hours after the procedure.
